Timex Deepwater Meridian 300 Titanium: $999 and a helium valve say this isn't your dad's Timex
Timex just put a $999 dive watch up for pre-order — and that sentence alone signals something has changed. The Deepwater Meridian 300 Titanium HEV Automatic marks a deliberate move away from the affordable quartz watches the brand built its reputation on, into tool-watch territory where Seiko and even entry-level Swiss names typically live. Whether the market agrees it's worth $999 is the real question.
The build
The case is Grade 5 titanium, 44mm wide and 15mm thick. Titanium is lighter than steel and genuinely corrosion-resistant in saltwater, so the material choice makes practical sense for a dive watch. A sapphire crystal with anti-reflective coating protects the dial, and the bezel insert is ceramic — hard enough to resist everyday scratching. Water resistance is rated to 300 meters, which covers recreational and technical diving well beyond what most wrists will ever see.
The headline feature is the automatic helium escape valve (HEV) at the 10 o'clock position. This lets helium gas vent safely during decompression after saturation dives — the kind of work done by professional divers living in pressurized chambers for days. For everyone else, it's a prestige detail rather than a practical necessity, but it's the same function found on Rolex Submariner and Omega Seamaster Pro models that cost multiples of this price.
Two dial options are available: a classic black with luminescent markers, and a full-coverage green dial coated entirely in Nemoto LumiNova SG2200 — the kind that glows visibly in complete darkness. Both come on an HNBR rubber strap, a synthetic material that resists UV degradation and pool chemicals.
The movement question
Inside sits a Miyota 8215, a 21-jewel Japanese automatic with a 40-plus-hour power reserve. It's a proven, serviceable workhorse used widely across the watch industry — but it lacks hacking seconds, meaning you can't stop the second hand to sync the time precisely. The competing Seiko NH35, found in many watches at this price range and below, does include that feature.
At $999, Timex is asking buyers to pay for the titanium case, the HEV, and a brand repositioning rather than a premium movement. The previous Deepwater Meridian 200 — stainless steel, 200m — sits around £215–£240 at UK retailers, which puts the titanium 300m variant in genuinely different financial territory. Pre-order is live now at Timex.com for both dial variants; UK and European pricing have not been confirmed.
