As well as being Harry Winston's sport watch range, Ocean is also a showcase for selected complications. This latest model comes with two of the brand's characteristic features: a retrograde display - one for the seconds and one for the day -, and an off-centre hours and minutes subdial. Water-resistant to 100 metres for everyday wear, the two limited editions – one in white gold and one in pink gold – confirm Harry Winston's passion for beautiful gems. Another distinctive feature is the dusting of ruthenium crystals on the dial. A first in watchmaking, they lend sparkle, texture and depth to the surface. Both models are driven by an automatic movement with a silicon balance spring, delivering 65 hours of power reserve.
