Gentleman Powermatic 80 Open Heart This men's watch is part of the T-Classic series. This line consists - as the name suggests - of watches with a classic twist. This Tissot Tradition model has a vintage look, with a 1950s style case. The watch has a special automatic movement, namely the Powermatic 80. This timepiece has a power reserve of no less than 80 hours! Furthermore, the luxury watch has a sapphire glass, folding clasp and is waterproof up to 100 meters. In addition to the time, the dark blue dial also shows part of the movement, the so-called 'Open Heart'. Finally, the model is equipped with a steel watch case. Perfect for men who are looking for a unique watch with a classic look. Powermatic 80 Tissot uses the ETA C07.811, better known as Powermatic 80, in the version with a silicon balance spring. This spring has a longer lifespan, greater precision and is better resistant to magnetic fields. The self-winding timepiece has a handy 80-hour battery reserve, hence its name. With more than three days of runtime when not worn, the Tissot Gentleman ensures its owner gets through the weekend without having to rewind his watch or reset the time.Right of withdrawal Are you choosing a size other than the standard size specified?
