Blomman Mr Blue shares an exciting acquisition: a Doxa SUB 300T Sharkhunter, notably a Synchron version with a meter-based bezel and no Aqua-lung logo, indicating its likely European market origin. This post highlights the subtle yet significant variations within vintage Doxa dive watches, a topic of enduring fascination for collectors.
Another one bites the dust!
This time the Doxa SUB 300T Sharkhunter.
The Synchron version with meter on the bezel instead of feet and without the Aqua-lung.
If I understood Bill correctly, this must have been a watch for the European market hence the meter scale and missing Aqua-lung/U.S. Divers Co.

This year have started very slow for me but I hope to add a Searambler before the year end, to cover my bases in this theme...
Once that is done, I guess it will be time to go into details!
Left to right:
CYMA SUB 300T Professional (meter/no Aqua-lung)
Doxa SUB 300T Sharkhunter (Synchron logo, meter/no Aqua-lung)
Doxa SUB 300T Professional (feet/Aqua-lung)

Yes, only time will tell what this year will bring..!

About the Doxa SUB 300T Ref. Sub 300T
The Doxa Sub 300T stands as an iconic pillar in diving watch history, representing the brand s legendary return to horological prominence after decades of dormancy. Originally established in 1889, Doxa achieved cult status among professional divers and collectors through their groundbreaking Sub series launched in the 1960s, which became synonymous with serious underwater exploration.

This reference embodies the authentic spirit of tool watch manufacturing, where form follows function in service of professional diving applications.
At the heart of the Sub 300T beats the robust ETA 2824-2 automatic movement, a proven Swiss caliber renowned for its reliability and serviceability.

The 42mm stainless steel case houses this mechanical engine while providing substantial water resistance to 300 meters, making it suitable for serious recreational diving. The unidirectional rotating diving bezel, crafted with precise detents, ensures accurate elapsed time measurement during underwater activities. A sapphire crystal with anti-reflective coating protects the distinctive yellow dial, which features the characteristic Doxa design elements including bold indices and the iconic fish logo.
The Sub 300T s collectibility stems from its perfect balance of historical authenticity and modern manufacturing quality. The vibrant yellow dial, known as Professional in Doxa terminology, represents one of the brand s most recognizable colorways, instantly identifiable to enthusiasts and continuing the legacy of the original 1960s models. This reference occupies a unique position in the contemporary dive watch market, offering collectors access to genuine diving heritage without the astronomical prices commanded by vintage examples.
