- How long does the power reserve last?
- About 80 hours, roughly three days, once fully wound. That covers a weekend off the wrist.
- Can I swim with it?
- Yes. It is rated to 10 ATM (100 m), which covers swimming and showering. The crown is not screw-down, so avoid diving.
- Can I change the strap?
- The bracelet is integrated into the case, so standard straps do not fit. Tissot sells its own rubber strap for this model.
- Is the crystal scratch-resistant?
- Yes, it uses sapphire crystal, which resists everyday scratches far better than mineral glass.
- Does it have a date?
- Yes, there is a date window at 3 o'clock. The dial uses applied index markers rather than numerals.
- How does it compare with the quartz PRX?
- The Powermatic 80 is thicker and heavier but adds an automatic movement and the long power reserve. The quartz version is slimmer and needs a battery change every few years.
