Tissot Le Locle Open Heart Powermatic 80 Watch – 39.3mm Silver Dial | T0064071103302

The Tissot Le Locle Open Heart Powermatic 80 is more than a watch — it's a window into 170 years of Swiss watchmaking mastery. Designed for the man who appreciates mechanical artistry, the open heart aperture transforms the dial into a stage for the Powermatic 80 calibre performing beneath the crystal.

Open Heart — The Art of Transparency

At 9 o'clock, a beautifully finished open heart aperture reveals the oscillating balance wheel of the movement — a feature once reserved for grand complications, now brought to life in this distinguished everyday timepiece. The silver guilloche dial frames this window with characteristic Swiss refinement.

Powermatic 80 — 80 Hours of Precision

The Tissot Calibre Powermatic 80 is a benchmark in its class, delivering an extraordinary 80-hour power reserve — enough to keep running through the weekend if left unworn Friday evening. The Nivachron™ balance spring ensures resistance to magnetic fields and temperature changes for consistent timekeeping.

Crafted for Longevity

The 39.3mm polished stainless steel case is fitted with a scratch-resistant sapphire crystal on both the front and the engraved exhibition case back — a signature detail of the Le Locle line. The steel bracelet with push-button butterfly clasp offers a secure and elegant fit.
