Houses we work with, in two tiers.

Richard Mille

Founded 1999 · Les Breuleux

Engineering-led, materials-led, and built for an entirely modern collector. We handle the full breadth — limited and collaborative editions (RM 011, RM 035, RM 67, RM 030), the athlete editions (Nadal, Alonso, McLaren), the ladies' RM line, and the sapphire-cased and limited-production references. Two-tier authentication is standard on athlete editions and sapphire-cased pieces.

F.P. Journe

Founded 1999 · Geneva

The independent watchmaker whose work has, over twenty-five years, become the reference for contemporary collectors. We handle Chronomètre Souverain, the Octa series (Lune, Divine, Calendrier), Tourbillon Souverain, Astronomic Souveraine, Élégante, and the platinum boutique editions. Two-tier authentication is standard on early production and aluminium-movement pieces.

Patek Philippe

Founded 1839 · Geneva

The benchmark for finishing, complication, and long-term collectibility. Our work covers Nautilus and Aquanaut, the Calatrava in white and yellow gold, and the Grand Complications — perpetual calendars, minute repeaters, and split-seconds chronographs. Two-tier authentication is standard on vintage and Rare Handcrafts.

In demand

5711, 5712, 5811, 5980, 5970, 5270, 5740, 5396, the Rare Handcrafts series.

Mostly sourced through long-standing collector relationships; current production is allocation-only.

Seller

Complete sets and original Patek Philippe extracts essential; vintage with full archive provenance commands the highest realised prices.

Audemars Piguet

Founded 1875 · Le Brassus

The most consequential complications house of the 1970s, recast around the Royal Oak after Genta's 1972 design. Our work centres on Royal Oak references — early A- and B-series, Jumbo 5402, 14802, 15202, 15500, 15510, the 41mm 16202 — and the Royal Oak Concept and Code 11.59 in collector specifications. Two-tier authentication is standard on the Royal Oak archive (A and B series, 15202).

In demand

5402, 14802, 15202ST, 15500ST, 16202ST, 26240, 26331, 26420.

Buyer

Allocation increasingly difficult; we operate primarily on the secondary market and through private collectors.

Seller

Strong demand for full-set examples in mint condition. Vintage tropical dials and pre-2000 references command significant premium.

Jacob & Co

Founded 1986 · New York

High complication treated as theatre. Our focus is the Astronomia series (Casino, Solar, Sky), the Bugatti and Twin Turbo collaborations, the Opera Godfather, and the Epic X tourbillons. The brand has built a serious horological case in the past decade, and the secondary market for the most ambitious complications now trades like serious collector material.

In demand

Astronomia Casino, Astronomia Solar, Bugatti Chiron Tourbillon, Twin Turbo Furious, Opera Godfather.

Buyer

Limited series sold through Jacob & Co salons; private collector market for discontinued and athlete editions.

Seller

Liquid in the right references, particularly the Astronomia and Bugatti series. Documentation and original presentation essential.

MB&F

Founded 2005 · Geneva · by Maximilian Büsser

A laboratory for kinetic sculpture in mechanical form, founded on collaborations between Maximilian Büsser and a rotating cast of independent watchmakers. We handle the Legacy Machine series (LM1, LM2, LM Perpetual, LM Sequential EVO, LM SE Eddy Jaquet), the Horological Machine series (HM4, HM6, HM8, HM10), and the LMX and Triple Calendar editions. Two-tier authentication is standard on early production and limited editions.

In demand

LM Perpetual, LM Sequential EVO, LM SE Eddy Jaquet, HM6, HM8 Mark 2, LMX, Triple Calendar.

Buyer

Allocation through MB&F retailers and the M.A.D.Gallery network; private collector channels for discontinued production.

Seller

Demand consistently exceeds supply on the Legacy Machine series; original presentation and documentation essential.

Akrivia

Founded 2012 · Geneva · by Rexhep Rexhepi

Among the most consequential independent makers of the past decade. The Akrivia atelier produces under two names — Akrivia (the AK-series complications: tourbillons, monopusher chronographs) and Rexhep Rexhepi (the Chronomètre Contemporain series). We handle both. Resale market is thin, disciplined, and dominated by collectors who plan to hold for the long term.

In demand

AK-06, AK-07, the Tourbillon Monopousseur Chronograph, the AK Open, the AK-04.

Buyer

New pieces are allocation-only and the waiting list is closed for most references; sourcing happens almost entirely on the private collector market.

Seller

Demand far exceeds supply; valuations strong on original sets with full documentation.

