Deepwater Arctic a £240 sapphire diver with a slim 11.5 mm case

What is new about the Timex Deepwater Arctic?

The Deepwater Arctic is the retro-styled branch of Timex's Deepwater dive watch family. Timex says it marks a first for the collection: Arabic numerals at the quarter hours instead of the plain baton markers used on earlier Deepwater models. It also arrives on a five-link stainless steel bracelet with quick-release spring bars and a butterfly clasp, where earlier Deepwater pieces leaned on rubber straps.

The rest of the recipe is familiar but strong for the money: a ceramic bezel insert, a sapphire crystal with anti-reflective coating, Super-LumiNova on the hands and indices, a screw-down crown, a screw-on case back and 200 m of water resistance. The bracelet version went on sale in the spring of 2026 in black, blue and a dearer two-tone finish. Independent coverage has pointed out that the dial layout borrows heavily from Omega's Planet Ocean, so expect that comparison to follow it around.

How big is it, and how will it wear?

Timex publishes a full set of dimensions, which makes it easy to judge on paper:

• Diameter: 40.5 mm
• Thickness: 11.5 mm
• Lug to lug: 47 mm
• Lug width: 20 mm
• Weight: about 136 g on the bracelet

Those are sensible numbers for a dive watch. A 47 mm lug to lug span should sit inside the edges of most wrists from around 16 cm upwards, and 11.5 mm is slim for a 200 m diver; many automatic rivals are a millimetre or more thicker. The straight lugs and crown guard keep the profile tidy rather than chunky. If you have a very small wrist, the 136 g bracelet weight is worth noting, as a full steel bracelet makes any diver feel more substantial than its diameter suggests. The 20 mm lug width means straps are cheap and easy to find if you want something lighter.

What powers it, and how accurate is it?

This is a quartz watch running on an SR626SW battery. Timex does not publish a calibre name or an accuracy figure for this model, so there is no official seconds-per-month number to quote. In practice, quartz means no winding, no need to wear it daily to keep it running and far tighter timekeeping than any affordable automatic, but you will need a battery change every few years. Because the case is screw-down and rated to 200 m, that battery swap is best done by someone who can pressure test the watch afterwards.

Is it built for real diving?

On paper, yes. The 200 m rating is backed by a screw-down crown and screw-on case back, and the ceramic bezel insert sits in a unidirectional ratcheting bezel, which is what you want for timing a dive. Sapphire is the right crystal for a watch that will be knocked about on boats and harbour walls. Timex lists the case as stainless steel, and lume covers both hands and indices.

What Timex does not claim is ISO 6425 dive watch certification, so treat it as a very capable swimming, snorkelling and holiday diver rather than a certified tool for professional use.

How does it compare with rivals at the price?

At a £240 RRP on the bracelet, the Deepwater Arctic sits in a busy part of the market. Casio's long-running Duro is far cheaper but is a 44 mm watch with mineral glass rather than sapphire, so the Timex is the more refined and more wearable option if you can stretch to it. Move up to around £380 and Orient's Mako 40 gives you an in-house automatic movement in a similar 39.9 mm size, with sapphire too; the Timex counters with quartz convenience and a ceramic bezel for roughly £140 less.

Inside Timex's own range, the newer Deepwater Arctic 200 on a rubber strap adds dégradé dials and costs £215 to £225 RRP, so check which version suits you before you buy.

What is the catch?

There are three. First, the Planet Ocean influence is obvious, and some buyers will find the design derivative. Second, there is no published accuracy spec or named calibre, which makes the movement the least characterful part of the package. Third, the bracelet versions differ slightly in price, with the two-tone at £250 RRP, so confirm the exact dial and reference you are getting.

The watch is new enough that there is not yet a body of public owner feedback to draw on, so this first look is built from Timex's published specification and independent launch coverage. If you want a sapphire, ceramic and 200 m diver that wears at a modest size and asks nothing of you beyond an occasional battery, it makes a strong case for itself.

“Sapphire, ceramic and 200 m in an 11.5 mm case is a lot of dive watch for £240.”
