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
Bell & Ross BR-X1 42 mm Slate Ceramic sits within Bell & Ross's BR-X1 line, introduced in 1992. It carries the house codes established since 1992 — ceramic case, slate grey dial and automatic, swiss lever escapement — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.

Brand history
Bell & Ross has spent more than 34 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's BR 03, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Bruno Belamich & Carlos A. Rosillo established Bell & Ross in 1992, working from France at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Bell & Ross calibre produced today.
