Pale blue leather and a white dial give this 34mm Tissot Chemin des Tourelles a fresh, springtime lightness that is hard to find in mechanical watches of this quality. It is an automatic that feels as much like an accessory as an instrument, and it looks especially good with linen, denim and summer whites.

The white dial has a soft sunray finish and faceted baton markers that pick up light from every angle, while the date sits discreetly at six o’clock. A gently domed sapphire crystal sweeps over the top, echoing the rounded, vintage-inspired lines of the 34mm steel case.

Inside is the Swiss Powermatic 80, an automatic caliber with a Nivachron balance spring and up to 80 hours of power reserve. Its rotor is on view through the transparent caseback. The name honors the Le Locle street where Tissot’s factory opened in 1907, and the watch is water resistant to 50 meters.
