The Biver AB is the brand's first watch in a steel case, marking a shift towards practicality. It features a new manual-winding calibre, priced at around CHF 68,000.
Biver AB: A New Direction in Design
Biver, the creation of Jean-Claude Biver and his son Pierre, has debuted its first steel case watch, the 'AB'. This move responds to customer demand for more practical wearability, departing from the brand's traditional use of precious metals. The watch incorporates a new manual-winding calibre instead of using an existing movement.

Biver AB Dimensions and Case Features
The Biver AB features a 38 mm by 9.8 mm case with a 19 mm strap width and 80 meters of water resistance. Its design retains familiar Biver elements, such as angular lugs with alternating finishes, reminiscent of vintage Patek Philippe models. The bezel is slightly larger, reducing the dial area.

What Makes the Biver AB Dial Special?
The standout feature of the Biver AB is its multi-level dial made of yellow gold. The center has a textured finish, contrasted by gold hands with hand-finished facets and gold 2N applique hour markers. The hour and minute scales are set on an onyx ring.

Inside the Biver AB: Calibre JCB-004
The Biver AB is powered by the calibre JCB-004, developed with Le Cercle des Horlogers. The movement is crafted from gold, aligning with the brand's core concept. It features a platinum and bridge made from white gold alloy PD210, which is highly corrosion-resistant. The movement offers a power reserve of approximately 120 hours, thanks to two series-connected barrels.

Additional Features of the Biver AB
The movement includes a power reserve indicator, subtly placed between 11 and 1 o'clock. It operates at a frequency of 3 Hz and includes a zero-reset feature for precise time setting.

Biver AB Bracelet and Pricing
The Biver AB comes with an angular bracelet featuring a patented micro-adjustment system activated by two buttons. This system will also be available in future models. A calfskin leather strap is included, which can be easily swapped using quick-release spring bars. The model is not limited in production, priced at approximately CHF 68,000 or $80,000.
