Greubel Forsey sourcing: invention and edition.
Maison Montres compares Greubel Forsey watches by invention, edition and case. Hand Made 1, Double Tourbillon 30° Technique and Double Balancier Convexe use different mechanisms and production records. Match the exact watch to its published specification, then review service history and seller evidence. Published rarity does not establish availability.
The maker's public pages establish published specifications and official retail routes. They do not show live stock or prove the identity, condition, title or price of a watch offered elsewhere.
Which Greubel Forsey mechanism and edition am I buying?
A small change in model wording can identify a different construction or production period. Use the full official name and reconcile it with the watch and papers.
| Model | Manufacturer record | Buyer decision |
|---|---|---|
| Hand Made 1 | The official page describes a hand-wound tourbillon assembled, decorated and machined by hand, with a stated pace of one timepiece per year and a 60-hour power reserve. | Treat any availability claim as candidate-specific. Confirm case, dial, number, delivery history and current service position. |
| Double Tourbillon 30° Technique | The maker's history records 188 pieces from 2009 to 2022. Its inner cage is inclined 30° and rotates in 60 seconds; the outer cage rotates in four minutes. | Match the exact material and execution. The history page lists several case materials across the series. |
| Double Balancier Convexe | The official 2023 page records two balances linked by a spherical differential, a titanium case, 72-hour reserve and 88 pieces for 2023–2026. | Confirm whether the offered watch belongs to this dated execution rather than another Double Balancier version. |
| Official retail enquiry | Greubel Forsey publishes boutiques, retail partners and a concierge enquiry route. | Ask the named official route directly about current availability; this guide cannot infer stock or allocation. |
| Pre-owned offer | Manufacturer specifications provide a comparison baseline only. | Reconcile reference, individual number, material, dimensions, functions, documents, condition and seller authority. |

What should a Greubel Forsey sourcing brief include?
Specify the Greubel Forsey mechanism, edition, case and service evidence you require to define a private sourcing brief. If you already have an offer, ask Maison Montres to review an identified candidate. Discuss the technical inspection and any dated market valuation as separate work.
- Full model name, invention, edition period, material and dimensions.
- Individual number, dial and movement images, and matching papers.
- Function test, condition report, service route and disclosed interventions.
- Seller capacity, transfer terms, tax status, insured transport and inspection window.
Published rarity is not live availability.
The production statements here come from Greubel Forsey's own pages, checked on 14 September 2026. Maison Montres does not claim a direct manufacturer relationship, allocation, prior transaction or access to any listed model.
- An “Express my interest” page is an official enquiry route, not proof that a watch can be ordered.
- Historical production data does not establish how many examples are currently saleable.
- No custody, title assurance, condition warranty or authenticity guarantee arises from this guide.
- A separate mandate should state role, fees, conflicts, inspection conditions and settlement path before work starts.

Greubel Forsey sourcing FAQ.
How many Greubel Forsey Hand Made 1 watches are made?
Greubel Forsey's official Hand Made 1 page states a production pace of one timepiece per year. That statement does not confirm present stock, a waiting time or whether a particular buyer can place an order.
Is the Double Tourbillon 30° Technique still a current series?
The maker's history page records 188 pieces produced from 2009 to 2022. A watch now offered under that name should therefore be checked as an individual secondary-market or retained-stock candidate, with its exact material and papers.
What distinguishes the Double Balancier Convexe 2023 edition?
The official page describes two balances linked by a spherical differential, a titanium case, a 72-hour power reserve and a limitation of 88 watches across 2023 to 2026. Other Double Balancier executions should not be assumed to share that specification.
Does this page prove access to a Greubel Forsey allocation?
No. Maison Montres makes no allocation or manufacturer-access claim here. Greubel Forsey's official boutique, retail-partner or concierge route must confirm new-watch availability. Any independent search requires separately agreed terms.
