Slip on a classic with a colourful twist, and enjoy the simple sophistication of a sporty chronograph with 10-bar water resistance.
The flat front surface of the octagonal bezel is polished to a hairline finish and paired with mirror-finish sides, creating a handsome textural contrast — all dressed up with a dial in a soft, yet vibrant colour to give your wrist a touch of extra style.
