Introduced in 2002, this timepiece was designed to cater to those who appreciate the sophistication of dress watches and the ruggedness of sports watches. The stunning champagne dial beautifully contrasts with stainless steel and yellow gold elements, creating a sophisticated look that's hard to ignore. This watch feels like wearing a piece of art on your wrist, thanks to its exquisite design, reliable movement, and robust water resistance.
