DOXA welcomes Mélodie Treviño as Friend of the Brand — a union built on deep-sea exploration, marine conservation and the values behind the SUB watch.
Early Impressions
- Announced on 15 October 2026, the partnership pairs DOXA — the Le Locle-based Swiss watchmaker that first brought a public-market dive watch to market in 1967 — with a former national competitive diver turned conservation entrepreneur.
- Mélodie Treviño holds a PADI AmbassaDiver credential and has completed trimix dives to depths approaching 140 metres, including cave systems in the Yucatán and the Taam Ja’ blue hole in Mexico’s Chetumal Bay.
- She currently heads the Saving Our Sharks Foundation, which works to protect sharks and rays in the Mexican Caribbean through conservation, local community engagement and sustainable tourism.
- DOXA describes the partnership as a natural extension of the brand’s founding principle: producing reliable instruments for those who take the ocean seriously.

From the Pool to 140 Metres
Competitive sport gave Mélodie Treviño her first relationship with water; scientific curiosity drove her far beyond it.
Beginning as a member of Mexico’s national diving team, she redirected that athletic foundation toward technical and cave diving, two disciplines that reward preparation as much as physical capability. Her involvement in research at Taam Ja’, currently believed to be the deepest blue hole yet identified, and in the Xunaan Ha subterranean aquifer expedition, placed her inside environments where disorientation is a genuine risk and equipment reliability is non-negotiable. For collectors across the Gulf familiar with DOXA SUB watches through their association with serious underwater exploration, that context matters: the partnership is grounded in verifiable depth, not promotional convenience.
Conservation as the Continuation of Exploration
Treviño holds an MBA and has studied at the Yale School of Management and the University of Twente, a combination that informs how she approaches marine protection structurally rather than sentimentally.

At the Saving Our Sharks Foundation, she works to shift public perception of sharks and rays as keystone species, pairing conservation science with community-level economic incentives. As a DAN Global Ambassador, she also advances diver education and safety standards across the diving community.
DOXA’s Shared Position
DOXA was founded in Le Locle in 1889 and has spent the better part of six decades aligning itself with those who treat the ocean as a working environment.

The brand states that DOXA SUB watches were designed as genuine diving instruments, equally functional underwater and on dry land, built around precision, legibility and durability under pressure. In welcoming Treviño, the brand extends that alignment to a figure whose career connects athletic performance, scientific fieldwork and environmental advocacy. For a watchmaker whose identity rests on the ocean, the association carries weight that a conventional celebrity appointment would not.
