Doxa SUB 250T GMT

Introduction

The Doxa SUB 250T GMT (ref. 855.10.351.10) is a watch that doesn't scream for attention — it earns it. In a market flooded with dive-GMTs from Rolex, Tudor, and Longines, Doxa offers something refreshingly different: a 40mm case, 250m of water resistance, and that unmistakable orange-accented dial that has defined the brand since the 1960s. For the young collector who wants a functional tool watch without the hype-driven premiums, this is a compelling proposition.

Let's be clear: this isn't a watch you buy to flip. The secondary market is stable, not explosive. But what you get is a genuine piece of diving history, updated with a GMT complication that makes it a true travel companion. The SUB 250T GMT is a watch for those who value substance over status — and who appreciate that a well-built Swiss watch doesn't need a crown logo to be worthy.

In this review, we'll break down the specs, movement, wrist feel, and investment potential of the Doxa SUB 250T GMT. Whether you're adding it to a rotation or considering it as a first 'real' watch, here's everything you need to know.

Manufacture History

Doxa was founded in 1889 in Le Locle, Switzerland, and quickly established itself as a maker of robust, functional timepieces. The brand gained cult status in the 1960s with the introduction of the SUB dive watch, which featured a patented unidirectional bezel and a distinctive orange dial. Today, Doxa continues to produce tool watches that honor its heritage, with the SUB 250T GMT being a modern interpretation of that classic formula.

Movement

Powering the SUB 250T GMT is the ETA 2893-2, a reliable automatic movement that has been a staple in the industry for decades. It features a 24-hour GMT hand that can be independently set, allowing you to track a second time zone. The movement operates at 28,800 vph, has 21 jewels, and offers a 42-hour power reserve. While not in-house or COSC-certified, the ETA 2893-2 is known for its robustness and ease of service. The finishing is industrial-grade, with perlage and blued screws visible through the display caseback — appropriate for a tool watch at this price point.

Specs

• Case Diameter: 40mm
• Case Thickness: 12.5mm
• Lug-to-Lug: 48mm
• Case Material: Stainless steel
• Crystal: Sapphire
• Water Resistance: 250m
• Lume: Super-LumiNova
• Bracelet/Strap: Stainless steel bracelet with folding clasp and diver's extension

Wrist Feel

On the wrist, the Doxa SUB 250T GMT is a revelation. The 40mm case diameter and 48mm lug-to-lug make it incredibly versatile — it fits comfortably on a 6.5-inch wrist without looking small, and it doesn't overwhelm a larger wrist either. The case is well-proportioned, with a slight cushion shape that harkens back to the original SUB. The weight is balanced, thanks to the steel bracelet and the relatively thin profile (12.5mm).

The bracelet is solid but not groundbreaking — it has a brushed finish and a folding clasp with a diver's extension, which is a nice touch for actual diving. The clasp is a bit utilitarian, but it gets the job done. The rubber strap option (available on other references) is more comfortable for all-day wear, but the steel bracelet gives it a more premium feel. Overall, the watch wears like a true tool watch: purposeful, comfortable, and unobtrusive.

Accuracy

Real-world accuracy for the ETA 2893-2 movement typically falls within -10 to +20 seconds per day, depending on regulation and wear. With consistent winding and a full power reserve, many owners report around -5 to +10 seconds per day. It's not COSC-certified, but for a tool watch, this level of accuracy is more than adequate. If you need better precision, a simple regulation at a watchmaker can bring it within -4/+6 seconds per day.

Occasions

The Doxa SUB 250T GMT is a versatile watch that excels in sport, daily wear, and travel scenarios. Its 250m water resistance makes it suitable for recreational diving, while the GMT function is perfect for tracking a second time zone during business trips or vacations. It's not a dress watch, but it can easily be dressed up with a leather strap for a more refined look.

Wrist Presence

4/5 — The Doxa SUB 250T GMT has a strong wrist presence thanks to its bold orange accents and distinctive bezel. It's not a wallflower, but the 40mm case keeps it from being overbearing. It's a watch that gets noticed by enthusiasts, not by the general public — which is exactly the point.

Reference Variants

The reference 855.10.351.10 features a black dial with orange accents on a stainless steel bracelet. Other variants include the orange dial (ref. 855.10.351.11) and the black dial on a rubber strap (ref. 855.10.351.12). Each offers a different aesthetic, but all share the same robust construction and movement.

Family References

The SUB 250T GMT is part of Doxa's SUB family, which includes the SUB 200, SUB 300, and SUB 300T. These models share the same design language but differ in size, water resistance, and complications.

Other Notable Models by Doxa

Beyond the SUB 250T GMT, Doxa offers the SUB 200 (a 40mm dive watch without GMT), the SUB 300T (a 42.5mm dive watch with a helium escape valve), and the SUB 600T (a larger 45mm dive watch). Each has its own character, but the SUB 250T GMT is the most travel-friendly of the bunch.

Similar Watches

If you're considering the Doxa SUB 250T GMT, you might also look at the Rolex Explorer II (ref. 216570) — the gold standard for dive-GMTs, but at a much higher price point. The Tudor Black Bay GMT offers a similar tool-watch ethos with a more refined finish. The Longines Spirit Zulu Time is a more affordable alternative with a true GMT movement, while the Seiko Prospex GMT (ref. SPB381) is a budget-friendly option with a unique design.

Homages

For those on a tighter budget, the Steinhart Ocean 39 GMT ($500) is a direct homage to the Rolex Explorer II, but with an orange GMT hand option that echoes the Doxa aesthetic. It's a solid alternative, but it lacks the heritage and build quality of the Doxa.

Investment Value

The Doxa SUB 250T GMT has an MSRP of $2,490 and a current retail price of $2,490. On the pre-owned market, prices range from $1,800 to $2,500, depending on condition and completeness. The trend is stable — this is not a watch that will skyrocket in value, but it also won't depreciate dramatically. Our hold recommendation: buy it to wear and enjoy, not as an investment. Auction history is minimal, with no major sales to report.

Service Interval

Doxa recommends servicing the SUB 250T GMT every 5 years. The approximate cost is $600 at an authorized service center, but any competent watchmaker can service the ETA movement for less. The movement is widely supported, so parts and labor are readily available.

Pros and Cons

Pros

• Unique orange accents and dial options that stand out from the crowd
• Excellent 250m water resistance for a GMT watch
• Comfortable 40mm case size that fits a wide range of wrists
• Practical GMT function with an independently adjustable 24-hour hand

Cons

• Movement is not in-house and has a modest 42-hour power reserve
• Bracelet quality and clasp feel a bit utilitarian for the price
• Limited hype means lower resale value compared to Rolex or Tudor
• No COSC certification, so accuracy can vary out of the box

Final Verdict

The Doxa SUB 250T GMT is a compelling choice for the collector who wants a functional, characterful dive-GMT without the Rolex premium. It's a tool watch that wears well, looks distinctive, and holds its value reasonably. For the trust-fund-baby who values authenticity over hype, this is a solid addition to the rotation — just don't expect it to fund your next vacation.
