Tissot T-Classic Powermatic 80 Open Heart Blue Dial 40.00 mm Automatic Watch

Tissot T-Classic Powermatic 80 Automatic Watch

The Tissot T-Classic Powermatic 80 is a 40.00 mm stainless steel automatic watch designed for men who want a casual everyday timepiece with an open-heart dial. Its blue dial and index markers sit beneath sapphire crystal with antireflective coating. The 316L stainless steel case and two-tone bracelet with deployment clasp suit daily wear and office settings.

Setting the Time and Winding the Movement

Pull the crown to the first position to wind the Powermatic 80 calibre manually if the watch has stopped, then pull further to set the time. The automatic rotor winds the mainspring during normal wrist motion. Avoid setting the date between 9 pm and 3 am to prevent damage to the calendar mechanism. The sapphire crystal resists scratches but sharp impacts can still chip the edges.

Power Reserve and Daily Accuracy

The ETA C07.601 calibre with 25 jewels delivers up to 80 hours of power reserve, so the watch keeps running through a weekend off the wrist. Under sustained daily wear the movement maintains consistent amplitude, and the 100 m water resistance handles swimming and showering without pressure loss. Regular service every three to five years preserves long-term rate stability.
