Robert Greubel and Stephen Forsey's La Chaux-de-Fonds workshop produces, by general agreement among the most demanding contemporary collectors, finishing of an order rarely attempted at production scale anywhere else. Production is intentionally limited (under 100 pieces per year). Allocation through Greubel Forsey directly and selected retailers. Sourcing requires deep collector relationships.
A Greubel Forsey is defined by two things: the inclined-tourbillon architectures Robert Greubel and Stephen Forsey developed beginning in 2001 (the Double Tourbillon 30°, the Quadruple Tourbillon, the GMT Quadruple Tourbillon), and the finishing — bevels, inner-corner work, polishing — executed at a level that production-scale watchmaking has never previously achieved. The Hand Made 1, where every component is finished by a single watchmaker (the watchmaker who started the piece finishes it), is the workshop's most singular statement. Production is limited; allocation is concentrated; the secondary market is thin and tightly held.
Source a Greubel Forsey — Hand Made 1, Quadruple Tourbillon, Double Tourbillon 30°, GMT Quadruple Tourbillon, Balancier Convexe — through Maison Montres's collector network. Allocation through the La Chaux-de-Fonds maison directly and selected retailers; private collector network for discontinued and limited references. Twelve-point authentication on every sourced piece, with two-tier independent review mandatory given the complication architecture. No fee for the sourcing brief.
Hand Made 1. The workshop's most singular statement. Every component — every wheel, pinion, bridge, screw — finished by hand by a single watchmaker. Annual production: approximately two pieces. Sourcing is exclusively through deep collector relationships and the very rare auction appearance.
Quadruple Tourbillon. Four tourbillons (two double-tourbillon assemblies inclined at thirty degrees, paired and operating differentially) regulating a single mainspring. The most ambitious tourbillon architecture in production watchmaking. Limited production.
Double Tourbillon 30° / 30° Asymétrique. The original Greubel Forsey complication. Inclined-tourbillon architecture (one tourbillon at thirty degrees, rotating within a second tourbillon at four-minute intervals). The Asymétrique version — case shifted to display the architecture asymmetrically — is the workshop's most recognised piece.
GMT Quadruple Tourbillon. The Quadruple Tourbillon paired with the Greubel Forsey GMT system (the rotating globe display of world time). Combines the two most consequential workshop developments.
Balancier Convexe and Balancier Contemporain. The simpler Greubel Forsey — single-axis regulation, classical case, finishing at the workshop standard. The more accessible introduction to the brand, though "more accessible" is relative.
Tourbillon 24 Secondes Vision. A single inclined tourbillon, completed in twenty-four seconds rather than the traditional sixty. Distinctive case, hand-finished movement.
1. Brief. Open a sourcing brief specifying the reference (Hand Made 1, Quadruple Tourbillon, Double Tourbillon 30°, GMT, Balancier, Tourbillon 24 Secondes), case material, edition number where applicable, condition expectations, and budget range. For Hand Made 1, the brief includes a long-form collector statement that the workshop reviews — allocation requires the right collector profile.
2. Search. The Greubel Forsey workshop in La Chaux-de-Fonds controls allocation directly for current production. We work the workshop relationship for collectors with the right profile. The selected retailer network (a small group of authorised retailers in Geneva, Paris, London, Hong Kong, Singapore, Dubai) handles parallel allocation. The private collector network is the practical channel for discontinued and limited references; auction appearances at Phillips Geneva and Phillips New York are rare but consequential when they happen.
3. Authentication. Every Greubel Forsey passes our twelve-point intake protocol in Geneva, signed by a named watchmaker. Two-tier authentication with an independent specialist is mandatory on every Greubel Forsey — the complication architectures (inclined tourbillons, quadruple-tourbillon assemblies) require expert review, and the finishing standard requires verification by someone who has examined enough Greubel Forsey work to recognise authenticity.
4. Settlement. Inspection window on every transaction. Documentation transfers with the watch — original papers, presentation packaging, the timing certificate from the workshop, archive references where applicable, and the full Maison Montres dossier.
