Greubel Forsey is an independent Swiss watchmaker whose collections are built around distinct mechanical ideas, from traditional hand production to tourbillons and nanomechanics. The brand’s published specifications make two Balancier models especially useful to compare: the 39.6 mm Balancier QM and the 41.50 mm-caseband Balancier Convexe S2 Carbon. Its Hand Made 1 and Grande Sonnerie illustrate less conventional approaches, including hand-produced components and an elaborate striking complication. These details come from Greubel Forsey; they are not independent performance tests.
What makes a Greubel Forsey watch different?
Greubel Forsey is based in La Chaux-de-Fonds, Switzerland. The company describes its timepieces as the result of research and extensive hand work. That is the maker’s account of its practice, rather than an independent assessment of finishing or performance. Greubel Forsey’s brand overview provides its own framing of that work.
The brand organizes its watches into five collections, each associated with a different mechanical emphasis. The descriptions below reflect Greubel Forsey’s collection definitions. The official collections page is the place to check current line-up details.
| Collection | Greubel Forsey’s stated emphasis |
|---|---|
| Hand Made | Traditional hand production. |
| Balancier | Regulation by one or two balance wheels, without a tourbillon or additional complications. |
| Complications | Watches with one or more complications. |
| Tourbillon | Advanced tourbillon systems. |
| Mechanical Nano | Research into nanomechanics and energy efficiency. |
These categories describe different design priorities, not a simple ranking from basic to best. A buyer drawn to a particular collection should consider the mechanical approach and the specific watch’s dimensions and specifications.

Which Greubel Forsey model should you consider?
The answer depends on what you value: a smaller stated case diameter, a carbon-and-titanium construction, extensive hand production, or a striking complication. The examples below are not interchangeable, and the figures are model-specific specifications published by the maker.
Balancier QM: the smaller stated diameter
Greubel Forsey lists the Balancier QM in white gold with a 39.6 mm case diameter, 72-hour power reserve, and 3 atm water resistance. The brand states that production is limited to 33 pieces. Its one- or two-balance-wheel approach fits the broader Balancier collection description. See the Balancier QM product page for the maker’s current details.

Balancier Convexe S2 Carbon: carbon and an inclined balance
The Balancier Convexe S2 Carbon combines carbon and titanium, and the brand lists a 41.50 mm caseband diameter, 72-hour power reserve, and 5 atm water resistance. Its regulating architecture includes a 30-degree inclined balance system. Because the maker specifies the caseband diameter, do not treat that figure as directly equivalent to every other model’s stated case diameter. Greubel Forsey’s technical sheet gives the published details.
Balancier QM and Convexe S2 Carbon compared
| Model | Stated diameter | Case material | Power reserve | Water resistance | Regulating architecture | Production limit |
|---|---|---|---|---|---|---|
| Balancier QM | 39.6 mm case diameter | White gold | 72 hours | 3 atm | Balancier collection approach: one or two balance wheels, without a tourbillon or additional complications | 33 pieces, according to Greubel Forsey |
| Balancier Convexe S2 Carbon | 41.50 mm caseband diameter | Carbon and titanium | 72 hours | 5 atm | 30-degree inclined balance system | Not stated on the cited technical sheet |
The water-resistance figures are published specifications, not a complete guide to how a watch should be used around water. Confirm care and use guidance with the brand or seller rather than inferring an activity rating from the number alone.

Hand Made 1: a watch built around hand production
Greubel Forsey says Hand Made 1 is assembled, decorated, and machined entirely by hand, including a hand-produced regulating organ. The brand lists a white-gold case measuring 43.50 mm in diameter and 13.50 mm in height, a 60-hour power reserve, and 30 m water resistance. It states that production is one timepiece per year. These are the maker’s production and product claims, not independent findings. The Hand Made 1 page contains its official specifications.
Grande Sonnerie: a striking complication
The Grande Sonnerie illustrates the Complications collection’s more elaborate end. Greubel Forsey lists 935 components, two patents, three striking modes—Grande Sonnerie, Petite Sonnerie, and Silence—and a minute repeater on demand. The page also specifies 3 atm water resistance and states a one-per-year production limit. Component and patent counts, as well as the annual limit, are manufacturer-published claims; they do not establish reliability, service cost, or value. Consult the Grande Sonnerie product page for the brand’s description.

How large are Greubel Forsey watches?
The cited examples range from the Balancier QM’s 39.6 mm case diameter to Hand Made 1’s 43.50 mm diameter. The Convexe S2 Carbon is listed at 41.50 mm across the caseband, a differently named measurement. Hand Made 1 is also listed as 13.50 mm high. These figures help with a first comparison, but they do not tell the whole story of fit: case shape, thickness, lugs, and strap can affect how a watch wears. Where possible, try the specific model on or ask the boutique for fit guidance.
Where can you buy a Greubel Forsey watch?
For a new watch or a retail-partner inquiry, Greubel Forsey directs customers to its concierge and provides a point-of-sale route through its official contact page. The brand’s boutique listing names a Watches of Switzerland location at 60 Greene Street, New York.
Store details and available inventory can change. Before visiting or purchasing, confirm directly with Greubel Forsey or the retailer that the location is current, the seller is authorized, and the specific watch is available.
