A watch’s headline size is only the beginning. Round watches are usually described by diameter, while rectangular, tonneau, cushion, and asymmetric cases need length and width together. Varcenne keeps those measurements separate so a case is not reduced to one misleading number.
Every published dimension carries an evidence status. Direct or reconciled values are tied to an exact-reference source. Inherited, inferred, and estimated values remain useful for discovery, but they are marked as such and should not be read as manufacturer precision.
Thickness is measured independently from the case footprint. Lug-to-lug and lug width are optional fields because many historical sources do not publish them. When a value is absent, the record says so rather than filling the gap with an unmarked guess.
For a particular watch, open the source links in the evidence panel and check the reference variant before comparing it with another model. A dial, material, bracelet, or movement change can create a different physical watch even when the family name stays the same.
