DOXA creates a unique SUB 300T for Fins Attached, water-resistant to 1,200m, to be auctioned at the Saving Our Seas Gala on 10 October 2026.
First Look
- Designated 1 of 1, this DOXA SUB 300T Sharksaver exists as a sole commission for Fins Attached, its caseback engraved with the date 10 October 2026 and the inscription FINS ATTACHED SAVING OUR SEAS FROM A MILE HIGH GALA.
- Water-resistant to 1,200 metres (120 ATM), powered by a Swiss automatic movement running at 28,800 vph with approximately 38 hours of power reserve.
- To be auctioned at the Saving Our Seas from a Mile High Gala — the sole route to ownership.
- The partnership funds shark research, conservation initiatives and community education through Fins Attached, founded in 2010.
Design and Mechanics
Measuring 42.50 mm across and 13.65 mm in thickness, the SUB 300T Sharksaver follows DOXA’s established dive-tool proportions precisely. The case is stainless steel throughout, fitted with a flat sapphire crystal, a helium release valve, and the brand’s patented unidirectional rotating bezel for calculating no-decompression dive times. A screw-down crown and screw-down caseback complete the pressure architecture.
The movement is a Swiss mechanical self-winding calibre bearing exclusive DOXA decorations, operating at 28,800 vph with 25 jewels and roughly 38 hours of power reserve. A date window sits at 3 o’clock. On the bracelet: DOXA’s well-known stainless steel “beads of rice” construction, with a folding clasp and a ratcheting wetsuit extension for use over drysuits.
The Conservation Context
DOXA announced the Fins Attached partnership on 28 September 2026. The brand donated the watch outright; proceeds from its auction at the Saving Our Seas from a Mile High Gala on 10 October 2026 will strengthen Fins Attached’s research and advocacy programmes. Jan Edöcs, DOXA CEO, stated: “DOXA’s legacy belongs in the ocean, but the ocean needs our protection. Supporting Fins Attached lets us turn our watchmaking passion into tangible support for vital marine ecosystems.”
Dr. Alex Antoniou, Founder and CEO of Fins Attached, responded: “Their generous support, and the donation of this exceptional custom watch, demonstrates a genuine commitment to ocean conservation.”
Auction and Ownership
Guests at the Gala will bid on the sole example in existence. No second piece will be produced. For a collector drawn to purpose-built dive instruments with traceable provenance, the combination of a documented cause, a unique caseback inscription, and DOXA’s 1967 dive-watch lineage positions this piece outside normal market comparisons. Its value, secondary or otherwise, will be set by what a single room of bidders decides on 10 October 2026.
