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
De Bethune DB28 41 mm Mother-of-pearl Ceramic sits within De Bethune's DB28 line, introduced in 2011. It carries the house codes established since 2002 — ceramic case, mother-of-pearl dial and in-house manual-winding, hand-finished — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

Brand history
De Bethune has spent more than 24 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's DB28, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
David Zanetta & Denis Flageollet established De Bethune in 2002, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every De Bethune calibre produced today.
