Born from their partnership founded on shared values of horological heritage and excellence, they present today — on the occasion of Dubai Watch Week 2025 — a special edition of the SUB 300β that embodies their common commitment: to offer timepieces steeped in history that resonate with collectors and aesthetes, connoisseurs of Swiss watchmaking.

SUB 300 – DOXA’s iconic diver

In 1967, DOXA launched the then-revolutionary SUB concept, regarded as the first true professional diving watch made accessible to the general public. The groundbreaking innovations it introduced quickly made it the go-to tool watch even for uncompromising professionals.

 Back then, the SUB 300 was a 30 ATM (300 meters) water-resistant watch that, for the first time, incorporated a unidirectional bezel with a dual scale for dive time and depth. The US Navy's no-decompression dive table, allowing divers to monitor their time underwater relative to depth to ensure a safe return to the surface, had established itself as the definitive reference.

Inspired by the Navy’s model, the engineers at DOXA devised two distinct scales on the bezel — an orange outer ring indicating depth and a black inner ring indicating minutes — which enabled divers to calculate their dive times and thus ensure a safe ascent without decompression stops. It became a DOXA patent.

This watch quickly became a legend, easily recognizable for its bright orange dial: the bold – and practical color choice was also a first on a diver’s watch, contrasting with the traditional black, gray, or white dials of the era.

Starting in 1968, the SUB 300 was worn by the divers of the Calypso who took millions of viewers along on the legendary missions to explore The Undersea World of Jacques Cousteau.

Commander Jacques-Yves Cousteau, co-inventor of the modern scuba regulator and spiritual father of modern diving, so valued the SUB 300 that he negotiated exclusive distribution rights for the United States.

Capturing the spirit of the times: the SUB 300 Beta Ceramic

Following the SUB 300β Sharkhunter in black and gold, and the SUB 300β ‘Seddiqi Limited Edition’ featuring a deep ocean-blue mother-of-pearl dial — both introduced in 2023 — here comes the SUB 300 Beta Ceramic ‘Dubai Watch Week 2025’, with an unprecedented matte black and cherry red two-tone finish that is as stealthy as it is radiant.

The result is a masterful balance of proportions, materials, and colors connecting the watch to our times: a matte black ceramic case, a sunburst cherry red dial that plays with light, together forming a striking contrast with the hands and indexes generously filled with white Super-LumiNova®.

The bezel, with its indications engraved tone-on-tone in cherry red, subtly extends the dial’s color while enhancing the piece’s sporty character.

The DOXA SUB 300β is equipped with a supple black FKM rubber strap that matches the case, ensuring exceptional wearing comfort (it also comes with a timeless gray NATO strap included in its box). With all its cosmopolitan refinement, it remains a true dive watch with its deployant clasp and wetsuit extension, adorned with DOXA's hallmark ‘fish’ symbol.

The ‘β’ factor – for a slimmer, lighter, more elegant profile

‘β’ is for ‘Beta’: not just a remix of colors, materials, and textures. Always in tune with contemporary lifestyles, and mindful that dive watches must transition seamlessly from sea to city, DOXA has created a watch that perfectly combines toughness and urban sophistication.

Guided by the belief that a sports watch should be worn with ease in any situation, the SUB 300β Ceramic ‘Dubai Watch Week 2025’ preserves its original DNA while cultivating style and elegance. DOXA has subtly refined the design to achieve a slimmer watch with a case profile of only 11.95 mm and a bezel height 0.5 mm lower than the SUB 300T.

With a diameter of 42.5 mm, the SUB 300β ‘Dubai Watch Week 2025’ combines a pressure-resistant inner container in titanium to protect the movement, DOXA’s patented – and celebrated – unidirectional rotating bezel with dual indication of dive time (minutes) and depth (feet) for no-decompression dives, a screw-down crown, and a 30 ATM water resistance (equivalent to 300 meters) for underwater exploration in complete freedom.