Rexhep Rexhepi

Geneva · the named-line of the Akrivia atelier

The Chronomètre Contemporain (RRCC, RRCC II) is, by general agreement among collectors of contemporary independent watchmaking, one of the defining pieces of the past decade. The named-line of the Akrivia atelier represents Rexhep Rexhepi's most personal work — finishing of the highest order, classical case proportions, modest complications expressed with extreme refinement. Our work centres on the RRCC series and the Chronomètre Antimagnétique editions.

In demand

Chronomètre Contemporain II (Only Watch 2021), RRCC in platinum, RRCC II white gold, Chronomètre Antimagnétique.

Buyer

Allocations are subscription-only and the waiting list is closed; sourcing requires deep collector relationships.

Seller

Resale demand is among the strongest in contemporary independent watchmaking; original boxes, papers, and timing certificates command material premiums.

Simon Brette

Founded 2023 · Besançon · by Simon Brette

One of the most-watched debut workshops in independent watchmaking. The Chronomètre Artisans series — Brette's debut piece, hand-finished in Besançon — has become, in the space of two years, one of the references collectors of contemporary independent work most want to own. Production is intentionally limited; we handle the references that come to market, and we work the order book directly with the workshop where appropriate.

In demand

Chronomètre Artisans, Chronomètre Artisans No. 1 platinum, the limited gold editions.

Buyer

Direct relationships with the Brette workshop in Besançon; private collector market for the small number of pieces that have come to resale.

Seller

Resale market is thin but strong; complete documentation and direct provenance from the workshop are critical.

Voutilainen

Founded 2002 · Môtiers · by Kari Voutilainen

Among the most consistently revered finishers of the past twenty-five years. Kari Voutilainen's Môtiers atelier has produced, since 2002, classical pieces with hand-finished bridges, in-house dial work (often executed at Comblémine, the dial workshop Voutilainen owns), and complications expressed with restraint. Active across the Vingt-8 (the workshop's reference for the past decade), the Observatoire chronometer, the 28SC, and the 217QRS perpetual chronograph. Two-tier authentication standard on early production and limited-edition dials.

In demand

Vingt-8 (in white gold, rose gold, platinum), Observatoire, 28SC, 217QRS, the Comblémine-dial collaborations.

Buyer

Allocations subscription-only and the order book is closed for most current production; sourcing happens through the private collector network and direct workshop relationships when allocation becomes available.

Seller

Demand consistently exceeds supply. Original Comblémine dials and complete papers command material premium.

De Bethune

Founded 2002 · Sainte-Croix · by Denis Flageollet

Architecturally distinctive contemporary watchmaking — the heat-blued titanium, the floating lugs, the spherical moon — built around technical innovations (the silicon escape wheel, the triple parachute shock system, the spherical moon-phase) that few houses attempt. Active across the DB28 family (Steel Wheels, Kind of Blue, Yellow Submarine, GS Grand Bleu), the DB25 perpetual calendar, and the DBR05 Armilla rare-earth complications.

In demand

DB28 Steel Wheels, DB28 Kind of Blue, DB25 perpetual calendar, DB28xs Starry Sky, DBR05 Armilla.

Buyer

Allocation channels through De Bethune retailers and the maison directly; private collector network for discontinued and limited references.

Seller

Demand strong on Steel Wheels and Kind of Blue references in particular; original presentation and documentation essential.

H. Moser & Cie

Founded 1828 · Schaffhausen · re-launched 2005

A Schaffhausen house with one of the most distinctive contemporary identities — the dial-led aesthetic (Funky Blue, Streamliner, Vantablack), the in-house movement architecture, and the editorial voice that has defined the brand under the Meylan family ownership. Active across the Streamliner family (Centre Seconds, Flyback Chronograph, Tourbillon Vantablack), the Endeavour line (Centre Seconds Concept, Perpetual Calendar), the Pioneer Centre Seconds, and the Heritage Tourbillon.

In demand

Streamliner Centre Seconds, Streamliner Flyback Chronograph, Endeavour Concept Funky Blue, Endeavour Perpetual Calendar, Pioneer Centre Seconds.

Buyer

Allocation through H. Moser retailers and authorised boutiques; secondary collector market for discontinued and limited dial editions.

Seller

Streamliner family in particular has built strong secondary demand since 2020; original dials and presentation matter materially.

