Assembled in Switzerland over the course of nine months with over 254 different components, this timepiece is finished with a sleek sunray dial punctuated with rhodium-plated hands and indexes for exceptional clarity. The rubber-lined perforated leather strap adds a sporty element to the retro design without undermining its everyday elegance.
