Synthesized from what Tissot Gentleman Powermatic 80 owners say — not a spec sheet.
Tissot puts it at up to 80 hours from a full wind, which it describes as enough to keep telling time accurately after three days unworn. It is a Swiss automatic, so wrist movement does the winding while the watch is being worn. The 80 hours is a fully wound maximum rather than what the watch holds after a short stint on the wrist.
No. Tissot lists T127.407.11.081.00, the 40mm Gentleman Open Heart whose grey dial it records as rhodium, as carrying a patented Nivachron balance spring, a titanium-based alloy Tissot credits with resisting the magnetic fields thrown off by phones, computers and magnetic clasps. The silicon balance spring belongs to the separate Gentleman Silicium references, which Tissot credits with greater longevity, precision and magnetic resistance.
The bracelet is the weak spot, and owners say so repeatedly. Tissot fits a grey stainless steel bracelet on 21mm lugs, closed by a butterfly clasp with push-buttons, and lists it as an interchangeable quick-release bracelet, so moving to a strap needs no tools. The complaint is that the clasp carries no micro-adjustment, which leaves the fit in whole-link steps, and some owners find the edges sharp.
Owners split on this one. Tissot lists the case at 40mm across and 11.50mm tall, on 21mm lugs. Some owners say it wears larger than the listed 40mm and moved theirs on for that reason, while others read 40mm as a touch small on a bigger wrist.
75% of 172 owners recommend it, so the dissent is a minority position. The objection that repeats is visual: those owners read the dial as plain or unexciting next to rivals they were also weighing, and a few judge it poor value for its asking price. The bracelet is the other recurring complaint.
Tissot recommends a service every four to five years at a Tissot authorized service center, and separately recommends having the water resistance checked annually. The watch carries a two-year international warranty against material and manufacturing defects present at delivery; normal wear such as a scratched crystal, and damage from misuse or from work by unauthorized hands, sits outside it.
