Designer

In-house design studio

The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.

Historical significance

Yema Wristmaster 38 mm Ice Ceramic sits within Yema's Wristmaster line, introduced in 2023. It carries the house codes established since 1948 — ceramic case, ice blue dial and automatic, 38-hour reserve — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

  • The movement's bridges are decorated even where they will never be seen once the watch is cased.
  • The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history

Yema has spent more than 78 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Superman, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.

Henry Louis Belmont established Yema in 1948, working from France at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Yema calibre produced today.
