Doxa Sub 300 Beta “Divingstar”

I wanted to share my insights about DOXA’s Sub 300 Beta watch as it represents their commitment to quality and functionality in an attractive package.

Design and Construction
The DOXA Sub 300 Beta’s classic yet contemporary design makes its presence felt immediately. Crafted in stainless steel, its case measures 42.5mm by 44.5mm by 11.9mm for perfect wrist size sizing; featuring AR-coated sapphire crystal for durability and clarity while an engraved caseback adds personalization for divers of any level. In total its 300m water resistance capacity ensures this watch provides reliable companionship during any diving adventure!

Bezel and Dial
One of the standout features of this watch is its unidirectional black ceramic bezel. The outer ring displays depth in feet using subtle tone-on-tone indications; there’s even a SuperLuminova dot at 12 o’clock for enhanced visibility in all conditions! On the interior ring are duration indicators in minutes also using tone-on-tone style indications for easy reading in all conditions!

The dials come in black, blue, grey or white hues with sunburst finishes and attractive wave patterns, highlighted with orange hands highlighted with SuperLuminova for functionality as well as style. A glossy black outer minute track adds to its sleek sophistication. Even though each watch is Sub 300 Beta, they all have individual names on the dial to differentiate them including; Divingstar, Professional, Aquamarine, Caribbean & Searambler.


At its heart lies DOXA Sub 300 Beta’s Swiss automatic Sellita caliber with 26 jewels and frequency of 28,800 vph, providing an amazing power reserve of 38 hours – impressive even among dive watches in this class! DOXA also adds their signature finishing touches with their decorated movement further personalising this remarkable piece.

DOXA provides ample flexibility with their Sub 300 Beta’s strap choices, giving users options ranging from the classic 20mm “beads of rice” steel bracelet to contemporary FKM rubber strap – each equipped with its own steel folding clasp – that offer comfort and durability, making this watch suitable for formal and adventurous settings alike.

Price Point
The DOXA Sub 300 Beta’s MSRP ranges between $2,250 to $2,290 making it competitive in the luxury dive watch market. Given its features and craftsmanship, this price point represents significant value to both collectors and enthusiasts of watches alike.


The DOXA Sub 300 Beta goes beyond mere timekeeping; it represents an incredible blend of tradition and modernity, functionality and style. Boasting robust construction, elegant design, and reliable movement; its strong presence will no doubt draw in those with an affinity for fine watches – particularly divers and aquatic adventurers who appreciate beautiful timepieces at reasonable price tags alike.  My only complaint is there is too much writing on the dial.With such an exceptional value proposition on offer here – The Sub 300 Beta looks set to revolutionise dive watch industry trends!

Due to the unpredictable and volatile market on certain Rolex, Patek Philippe and Audemars Piguet watches, prices are subject to change.
