Tissot Gentleman watches

The Tissot Gentleman is an everyday watch designed to work at the office and at the weekend. It began in a 40 mm case, and Tissot later added a 38 mm version. The 38 mm and standard 40 mm automatics use the Powermatic 80 with an 80 hour power reserve, behind a see-through case back. The 38 mm and Open Heart models list a Nivachron balance spring, while other 40 mm automatics list a silicon one. All models have sapphire crystal. The current range covers 38 mm and 40 mm automatics, 40 mm quartz models in steel or titanium, an Open Heart version and 40 mm models with an 18k gold bezel.
