The 42mm version of the watch has a more sophisticated and elegant look, designed to appeal to all, and will look good at an elegant event, in the office, or while playing sports. It has a thinner case, with ergonomic steel pushers, a thin bezel and a bracelet fully integrated into the design. Strikingly different from the 45mm model, it is built for customers who demand streamlined elegance as well as the latest wellness and sport functions. Straps and Bracelets Customers can now opt for a large variety of straps, including a leather or steel strap for a more refined, elegant look. For a more sporty, rugged feel, customers can opt for multi-coloured rubber straps.
