The quick answer.
BODERRY Admiral GMT Black is a 40 mm gmt diver watch at $379 after code SEBASTIANBASSOL (before code $389). We recommend it for a traveler who wants a mechanical GMT, titanium bracelet and a high manufacturer-listed water rating in a single sporty watch.
Why it belongs on the shortlist.
The Admiral’s value rests in a specific combination: a recognizable GMT layout, NH34 automatic movement, titanium case and bracelet, sapphire and a screw-down crown. The black face and red-and-black 24-hour bezel keep the travel function legible while giving the 40 mm watch a more assertive look. BODERRY’s page shows 111 customer reviews, a signal of shopper interest; our recommendation comes from the actual feature set and exact tested variant rather than review count alone.
The GMT hand gives the bezel a practical job.
BODERRY identifies the movement as a TMI NH34 GMT and lists a four-hand display with calendar and hacking. The additional 24-hour hand can keep a second time reference while the main hands show local time; the numbered bezel adds another way to orient that scale. We would choose this watch for frequent travel or regular remote coordination, not as a decorative red-and-black diver alone.
Titanium keeps the full bracelet package to 117 g.
BODERRY lists a solid titanium case and five-link bracelet, anti-reflective sapphire and an aluminum bezel. At 117 g, the watch gives you a substantial metal bracelet without the weight of a similar steel build. The matching star engraving on the caseback reinforces the nautical theme and is worth seeing in the official detail photo.
The manufacturer rating and dive certification are different questions.
BODERRY lists 20 ATM / 200 m, a screw-down crown and sapphire, which is a strong published water-resistance specification for an everyday sports watch. The product information we checked does not state an ISO 6425 certification. We would follow the brand’s instructions and select a certified dive instrument when a formal standard matters.

Before you choose
A 49 mm lug-to-lug span and 13 mm thickness make the 40 mm case less compact than its diameter suggests. BODERRY lists 20 ATM / 200 m, but the page we checked does not identify an ISO 6425 certification. Treat the water figure as the manufacturer’s rating and choose a specifically certified dive watch if that is the requirement.
Who it suits.
A traveler who wants a mechanical GMT, titanium bracelet and a high manufacturer-listed water rating in a single sporty watch.
When to choose something else.
Choose a shorter case if the 49 mm span overhangs, or an ISO-certified dive watch if your purchase depends on a documented scuba standard.
Warranty, returns and ownership.
BODERRY lists a 24-month warranty for the internal movement and a 30-day return period only for eligible watches that have not been used, worn or strapped on. Free shipping is listed for most countries, but local taxes and import fees may remain payable. Check the full terms and delivered cost before ordering.
