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
H. Moser & Cie. Endeavour 43 mm Black Platinum sits within H. Moser & Cie.'s Endeavour line, introduced in 1982. It carries the house codes established since 1828 — platinum 950 case, black lacquer dial and in-house automatic — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history
H. Moser & Cie. has spent more than 198 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Streamliner, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Heinrich Moser established H. Moser & Cie. in 1828, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every H. Moser & Cie. calibre produced today.
