Harry Winston Ocean Biretrograde Automatic 36mm

The Harry Winston Ocean collection, which celebrated its 20th anniversary in 2018, now welcomes two Biretrograde models into this sporty yet elegant watch family. In these new versions, shimmering mother-of-pearl dials mingle with round brilliant diamonds in an 18-karat white or rose gold case.

True to their heritage, the timepieces bear two hallmark Ocean complications: excentered hours and a double retrograde display. The hours and minutes counter dominates the top half of the dial, while the retrograde days of the week are at 4 o’clock and the retrograde seconds counter is at 8 o’clock.

The beauty of biretrograde displays lies in the opposing choreography of the hands; the day-of the-week hand and the seconds hand advance in opposite directions. The retrograde seconds hand is in constant motion, tracing the 30-second track before jumping back, counter-clockwise, to zero. The hand indicating the day of the week advances every 24 hours and performs its sweeping jump on Sunday at midnight. For increased functionality, a date window sits at 6 o’clock under a magnifying lens.

The background of the dial features natural mother-of-pearl. Glowing with its signature iridescence, the nacre shines in all four counters. A total of 99 brilliant-cut diamonds highlight the counters, while an emerald-cut diamond, Mr. Winston’s favorite shape, crowns the hours.

The luxurious 36mm gold cases with their distinctive arches at the crown – a tribute to the doorway of Harry Winston’s Fifth Avenue Flagship Salon – are set with the sparkle of 57 brilliant-cut diamonds.

The Ocean Biretrograde timepieces are equipped with a Swiss automatic movement featuring a balance spring made from silicon. The automatic movement with its skeletonized rose gold rotor and circular Côtes de Genève decoration on the bridges can be admired through the sapphire crystal case back.

The rose gold model is fitted with a pearly beige alligator strap, while the white gold model features a pearly white strap. Both timepieces are secured to the wrist with a gold ardillon buckle set with 42 brilliant-cut diamonds.

Designed for everyday wear, these glamorous yet versatile timepieces are water resistant up to 100 meters.
