Singapore-based Grail Watch is a platform that lines up collaborations that many enthusiasts have only dreamed about. For its latest project, Grail Watch 4, the company has brought together Bell & Ross and French designer Alain Silberstein to create the stunning Black Ceramic Trilogy based on the watchmaker’s iconic BR 03.

The Grail Watch Alain Silberstein x Bell & Ross Trilogy is comprised of a BR 03 time-only model with date, a BR 03 diving watch, and a BR 03 chronograph. All three watches are adorned with signature red, blue, and yellow accents that are signature touches in most Alain Silberstein designs. Each features a 42 mm x 42 mm square case and a black rubber band with an additional black fabric strap.

The time-only Klub 22 is a pure expression of Silberstein’s aesthetics with oversized geometric elements, including a red circle for the hours, blue arrows that read the minutes, plus an S-shaped hand and primary marks in yellow. The Marine 22 is the dive watch with maxi time indicators and a bezel with red details for the last 20 minutes. While both watches are powered by Bell & Ross calibre BR.CAL-302, the Marine 22 is depth rated to 300 metres and the Klub 22 is water resistant to 100 metres. As for the Krono 22, it features an automatic chronograph movement with date, the calibre BR.CAL-301, as well as a busier watch face with colourful pushers and crown.

The trilogy is available as a boxset, limited to 50, while the watches can also be purchased individually on Grail Watch’s website.
