Think of this Tissot Gentleman as a dress watch that refuses to be fragile. The green-dial T127.407.11.091.01 has the polish and proportions of a formal piece, yet it is rated to 100 meters and built around a movement designed to stay accurate in a world full of magnets.

That movement is the Powermatic 80 Silicium. Its balance spring is made of silicon rather than a traditional alloy, which makes it resistant to the everyday magnetic fields that can disturb a conventional hairspring. The result is an automatic that stays consistent, with up to 80 hours of autonomy when it is off the wrist.

On the outside, Tissot plays green against steel. Sunlight warms the dial toward emerald while indoor light deepens it to forest, and the alternating brushed and polished links of the bracelet echo the finishing on the 40mm case. A butterfly clasp with push-buttons keeps it secure and easy to take on and off.
