The Tissot Le Locle automatic watches form a range that is as rich as it is beautiful. A truly historic timepiece, it embodies the spirit of innovation that has defined Tissot for over a century. This model has a blue dial, with diamonds inlaid for the hour markers. This model features a patented Nivachron™ balance spring, which significantly attenuates the effects of magnetic fields while resisting shocks, ageing and temperature variations. It also features a date function and a transparent caseback allowing its internal mechanics to be admired. The leather strap has a butterfly clasp with push buttons. It is interchangeable and easy to open.