Grönefeld

Founded 2008 · Oldenzaal · by Bart and Tim Grönefeld

Dutch independent watchmaking at the highest finishing level. The Grönefeld brothers — third-generation watchmakers from Oldenzaal — have built an atelier whose work is defined by traditional Lange-school finishing, classical proportions, and complications executed with rigorous restraint. Active across the 1941 Remontoire (the workshop's flagship), the Parallax Tourbillon, the Decennium Tourbillon, the Principia (the simpler reference), and the recent Grönograaf chronograph.

In demand

1941 Remontoire (steel, rose gold, platinum), Parallax Tourbillon, Decennium Tourbillon, Principia, Grönograaf.

Buyer

Allocation is small and order-book based; the workshop produces approximately 50 pieces per year. Sourcing happens through the workshop relationship and the private collector network.

Seller

Resale demand is strong but the secondary market is thin; the right reference, with documentation, commands material premium.

Greubel Forsey

Founded 2004 · La Chaux-de-Fonds · by Robert Greubel and Stephen Forsey

A house defined by the inclined-tourbillon architectures Robert Greubel and Stephen Forsey developed beginning in 2001, and by finishing of an order rarely attempted at production scale anywhere else. Active across the Quadruple Tourbillon, the Double Tourbillon 30°, the GMT Quadruple Tourbillon, the Hand Made 1 (every component hand-finished by a single watchmaker), and the Balancier Convexe.

In demand

Hand Made 1, Quadruple Tourbillon, Double Tourbillon 30° Asymétrique, GMT Quadruple Tourbillon, Balancier Convexe.

Buyer

Allocation through Greubel Forsey directly and selected retailers; production is intentionally limited (under 100 pieces per year). Sourcing requires deep collector relationships.

Seller

Resale market thin and tightly held. Hand Made 1 in particular trades as one of the most valued single references in contemporary independent watchmaking.

Ferdinand Berthoud

Re-founded 2015 · Fleurier · by Karl-Friedrich Scheufele

A re-foundation of the eighteenth-century marine chronometer maker, under the patronage of Karl-Friedrich Scheufele (Chopard) and a workshop in Fleurier. Active across the Chronomètre FB 1 series (FB 1.1, FB 1.2, FB 1.3-1, FB 1.4), the FB 2RE in steel, and the FB RS skeleton. The pieces are produced in very small series — typically twenty pieces per reference — with chain-and-fusée power transmission and tourbillon regulation in the eighteenth-century chronometer tradition.

In demand

FB 1.3-1 (sapphire), FB 2RE in steel, FB 1.4 (rose gold), the limited dial-variant editions.

Buyer

Allocation through Ferdinand Berthoud directly and through the Chopard network. Production intentionally limited; sourcing channels are concentrated.

Seller

Resale market thin; FB 1 series in particular trades as a serious collector reference, with the FB 1.3-1 sapphire among the most valued.

Kurono Tokyo

Founded 2019 · Tokyo · by Hajime Asaoka

Hajime Asaoka's production-scale line, alongside his higher-tier Hajime Asaoka work. Kurono is the more accessible Asaoka — Japanese contemporary independent watchmaking with classical case proportions, dial work executed at a level rarely seen at the production scale, and movements built on Miyota base calibres finished and regulated to Asaoka's standard. Active across the Chronograph Reiwa, the Calendrier Type-1, the Mori (deep-green dial), the Anniversary editions, and the limited subscriber pieces.

In demand

Chronograph Reiwa, Calendrier Type-1, Mori, Anniversary 2nd, the Tokyo Edition pieces.

Buyer

Allocation through Kurono Tokyo's subscriber model and online drops; secondary market for discontinued and dial-variant pieces. Demand consistently exceeds supply on each launch.

Seller

Active secondary market on the dial-variant and subscriber-line pieces; original packaging and timing certificate matter.

Hazemann & Monnin

Founded 2024 · Switzerland · winner Louis Vuitton Watch Prize 2026

Alexandre Hazemann and Victor Monnin's Swiss workshop took the second edition of the Louis Vuitton Watch Prize for Independent Creatives in March 2026 — placing the duo, on the strength of one piece, in the contemporary independent conversation. The School Watch is the workshop's founding piece: an instantaneous jumping hour with a passing chime, presented in two interpretations (Hazemann's technical, blue-accented version; Monnin's artistic version with natural-stone dials including malachite and opal). Production scale is small. We are tracking the workshop closely and work direct relationships where allocation becomes available.

In demand

School Watch (both Hazemann and Monnin variants), and the upcoming dual-signature reference indicated by the workshop for late 2026.

Buyer

Allocation direct from the workshop, post-LV Prize, is selective. We work the workshop relationship for collectors with the right profile.

Seller

The secondary market does not yet meaningfully exist; resale would happen through private collector channels with full workshop provenance.

