The Tissot PRX Titanium 38mm weighs 84g, according to Tissot’s specification and T3’s week-long review. Its case and bracelet are titanium, while the bezel is stainless steel. That precise mix—and how the watch feels in daily wear—matters more than a broad claim that titanium makes every part feather-light.
What the week on the wrist revealed
In his 22 September 2026 T3 review, Alistair Charlton wore the anthracite-dial PRX Titanium for a week and reported that its low weight was easy to forget. He also found that the 38mm integrated-bracelet design had more wrist presence than the diameter alone might suggest, while sitting close to the wrist. Those are one reviewer’s impressions, not a fit guarantee for every wrist. Read Charlton’s T3 review.
The experience is a useful counterpoint to sizing by diameter alone: the PRX’s integrated bracelet and case shape contribute to how it looks and wears. Fratello reviewer Jorg Weppelink, who owns the 40mm PRX and has an 18.5cm wrist, described 38mm as a useful middle size. He saw it as a potential option for people choosing between the 35mm and 40mm versions. Read Weppelink’s Fratello review.

Tissot specifies titanium for both the case and bracelet, but stainless steel for the bezel. Calling it a titanium-case-and-bracelet watch is accurate; describing the whole exterior as titanium is not. The official US listing gives the reference as T137.807.44.061.00 and lists its weight as 84.00g. See Tissot’s US product listing.
#1 Best Overall
- Case Size: 38.00 mm, Band Width: 25mm, Case Thickness: 10.98 mm
- Automatic movement, leather strap, Index dial type, Date
- Water-resistant up to a pressure of 10 bar (100 m / 300 ft): suitable for short periods of recreational swimming and showering, but no diving or snorkeling.
The 84g figure is confirmed independently in Charlton’s T3 review, which reports that weight for the watch he wore. The sources do not provide a directly comparable weight for a steel PRX, so there is no sound basis here for calculating a percentage weight saving or claiming a specific gram difference from the 40mm steel model.

How it compares with other PRX sizes and finishes
The titanium PRX occupies the 38mm position between the 35mm and 40mm models, but size is only one distinction. The reviewed 38mm titanium watch combines a lighter listed weight with titanium case and bracelet construction, while the 40mm steel PRX is the price reference in T3’s comparison. No comparable steel-model weight is given in the cited reviews.

Fratello’s November 2025 review describes an anthracite dial with rose-tone details and a dark-blue option with nickel-plated hands and markers. T3’s 2026 week-on-the-wrist article concerns the anthracite version. Dial options and local stock can change, so check the current listing for the market where you plan to buy.
Rank #3
- Case Size: 40.00 millimeter; Band Width: 12 millimeter; Case Thickness: 10.40 millimeter

- Stainless steel bracelet, butterfly clasp with push-buttons closure

Another nearby option mentioned by T3 is the 38mm Damascus-steel PRX. Its case material and price differ from the titanium model; it should not be treated as another dial variant of the same lightweight configuration.
