Timex Deepwater Reef 200 GMT TW2W75000 dive watch

Starting from 279 €

The Timex Deepwater Reef 200 GMT is an affordable dive watch that adds a second time zone function to the classic diver's vocabulary. Part of the Deepwater collection launched by Timex in October 2024, it combines a 41 mm steel case, a unidirectional ratcheting bezel, an anti-reflective sapphire crystal and 200 metres of water resistance rated by the brand for recreational diving. Its black dial with full hour markers, 24 hour arrow hand and magnified date window make it a legible instrument, designed as much for travel as for the water. Priced at 279 euros on a synthetic rubber strap, it targets divers and travellers looking for a rugged tool watch without breaking the bank.

Timex Deepwater Reef 200 GMT dive watch

Timex has been making watches since 1854 and built its reputation on a simple promise: put a well made instrument on the wrist without emptying the wallet. That philosophy runs through its whole history, from field watches to everyday timepieces, and remains intact in the Deepwater collection, unveiled on 10 October 2024. Three models made up the range at launch: a Deepwater Reef 200 quartz, this Deepwater Reef 200 GMT, and a Deepwater Reef 200 Titanium Automatic. All share the same technical base, with a 41 mm case borrowing its silhouette from classic divers, a unidirectional ratcheting bezel, an anti-reflective sapphire crystal, a screw-down crown and caseback, and 200 metres of water resistance.

To back up the collection's credibility, Timex highlighted a pressure test carried out with freediver Francesco Sena, who descended to 42 metres in the Y-40, the third deepest pool in the world, in Italy. The demonstration is as much symbolic as technical, but it is a reminder that the Deepwater is no fashion diver: the case construction, with its screw-down crown marked with an arrow to signal that it must be closed, firmly belongs to the tool watch family.

The GMT version holds a particular place in the range. Where the simple quartz model only tells the time, this one adds a fourth hand and a date window, aimed at travelling divers and fans of military and professional watches who appreciate an extra function without added complexity of use. Its recycled stainless steel case fits within the sustainability approach the brand has been promoting for several years.

The Timex Deepwater Reef 200 GMT dive watch in a few words

The Deepwater Reef 200 GMT takes up the silhouette of skin diver style watches, with an H shaped case whose horizontally brushed flanks are paired with polished bevels. The 41 mm recycled stainless steel case stays within a universal size, and its 13 mm thickness keeps it within a reasonable envelope for a watch rated to 200 m of water resistance. The moderate weight of 94.61 g helps balance on the wrist, especially since the rubber strap lightens the overall package compared with a steel version.

Legibility sits at the heart of the design. The black dial with full hour markers carries Super-LumiNova® on the hands and hour markers, while the anti-reflective sapphire crystal limits stray reflections underwater as well as in bright sunlight. The date window positioned at 3 o'clock is topped with a magnifying lens that enlarges the number, a rare touch at this price point, though some users report that this lens can create annoying glare depending on the angle.

The unidirectional ratcheting rotating bezel keeps its primary diving function: it is not used to read the second time zone. That role is handled by a two colour 24 hour scale printed around the minute track, a solution that leaves the bezel free for timing immersions. Together these elements form a coherent tool watch, with no decorative excess.

A dive GMT designed for travel and water

What sets this reference apart is its GMT analogue quartz movement, which drives a fourth arrow shaped hand that makes one full turn of the dial every twenty-four hours. This hand is read against the two colour 24 hour scale on the rehaut, the light section covering daytime hours and the dark section covering night-time hours. The principle is straightforward: the wearer keeps their reference time visible while setting the main display to the local time zone. Powered by an SR920SW battery, the movement requires little attention and keeps the accuracy typical of quartz, an advantage for anyone who dislikes resetting a watch after several weeks off the wrist.

On the water resistance side, the construction relies on a screw-down crown and a screw-down caseback, the crown bearing an engraved arrow reminding the wearer to close it before diving. Timex places the watch in the recreational diving category, confirmed by the 120-click unidirectional bezel fitted with a luminous pip at the zero marker.

The black embossed HNBR synthetic rubber strap closes with a slip-thru buckle that hides excess material, and adjusts to wrist sizes from 142 to 205 mm. The 22 mm lugs open up a wide range of replacement options, a welcome way out for anyone who finds the raised logo on the strap too visible.

Timex Deepwater Reef 200 GMT dive watch: ruggedness and dual time zone

The Timex Deepwater Reef 200 GMT brings together a 41 mm recycled stainless steel case, 13 mm thick, an anti-reflective sapphire crystal and 200 metres of water resistance reinforced by a screw-down crown and caseback. Its GMT analogue quartz movement drives a 24 hour arrow hand read against a two colour scale printed around the dial's rim, leaving the unidirectional ratcheting rotating bezel dedicated to timing dives. The black dial with full hour markers carries Super-LumiNova® and a date at 3 o'clock enlarged by a magnifying lens. The 22 mm black HNBR synthetic rubber strap completes this tool watch priced at 279 euros.

01

Movement

The watch is driven by a GMT analogue quartz movement that tracks two time zones simultaneously. An additional 24 hour arrow hand makes one full turn of the dial every day and is read against the two colour scale printed around the minute track. Power comes from an SR920SW battery, promising long autonomy and minimal upkeep. Timex does not disclose the calibre reference used, which remains common at this price point, but the accuracy typical of quartz remains the main selling point.

Diameter and materials

The 41 mm recycled stainless steel case adopts a skin diver architecture, with a brushed finish highlighted by polished bevels. Its 13 mm thickness and weight of 94.61 g remain contained for a diver of this category. The black dial with full hour markers carries hands and markers coated in Super-LumiNova®. Above, an anti-reflective sapphire crystal protects the display and incorporates a magnifying lens placed over the date window, while the unidirectional ratcheting rotating bezel frames the whole.

Water resistance

The 200 m / 20 ATM water resistance places this Deepwater in the recreational diving category, a use explicitly claimed by the brand. This resistance relies on a screw-down crown, marked with an arrow reminding the wearer to close it, and a screw-down caseback. The 120-click unidirectional bezel has a luminous pip at the zero marker for tracking dive time. The Deepwater collection was also tested during a descent to 42 metres in the Y-40, in Italy.

Accessories

The watch comes on a black embossed HNBR synthetic rubber strap, moulded in one piece for durability and comfort. Its slip-thru buckle closure retains excess material, and it adjusts to wrist sizes from 142 to 205 mm. The 22 mm lugs make it easy to swap on a steel bracelet, a Nato strap or a rubber strap from another supplier. Timex does not detail the box contents, but provides a PDF user manual on its website.

A purchase made on timex.eu qualifies for a 2 year warranty, while the international warranty covers 1 year. Coverage applies to defects found in the movement, crystal, strap and case, with the battery explicitly excluded from claims. Timex also offers a repair service accessible from its dedicated portal.
