Doxa SUB 250T GMT: what does its owner think?

DOXA SUB 250T GMT is DOXA’s return to the GMT function in a compact, robust dive watch. The idea is genuinely appealing: take the historical SUB language—dive bezel, colorful dials, beads-of-rice bracelet, strong legibility—and add a second-time-zone read. With its 40mm steel case, stated 250-metre water resistance, Swiss automatic movement, 50-hour power reserve, and skeletonized GMT hand, the SUB 250T GMT targets both travelers and fans of iconic dive watches. It is a sports watch, but not an oversized one: it seeks balance between presence, comfort, and true functionality.

Design & readability: diving, GMT, and DOXA dials

The SUB 250T GMT keeps one of DOXA’s great signatures: an instantly recognizable read, carried by highly colorful dials and a dive bezel graduated in feet. The dial remains organized around the time, but the skeletonized GMT hand adds a second-time-zone reading without overloading the whole. That matters, because a GMT dive watch can quickly become confusing if the 24-hour indication, date, markers, and bezel compete with one another. Here, the skeletonized GMT hand preserves a useful travel function while keeping the very direct character of a SUB.

The unidirectional bezel remains essential: it reminds you the SUB 250T GMT is not only a colorful travel watch, but also a genuine diver with a simple, legible timing function. The feet scale belongs to DOXA’s visual history and gives the watch a very different character from more generic dive watches. Day to day, the feet-graduated dive bezel serves both identity and use: it gives an immediate reference, whether you are actually in the water or simply timing a short duration.

Case, bracelet/strap, and everyday comfort

The stainless-steel case offers very interesting dimensions: 40mm in diameter, 42.90mm across the case, and only 10.85mm thick. For a 250-metre GMT dive watch, that is an obvious strength, because the watch remains cuff-friendly and does not become overly bulky. The screw-down crown reinforces the aquatic vocation, while the sapphire crystal with anti-reflective coating protects readability. In real life, the 10.85mm thickness is probably one of the most important arguments: the watch keeps genuine technical capability without becoming a brick on the wrist.

Bracelet or strap choice strongly transforms the experience. On the stainless-steel beads-of-rice bracelet, the SUB 250T GMT becomes more vintage, more stable, and more coherent with DOXA heritage. On color-matched FKM rubber, it becomes sportier, lighter, and better suited to water, heat, or holidays. Both options receive a folding clasp with a ratcheting wetsuit extension, reinforcing the practical purpose. In daily wear, the beads-of-rice bracelet or FKM rubber should be chosen according to use: stability and retro charm on one side, flexibility and aquatic logic on the other.

Movement: Swiss automatic, GMT, and 50-hour reserve

The SUB 250T GMT uses a Swiss mechanical self-winding automatic movement, decorated by DOXA, with a frequency of 28,800 vibrations per hour and a stated 50-hour power reserve. That reserve is coherent for a travel and rotation watch: you can set it aside for a day, pick it up again, and remain within a reasonable comfort zone. The GMT function lets you track a second time zone, while the date adds useful information when traveling. In this architecture, the 50-hour power reserve makes the watch easier to live with than an automatic with shorter autonomy.

The movement is not presented as a high-complication showcase, and that is exactly coherent: a GMT diver should be robust, readable, and easy to set. The main value is having a versatile tool: local time, second time zone, date, and dive bezel. For upkeep, good habits remain simple: avoid unnecessary shocks, have water resistance checked if the watch often sees water, rinse after salt exposure, and do not operate the crown underwater. Over time, mechanical simplicity supports reliability, especially on a watch designed to travel and be worn without excessive worry.

Main references

DOXA SUB 250T GMT Professional 855.10.351.10 :

The Professional version is the most emblematic, because it takes up the orange color associated with DOXA’s imagery and underwater readability. On the SUB 250T GMT, this dial becomes even more interesting: it is not only a dive-watch color, but a powerful background for a GMT hand and functional scale. The 40mm steel case, 10.85mm thickness, 250-metre water resistance, and screw-down crown compose a technical yet easy-wearing watch. On beads-of-rice steel, it becomes highly heritage-driven; on orange FKM, it fully embraces its sport-and-travel side. The Professional dial remains the most instantly DOXA choice, the one that speaks fastest to fans of the brand.

DOXA SUB 250T GMT Sharkhunter :

The Sharkhunter is the most understated path in the collection, with a more discreet personality and easier daily integration. The dark dial helps bring out markers, hands, and the GMT hand, while calming the range’s highly colorful identity. It is a good option if you love the DOXA architecture—feet bezel, compact case, beads-of-rice bracelet—but do not want a watch that feels too demonstrative. The specifications remain the same: Swiss automatic movement, 50-hour reserve, 250-metre water resistance, date, and second-time-zone reading. The Sharkhunter is probably the most visually versatile, especially if the watch needs to move from office to weekend.

DOXA SUB 250T GMT Searambler :

The Searambler brings a clearer read, often dressier in DOXA terms, thanks to a silver tone that reacts strongly to light. On a GMT, this kind of dial is especially useful: it creates breathing room and makes the watch feel less like a dense dive instrument. The GMT hand and colored elements can stand out more subtly, making this version a serious candidate for urban use. On steel, the whole package becomes highly coherent, almost chic, without losing the dive bezel or 250-metre water resistance. The Searambler is the brightest and dressiest choice within the collection’s spirit.

DOXA SUB 250T GMT Caribbean :

The Caribbean plays a deep-blue register, more marine, more classic, and very natural on a GMT dive watch. It is an interesting variant because it combines two compatible worlds: sea and travel. Blue works well with the dive bezel, yet remains calmer than Professional orange or Divingstar yellow. In daily use, the Caribbean may be the most balanced option if you want a sporty watch that is not too loud, with enough color to remain distinctive. Steel or FKM options let you push it toward retro charm or holiday practicality. The Caribbean is the most obvious maritime compromise, especially for those who want a frequently wearable GMT diver.

DOXA SUB 250T GMT Divingstar :

The Divingstar is the sunniest variant, with a yellow dial that makes the watch instantly visible and more playful. This color works very well within the DOXA universe, since the brand has long embraced bold, recognizable dials. On the SUB 250T GMT, yellow gives the travel function a more summery, almost holiday-like dimension while keeping the serious technical package: steel, screw-down crown, 250 metres, Swiss automatic movement, and 50-hour reserve. You simply need to accept a strong wrist presence. The Divingstar is the most expressive choice, ideal if you enjoy watches that do not try to disappear.

DOXA SUB 250T GMT Aquamarine :

Aquamarine brings a fresher, more contemporary color that softens the SUB 250T GMT’s utilitarian character. It suits a travel watch well because it immediately evokes water, light, and warm climates, while staying more original than classic blue. This variant can be especially appealing on color-matched FKM rubber, as the whole feels coherent, light, and leisure-oriented. On steel, it gains contrast and becomes more versatile. The technical fundamentals remain unchanged, letting you choose this color without giving up use. Aquamarine is the freshest, most relaxed version, perfect for a less traditional SUB.

Conclusion

The DOXA SUB 250T GMT is a very coherent proposition: a true 250-metre diver, compact, colorful, equipped with a useful GMT function and offered on steel or FKM rubber. It keeps DOXA identity—bold dials, feet bezel, beads-of-rice bracelet—while adding welcome travel versatility. The choice mainly comes down to color and strap, because the technical base is shared. If you are looking for a watch that feels maritime, travel-ready, and easy to wear, this is a genuinely exciting option.
