At a glance
Founded for complex movement work
CompliTime states that Robert Greubel and Stephen Forsey incorporated the company in 2001, assembling a team to create complications and grand complications for the horological industry.
That origin describes a supplier role rather than a consumer-facing watch brand. 1
Integrated services extend beyond the movement
The official site says CompliTime offers services from concept, design and movement development to final production, including cases and dials. It presents the work as an à la carte range for industry clients.
An individual project may use only part of that service range. 1
Testing and validation are part of the stated process
CompliTime describes a production workshop, test laboratory, quality controls and validation procedures. These are company capabilities and should not be converted into performance claims for an unnamed watch.
Use the final client's technical documentation for model-specific specifications. 1
Client confidentiality is explicit
CompliTime says it guarantees confidentiality and that its work for major names is contractually confidential. This explains why general attribution lists can be incomplete or absent.
Lack of a public client list is not proof of or against involvement in a particular watch. 1
Named examples are limited exceptions
The official site identifies Richard Mille Planetarium and Harry Winston Histoire de Tourbillon as examples of models produced by CompliTime. Those named examples should not be generalized into a broader claim about every line from those brands.
Treat each attribution as project-specific evidence. 1
Keep conclusions source-bounded
Official CompliTime material supports its 2001 foundation, integrated client services and confidentiality policy. It does not authenticate a watch, disclose all client work or establish value.
Use exact calibre and client-release sources for consequential attributions. 1
