Named for the Swiss town where Tissot was founded in 1853, the Le Locle is the brand's most traditional automatic. A black dial carries Roman numerals around a guilloche center and a date window at 3 o'clock, all inside a slim 39.3mm stainless steel case only 9.75mm thick. The Powermatic 80 movement winds itself as you wear it and stores up to 80 hours of power, with a Nivachron balance spring for resistance to magnetism; you can watch it work through the see-through caseback. Sapphire crystal, 30 meters of water resistance, and a stainless steel bracelet with a butterfly clasp. 19mm lug width.
