Carillon tourbillon signature series two tone

Titanium is used for the watch’s mid-case and lugs, and the outer bracelet links, while the bezel, caseback, minute repeater slider, crown, center bracelet links, and bracelet clasp are all made of rose gold. This shows off the ways in which the two materials respond differently to hand-finishing and the result balances beautifully on the wrist.

Tastefully covering the calibre at the watch’s heart is a two-tone dial that combines a titanium base plate for sound quality and 18k gold for a distinctive look. The varied finishing and applied chemin de fer add visual depth and the applied white gold hour markers and faceted white gold hands make for a highly legible time display.

Now equipped with an Easy Adjustable Link that adds 4mm for optimal comfort year-round, our bracelet is crafted to complement Biver watches and composed of hundreds of hand-finished components—made with the same precision as our movements and dials.

Calibre JCB.001-B combines the practicality of automatic winding via a micro-rotor with the exceptional watchmaking of a carillon-style minute repeater and a tourbillon. It is also a perfect canvas for our expert decorators to show what true watchmaking art can be when every detail – seen and unseen – is treated with the utmost care and respect.
