Watchmaker Biver has launched the AB, a new stainless steel timepiece built to meet collector demand. The watch features a slim 38mm case and a sophisticated hand-wound movement.
Why it matters
The release responds directly to feedback from collectors who requested a steel model from the brand. Each piece is crafted individually by a single watchmaker to ensure high levels of technical precision.
The AB features a 38mm stainless steel case with a thickness of 9.8mm and a 120-hour power reserve. It is priced at CHF 68,000 and includes a white gold PD210 alloy mainplate.

Culture Shift
The move toward a stainless steel model reflects a growing preference among high-end collectors for versatile materials in luxury watchmaking. This strategy aligns the brand with a broader market shift that prioritizes both daily wearability and mechanical complexity.
Potential buyers should note that each watch is hand-built, which may impact overall availability at retail partners. The 38mm sizing offers a classic aesthetic that fits standard luxury watch styling conventions for daily use.
The takeaway
Collectors interested in the AB should monitor authorized distribution channels to determine availability given the hand-assembly process. Investing in such specialized timepieces requires an understanding of how individual watchmaker construction impacts long-term maintenance needs.
