The Mondaine Helvetica No1 Bleu Marine features in the Light style and is distinguished by an exquisitely matched navy leather strap that has been updated to a ‘light look’ with tiny stitching for the Light collection and with a slightly more paddled detail for the Regular. The Mondaine Helvetica No1 Light Bleu Marine model also features a gold-plated version, which looks stunning against the navy leather strap with polished dimensions.
