Tissot PRX Powermatic 80 Dress Watch
The Tissot PRX T-Classic Powermatic 80 is a stainless steel dress watch for men who want an automatic timepiece with a 40.00 mm case and integrated bracelet. Its silver dial uses index markers and a date window at three o'clock. The 316L case and sapphire crystal with anti-reflective coating suit daily professional wear. Buyers needing a diver's bezel or chronograph function should look elsewhere.
Thermals Noise and Power in Daily Wear
An automatic movement requires no battery and produces no heat or audible noise during normal use. The Powermatic 80.111 calibre runs at a relaxed frequency and stores up to 80 hours of power reserve from wrist motion alone. Water resistance is rated to 100 metres for swimming and showering. The deployment clasp secures the bracelet without tools.
Behaviour Under Sustained Activity
Continuous arm movement keeps the mainspring wound so the watch maintains its power reserve through long days. The 23 jewels reduce friction in the gear train for consistent timekeeping over extended periods. Sapphire crystal resists scratches that accumulate with daily contact. The fixed bezel and pull/push crown preserve the 100 metre seal during prolonged exposure to water.

Questions about this item
How do I size the stainless-steel bracelet and what step is often missed?
Remove links to fit the wrist, then ensure the deployment clasp clicks fully closed on both sides; an unlatched side can spring open.
What service will the Powermatic 80.111 movement need over time?
A full service every 3–5 years: clean, lubricate, replace gaskets, and test 100 m water resistance and the 80-hour power reserve.
Which limit appears first during continuous wear?
The 80-hour power reserve runs down if the watch stays off the wrist for more than about three days.
