The watchmaking industry has seen many examples of round dials in square cases, from brands like Omega, Jaeger-LeCoultre, Longines to name a few. For Bell & Ross, however, the concept of a “squared all-rounder” comes along the lines of a signature model.

Well-known for their history with the aviation and military industry, which often plays as an inspiration to their designs, the Swiss watch brand revealed the BR03-92 Diver this year at Baselworld.

Claiming it to be the first full-on square diving watch in the BR 0 family, the timepiece symbolises the special round and square mix – a Bell & Ross speciality. The watch meets the ISO 6425 standards which qualify it as a professional diving instrument suitable under extreme temperatures, violent acceleration or dangerous pressure. It is powered by a Swiss self-winding mechanical movement. The watch, offering water resistance up to 300 metres, is equipped with a rotating bezel on top that offers error-free legibility. Moreover, the bezel of the timepiece has been extended enough to make it easier to rotate at the 6, 9, and 12 o'clock positions.The hour and the minute hands encased in the dial are differentiated in size, shape and color. The hour hand is orange and the minute hand contains white Superluminova, helpful to make calculations underwater.

Designing square-cased diver watches is extremely difficult, and rare, because they're harder to make water-resistant – a feat which Bell & Ross has achieved. The case of the watch is designed in a way to make it withstand pressure. It is reinforced with a very thick back which is further soft iron caged to increase its resistance to magnetic fields. It also possesses a 2.85mm thick anti-reflective sapphire crystal.

Supplied in a Pelican case, the BR 03-92 is available in two straps- one in woven black rubber and one in ultra resilient black synthetic fabric. The Velcro closure system enables the watch to be quickly adjusted over a diving suit.