Greubel Forsey occupies a singular position in contemporary watchmaking. The workshop produces under 100 pieces per year. The finishing — the bevels, the inner-corner work, the polishing of every visible edge — is executed at a level that, by general agreement among watchmakers and the most demanding collectors, represents the upper boundary of what is currently achievable in production-scale work. The complication architectures (the inclined tourbillon, the Quadruple Tourbillon, the GMT system with its rotating globe) are technically distinctive in ways few other houses attempt.
The result is a house whose pieces trade as serious collector references with very thin secondary-market activity. Hand Made 1 in particular has become a reference point for what hand-finishing in serial production can achieve — annual production of approximately two pieces means the secondary market does not function in the conventional sense; pieces change hands through deep collector relationships when they change hands at all. For collectors building a portfolio of contemporary independent watchmaking at the highest finishing tier, a Greubel Forsey is a foundational position. Allocation requires the right profile, and even with the right profile, the wait is measured in years rather than months.
A Greubel Forsey sourcing brief takes a few minutes to draft. Reference, configuration, condition expectations, budget. Once received, the search begins — and the first response typically arrives within four business days.
Each brand sourcing page covers references in current demand, the sourcing process, and brand-specific FAQs. The first conversation is the same regardless of the house.
Through Maison Montres's sourcing network. Greubel Forsey allocation through the workshop directly is selective and depends on collector profile; the selected retailer network handles parallel allocation. For collectors without an established workshop relationship, we work the workshop directly on the collector's behalf — the brief includes a long-form collector statement that the workshop reviews. For discontinued and limited references, the private collector network is the practical channel. Every sourced piece passes our twelve-point authentication, with two-tier specialist review mandatory.
Greubel Forsey pieces have demonstrated some of the strongest long-term price retention in contemporary independent watchmaking. The Hand Made 1 in particular trades as one of the most valued single references; the Quadruple Tourbillon and Double Tourbillon 30° series have built consistent collector demand. For the collector evaluating Greubel Forsey, the centre of gravity is the inclined tourbillon — the 24 Secondes, the Double Tourbillon 30°, the Quadruple, and at the highest tier the Hand Made 1, where every component is finished by hand. Annual production at La Chaux-de-Fonds is in the dozens, and the secondary market for Greubel Forsey is essentially a function of personal reference: pieces change hands within networks of collectors who already own one. The wait — measured in years even with the right profile — is part of the proposition.
Workshop pricing is reference- and complication-dependent — broadly in the high CHF six-figure to low seven-figure range for the Double Tourbillon 30° and Quadruple Tourbillon series, with the Hand Made 1 in the upper seven-figure range. The Balancier Convexe and Tourbillon 24 Secondes occupy the lower end of the workshop's pricing. Secondary-market valuations on the rare references that come to resale have been at or above original workshop pricing for the most consequential references. Specific valuations are written reference by reference.
Maison Montres brokers Greubel Forsey disposals on the seller's behalf. Twenty-four-hour confidential valuation, no fee. Brokerage to our private collector network — where demand for Greubel Forsey at the right reference exceeds supply substantially — or to the major auction houses (Phillips Geneva and Phillips New York above all) where the gavel is the right channel for the most consequential references. Funds settle within forty-eight hours of authentication on private brokerage.
Every Greubel Forsey passes our documented twelve-point intake protocol in Geneva, signed by a named watchmaker. Two-tier authentication with an independent specialist is mandatory — the inclined-tourbillon and quadruple-tourbillon architectures require expert review, and the finishing standard requires verification by someone who has examined enough Greubel Forsey work to recognise authenticity. The dossier becomes part of the watch's permanent record.
Headquartered in Geneva at Place du Molard 5, with an additional office in Dubai (DIFC, Gate Avenue). All offices by appointment, Tuesday to Saturday. Reach the house at contact@maisonmontres.com or via WhatsApp.
