Tissot PRX CarbonThis model takes the PRX design to a lighter and sportier level with a 40,5mm forged carbon case, weighing 75 grams, a black carbon dial, a synthetic strap, and a Powermatic 80 movement with an 80-hour power reserve. Unlike the steel PRX with its integrated bracelet, the aim here is to give a more technical and comfortable everyday wear feel.
What kind of watch is the Tissot PRX Carbon?
The PRX Carbon is the forged carbon case version of the Tissot PRX family. According to Tissot's official specifications, the case material is black-grey marble-look forged carbon and a black PVD-coated 316L steel case back. Because of this construction, each case doesn't have an identical texture; the forged carbon character adds a visually distinctive touch to the model.
This model is lighter than the classic steel PRX. The official weight is 75 grams. This difference is particularly noticeable for extended daily use. For users who love the PRX form factor but don't want the weight of a steel bracelet, the Carbon version is a sensible alternative.

Case, Dial and Strap
The watch measures 40,5 mm in width, 40 mm in length, and 11,23 mm in thickness. The case shape retains the tonneau design of the PRX. The sapphire crystal features an anti-reflective coating. The dial color is officially listed as black carbon in the technical specifications.
The strap is synthetic and features a quick-change system. This choice gives the PRX Carbon a sportier look. Instead of the integrated ring feel of the steel PRX, here it offers a lighter, more casual, and more technical feel.
Powermatic 80 and Silicone Balancing Spring
The PRX Carbon uses the Swiss automatic Powermatic 80 movement. Tissot's official website specifies a silicon balance spring for this model. A power reserve of up to 80 hours increases the likelihood of finding the watch still working even if you haven't worn it for several days.

Should I buy the Tissot PRX Carbon?
The Tissot PRX Carbon is a good option for those who love the classic PRX design but want a lighter, darker, and more sporty watch. For someone seeking the iconic feel of the steel-bracelet PRX, the Carbon might be too casual. However, if lightness, the forged carbon look, and the Powermatic 80 movement are priorities, the model is quite appealing.
