Timex is making a more serious move into mechanical dive watches with the Deepwater Meridian 300 Titanium HEV Automatic. The model is designed as a tool watch first, and it marks a clear departure from the brand’s long-standing image of inexpensive quartz models.
The most important shift is not cosmetic. Timex has built the watch around materials and specifications that matter underwater, starting with a Grade 5 titanium case that keeps the weight lower than steel while still supporting a large dive-watch form factor.
Built for Depth, Not Display
The Deepwater Meridian 300 measures 44 mm across, with a 15 mm thickness and a 51 mm lug-to-lug length. Its unidirectional rotating bezel uses a ceramic insert, while the sapphire crystal comes with an anti-reflective coating for better legibility.
According to Gizmochina, the case uses a matte bead-blasted finish that reinforces the watch’s utilitarian look. Timex also adds a screw-down crown, an integrated crown guard, and a threaded screw-down case back to match the demands of a serious dive watch.
The water resistance rating reaches 300 meters, and the model includes an automatic helium escape valve on the case side at the 10 o’clock position. That feature is aimed at saturation diving, where helium can build up inside the case and must be released safely during decompression.
| Case Specification | Detail |
|---|---|
| Case size | 44 mm |
| Thickness | 15 mm |
| Lug-to-lug | 51 mm |
| Case material | Grade 5 titanium |
| Bezel | Unidirectional rotating bezel with ceramic insert |
| Crystal | Sapphire crystal with anti-reflective coating |
Two Dial Options, One Practical Focus
Inside the titanium case, Timex uses the Miyota 8215 automatic movement. The 21-jewel Japanese caliber is powered by wrist motion, offers up to 40 hours of power reserve, and can also be hand-wound through the crown after a longer stop.
The brand offers two dial versions. One uses a black dial with luminous hour markers, while the other comes with a green dial coated across its surface with Japanese Nemoto LumiNova SG2200 for low-light visibility.
| Dial Variant | Main Characteristic | Purpose |
|---|---|---|
| Black | Luminous indexes | Classic dive-watch appearance |
| Green | Full Nemoto LumiNova SG2200 coating | Designed for visibility in dark conditions |
Both versions are paired with a black 20 mm HNBR strap. The Hydrogenated Nitrile Butadiene Rubber material is chosen for resistance to UV, heat, and chemical exposure, while the perforated design helps with ventilation and water drainage.
Timex also includes quick-release spring bars, making strap changes easier without tools. That detail keeps the watch focused on utility rather than presentation.
Price and Availability
The Timex Deepwater Meridian 300 Titanium HEV Automatic is currently listed for pre-order in the United States. The listed price is $999.
The launch also shows that Timex is pushing further into the mechanical dive-watch segment. At the same time, the company has also introduced the 1981 Reissue, which brings an ice blue dial and a more compact 35 mm case.
With titanium construction, 300-meter water resistance, a helium escape valve, and the Miyota 8215 movement, the Deepwater Meridian 300 stands out as one of the most serious dive watches Timex has released. It is clearly aimed at buyers who want a fully specified tool watch with a functional, restrained design.
