T139.407.11.068.00 Named after the street leading to the home of Tissot in the Swiss mountains, the Chemin des Tourelles collection is one of the icons of the brand: round, classic, mechanical, timeless. Now updated and refined, this edition features a gently domed sapphire crystal that sits over a dark grey sunray dial with simple, elegant baton hour markers, each faceted to catch the light in an understated but sophisticated way. Nestled at the heart of this 42mm watch is our Nivachron Powermatic 80 movement, a state-of-the art automatic mechanical movement with an 80-hour power reserve and elevated anti-magnetism.
