Following the launch of a SUB 300 limited edition with case and dial in forged carbon last year (you can read our hands-on review here), in 2021 DOXA is introducing six new SUB 300 Carbon COSC non-limited models with cases in forged carbon, colourful dials and rubber straps, either tone-on-tone to match the dial or black for a total of 10 versions.

Aquamarine ref. 822.70.241.25 and 822.70.241.20

With a diameter of 42.5 mm, the distinctively-shaped case of the SUB 300 Carbon COSC is waterproof up to a pressure of 30 bar (approximately 300 meters / 980 feet) thanks to a pressure-resistant titanium chamber and a screw-down crown.

Much lighter than steel, the forged carbon carbon has a special iridiscent texture that is the result of a sophisticated production process. The irregular pattern is achieved by working with randomly oriented carbon fibers. The reinforced structure is then heated and compacted to transform the soft, flexible layers into a super rigid and ultra-light form.

The case is equipped with the patented unidirectional rotating bezel for calculating and monitoring no-decompression dive times. It offers the dual indication of dive time and depth, expressed in minutes and meters respectively.

Another characterising element of the SUB 300 is the domed sapphire crystal with anti-reflective treatment. It reminds the curved Plexiglas used for the original series for a nice vintage touch while offering the advantage of being scratch-resistant.

It protects a dial where all the indications are clearly readable, even in poor light conditions thanks to the generous Super-LumiNova coating used for the hands and the indices.

These models are powered by a chronometer-certified version of the automatic ETA 2824-2 movement that beats at the frequency of 4 Hz (28,800 vibrations per hour) with a 38-hour power reserve. The COSC (“Contrôle Officiel Suisse des Chronomètres”) certification guarantees not only the chronometric performances of the watch but also its compliance with the highest standards in terms of precision, reliability and shock resistance.

The screw-in solid caseback is made of titanium and engraved with a sailing boat.

The soft rubber straps are equipped with a black PVD-coated folding clasp featuring an adjustable diver’s wetsuit extension.

The new DOXA SUB 300 Carbon COSC diving watches have a suggested retail price of CHF 3,790. Next week, we will publish our hands-on review of the Caribbean and Divingstar models. doxawatches.com
