Fratello’s July 18, 2025 roundup picked five GMT watches released in the first half of that year. The selection is an editorial shortlist, not a universal ranking: it ranges from steel dive watches to an Everose gold Rolex and a watch with an oil-filled orbital display. Here’s how the five differ in size, travel-time display, movement, and the prices Fratello reported at the time.
What Fratello’s list does—and doesn’t—represent
Watch journalist Jorg Weppelink presented these as five favorites among the releases the Fratello writers had seen up close. They are not five directly equivalent watches: the Doxa and Seiko are dive-oriented steel models, the Rolex is a precious-metal stone-dial variation, and the Ressence takes a distinctly unconventional approach to displaying time. Specifications and prices below are those reported in Fratello’s July 18, 2025 article, not verified current listings or prices.

| Ressence Type 7 | Case dimensions and water resistance not stated | Oil-filled orbital display includes a second-time-zone indicator | Automatic, manually wound; 28,800 vph; 36 hours | CHF 36,000 excluding VAT |
“Not stated” means Fratello’s available article excerpt did not provide the detail; it should not be read as a claim that the watch lacks that feature.
The five watches, and what sets each apart
Doxa SUB 250T GMT: compact dive-watch proportions and a caller-style GMT
The SUB 250T GMT pairs a 40 mm steel case with a 10.85 mm thickness and a 42.9 mm lug-to-lug measurement. Fratello reports 250 m water resistance. Its skeletonized GMT hand points to a 24-hour scale on the rehaut, while a separate adjustment lets the wearer move the 24-hour hand independently. That caller-style arrangement is useful for tracking another time zone while keeping the local hour hand in place; it differs from a traveler-style GMT, where the local hour hand is typically the independently adjustable hand.

#1 Best Overall
- BLUE DIAL: this handsome men’s watch features a striking deep blue dial with luminous dial indicator hands and markers and date calendar to keep you organized
- BLUE & BLACK BEZEL: with a 24-hour bezel and easy-to-read fourth hand, this GMT watch helps you keep time as you travel
- DURABLE UTILITY: these versatile men’s wrist watches feature a 42.5mm stainless steel watch case and bracelet, for a classic, timeless look.
- WATER-RESISTANT: this rugged sports watch is water-resistant up to 100 meters
- 4R34 CALIBER: equipped with the reliable 4R34 caliber, these automatic watches for men ensure the most accurate in self winding timekeeping, with 41 hours of reserve power and manual winding option
Fratello lists dial colors including orange, black, silver, dark blue, yellow, turquoise, white, and green. The reported movement is a Swiss automatic caliber with a 50-hour reserve; the article says it is likely made by Sellita, so the maker should not be treated as confirmed. The article-era prices were €2,550 on rubber and €2,590 on a bracelet.
Nomos GMT: an in-house movement, with model details limited in the excerpt
For the Nomos pick, Fratello highlights the automatic DUW 3202, developed, manufactured, and assembled at Nomos’s Glashütte plant in Germany. The article reports 28,800 vibrations per hour, 37 jewels, and a 42-hour power reserve, with the movement visible through a sapphire case back.
The available excerpt does not identify the full model name or establish the case dimensions and GMT display details, so it is not possible to make a precise model-to-model comparison on those points. Fratello reported a price of €3,940 and suggested availability might be limited to Nomos boutiques; that is an article-era observation, not confirmation of present availability.
Rolex GMT-Master II “Tiger Iron”: a stone dial in Everose gold
Reference 126715CHNR is the Everose gold version highlighted in the roundup. Its “Tiger Iron” dial combines tiger’s eye, red jasper, and hematite; Fratello notes that the natural stone pattern varies from one dial to another. The article also mentions a yellow-gold model with this dial, but the listed reference is the 40 mm Everose gold watch.
Fratello reports a 12 mm thickness, 48 mm lug-to-lug, a black-and-brown Cerachrom bezel insert, and an Everose Oyster bracelet. It is powered by Rolex’s in-house caliber 3285, with a reported 70-hour reserve. The article-era price was €51,250. The dial’s individual variation makes the visual character less uniform than a standard printed or lacquered dial, while the precious-metal case and bracelet place this option in a very different category from the steel Doxa and Seiko.
Rank #2
- GMT Swiss Watch: The practical GMT function makes it possible to display two time zones simultaneously thanks to an additional hand that makes one complete revolution in 24 hours and uses a bezel graduated over 24 hours to indicate a second time zone.
- Movement: Automatic Mido Caliber 80 with Navichron balance spring which reduces magnetic interference and is remarkably robust against impacts and the effects of time. This caliber ensures exceptional autonomy of up to 80 hours.
- Water Resistance: This Swiss-made MIDO timepiece is capable of withstanding pressures of up to 20 bar (200 m/660 ft), and equipped with a screw-down crown, this watch offers optimal protection against water.
- Case Size: 44mm - Case Thickness: 13.38mm. Stainless steel case with blue ceramic bezel and Sapphire crystal with double sided anti-reflection treatment - Lug Width 22mm
- Strap: Tapered, Blue Fabric Strap with Pin Buckle
Seiko Prospex 1968 Heritage Diver’s GMT SPB509: the deepest-rated diver in the selection
The SPB509 has a 42 mm case, measures 13.3 mm thick, and spans 48.6 mm lug-to-lug. Fratello gives it a 300 m depth rating. Its blue wave-pattern dial is paired with a stainless-steel bezel and dark-blue insert; a gold GMT hand and a date at 4:30 distinguish the display.
The in-house automatic 6R54 runs at 21,600 vibrations per hour and has a reported 72-hour reserve. Like the Doxa, the Seiko uses an independently adjustable 24-hour hand, a caller-style GMT configuration. Its three-row bracelet includes a tool-less extension system. Fratello listed the SPB509 at €1,900 in July 2025; that historical price does not establish today’s retail price, stock, or availability.
Ressence Type 7: an oil-filled display with orbiting indications
The Type 7’s convex dial is filled with oil and uses orbiting displays rather than conventional fixed hands. The longer indicator shows minutes, the shorter one shows hours, another display indicates oil temperature, and a further indication tracks a second time zone. Fratello describes the patented ROCS 7 (Ressence Orbital Convex System) as being driven by the minute axle of a customized ETA movement.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which one makes sense for which kind of buyer?
- For a steel dive watch with a caller GMT: compare the Doxa’s more compact reported case measurements and 250 m water resistance with the Seiko’s larger case, 300 m depth rating, bracelet extension system, and higher reported reserve.
- For a precious-metal statement piece: the Rolex combines Everose gold with a naturally varied stone dial and a black-and-brown bezel, at a reported price well above the steel options.
- For an in-house movement in a restrained design language: the Nomos pick stands out for its Glashütte-made DUW 3202, though the available excerpt leaves the exact model name and display details unidentified.
- For a radically different way to read time: the Ressence Type 7 replaces conventional fixed hands with oil-filled orbital indications, including a second-time-zone display.
If you’re researching a specific model by name, the Seiko Prospex 1968 Heritage Diver’s GMT SPB509 is clearly identified in Fratello’s roundup. Use the reference to check current listings carefully; the article’s 2025 price is not a current quote.
