DOXA SUB 300β Seddiqi Edition 2023

Following the successful launch of the SUB 300β in Geneva last September – a SUB 300 with all of the icon’s the technical attributes, but slightly slimmer, more in tune with a contemporary urban lifestyle – DOXA today presents the limited edition: the SUB 300β Seddiqi Edition 2023, in honor of the brand’s prestigious partner in the Middle East, Ahmed Seddiqi & Sons.

Pearlescent elegance

On this occasion, DOXA is introducing – for the first time in the history of the SUB – a magnificent, deep sea blue dial in natural mother-of-pearl, bestowing each piece with a uniqueness akin to that of a fingerprint. Each mother-of-pearl dial being one-of-a-kind, never will you see the same dial on another wrist.

A sacred substance, mother-of-pearl imparts the dial of the SUB 300β Seddiqi Edition 2023 with a delicate, refined appearance that is all the more stunning for the magnificent natural iridescent effect. Mother-of-pearl is, by nature, full of mysteries and surprises. Depending on its origin, it varies in color and structure, influenced by the part of the shell from which it is derived.

DOXA has always believed in the continuous and careful improvement and development of its dive watches. This is particularly true for its most iconic timepiece, the SUB 300T, which remains one of the few dive watches to have left an indelible mark on Swiss watchmaking history.

The SUB 300β Seddiqi Edition 2023 honors the aesthetic codes that defined the SUB 300T’s legendary design, while adding a soft, subtle touch of contemporary elegance. The SUB 300β is slightly reworked to create a slimmer watch, with a profile of just 11.95 mm (compared to 13.65 mm for the SUB 300T) and a lower bezel height (by 0.5 mm) than on the SUB 300T.

With a diameter of 42.5 mm and a water resistance rating of 30 ATM (equivalent to 300 meters or just over 980 feet), the SUB 300β Seddiqi Edition 2023 is carved from a solid block of 316L stainless steel. It features the renowned DOXA-patented unidirectional rotating bezel – here, with a blue ceramic insert echoing the dial – that features dual scales for dive duration (in minutes) and depth (in meters) to calculate no-decompression dives. All diving-related indications of the dial are coated with Super-LumiNova®, ensuring optimal legibility underwater and in low-light conditions.

The rich sea blue of the mother-of-pearl dial offers a radiance and depth never before seen from DOXA, an effect that is magnified by the scratch-resistant sapphire crystal’s anti-reflective coating. The tried and true Swiss automatic movement ensures optimum reliability and a comfortable power reserve of approximately 38 hours.

The SUB 300β Seddiqi Edition 2023 is available with the historic ‘Beads of Rice’ bracelet in stainless steel, or with a white FKM rubber strap for a lighter more modern look. Both have a folding clasp featuring an adjustable wetsuit extension.

We are pleased to announce the unveiling of DOXA's 'SUB 300β Seddiqi Edition 2023 at Dubai Watch Week. Featuring a rich sea blue mother of pearl dial, the timepiece truly contributes to the contemporary elegance of the dive watch and highlights its unique characteristics," commented Mohammed Abdulmagied Seddiqi, Chief Commercial Officer, Ahmed Seddiqi & Sons.

Jan Edöcs, CEO of DOXA, added: “This summer, we launched a new concept at DOXA, the 'β factor,' which offers unique combinations of colors, materials, and textures. Today, I am thrilled to present the SUB 300β Seddiqi Edition 2023, an extremely exclusive series featuring, and this is a first for DOXA, a mother-of-pearl dial. Indeed, what better place than Dubai Watch Week for such a debut and to honor and express our gratitude to our dear friend and valued partner, Ahmed Seddiqi & Sons.”

While DOXA has upheld the tradition of crafting reliable and robust SUB dive watches since 1967, it is also a tradition of blending precision and elegance, grace and durability, beauty and technical performance. The SUB 300β Seddiqi Edition 2023 is available starting today at all Ahmed Seddiqi & Sons retail locations.