George Daniels

1926–2011 · Isle of Man · CBE, FBHI · inventor of the co-axial escapement

By general agreement among collectors of historic English watchmaking, the most consequential individual watchmaker of the twentieth century. Daniels produced approximately thirty-seven hand-made pieces in his lifetime and invented the co-axial escapement subsequently licensed to Omega. His work trades almost exclusively at auction, with private brokerage between collectors who already know each other. We work both channels for collectors who want a Daniels — not as an allocation relationship (the production is finished), but as a sourcing and authentication relationship through the auction calendar and private network.

References we work

The Space Traveller series, Spring Case watches, the Anniversary watch, the Grand Complication, the Millennium watches.

Channels

Phillips Geneva and Phillips New York consistently; private brokerage between Daniels collectors with documented provenance lines.

Authentication

Two-tier review with an independent Daniels specialist is mandatory on every piece. Provenance line is critical — we verify the chain of ownership back to original delivery from Daniels.

Roger Smith

Founded 2001 · Isle of Man · the Daniels apprentice

George Daniels' apprentice and the inheritor of the Daniels Method. Smith's Isle of Man workshop produces approximately ten pieces per year — the Series 1, 2, 3, 4, and 5 references — every one hand-made on the bench using the Daniels Method (the watchmaker who started the piece finishes it). Allocation is order-book only, and the order book has been closed since 2018. Sourcing happens almost exclusively through the private collector network and the major auction houses for the small number of Smith pieces that come to resale. Two-tier specialist authentication is mandatory.

References we work

Series 1 (open dial, 38mm), Series 2 (closed dial, 38mm), Series 3 (open dial, retrograde), Series 4 (open dial, triple calendar), Series 5 (perpetual calendar).

Channels

Phillips Geneva and Phillips New York where pieces come to consignment; private brokerage between Smith collectors.

Philippe Dufour

Founded 1992 · Le Solliat · production complete

The Simplicity, the Duality, and the Grande et Petite Sonnerie are, by general agreement among the most demanding contemporary collectors, three of the highest watchmaking statements of the past forty years. Dufour's Le Solliat workshop produced these references in extremely small numbers; the Simplicity in particular has become the reference point for what hand-finishing in serial production can achieve. Production is complete. Sourcing happens through the major auction houses (Phillips Geneva above all) and through private brokerage between Dufour collectors. Two-tier specialist authentication is mandatory.

References we work

Simplicity (yellow gold, white gold, pink gold, platinum — approximately 200 pieces total in the original 1990s-2010s series, plus the 2020 anniversary subscriber edition), Duality (the dual-balance regulator), Grande et Petite Sonnerie.

Channels

Phillips Geneva consistently; private brokerage between Dufour collectors with verified provenance.

Rolex

Founded 1905 · Geneva

The reference point of the secondary market — and, by extension, the reference point for liquidity. Rolex is not our active specialism. We handle Rolex brokerage on request, particularly for portfolio management clients and for collectors who arrive with a Rolex as part of a wider relationship. For collectors who specifically want to sell or source a Rolex and have no other relationship with us, there are houses with deeper Rolex order books, and we will name them.

References we handle

116500LN, 126710BLNR, 116710LN, 16610, 1675, 6263, 1601, 228238 — predominantly through portfolio management engagements.

Position

Brokerage on request, never on our own account; we never operate Rolex inventory.

Vacheron Constantin

Founded 1755 · Geneva

The oldest continuously operating watch manufacture, and increasingly the most interesting blue-chip alternative to Patek for serious collectors. Available on request — typically as part of a wider portfolio relationship. The Overseas (3rd and 4th generation), Patrimony, Traditionnelle, the 222 reissue, and the perpetual calendar references are the reference points where we engage.

References we handle

4500V, 7900V, 5500V, the 222 in steel and yellow gold, the perpetual calendar Overseas (4300V).

Position

On request, predominantly through portfolio management engagements.

A. Lange & Söhne

Re-founded 1990 · Glashütte

Saxon watchmaking at the highest level. Available on request — particularly the Lange 1, Datograph, Zeitwerk, and 1815 series. We do not lead on Lange; there are houses with closer Glashütte relationships and deeper Lange-specific specialism. For portfolio management clients who own Lange pieces, we handle them as part of the wider engagement.

References we handle

Lange 1, Lange 1 Time Zone, Datograph, Zeitwerk, 1815 Chronograph, the Saxonia line.

Position

On request, predominantly through portfolio management engagements; we will name better-placed houses where appropriate.
