Gerald Genta is the designer's designer — the man behind the Nautilus, the Royal Oak, and the Géfica, whose own eponymous brand became a playground for horological audacity. The Bi-Retro is among his most theatrical creations: a watch that refuses the conventional sweep of hands in favour of a jumping hour, a retrograde minute, and a retrograde date. Time told differently, by someone who saw no reason to do it any other way.

Reference G3734 houses this complication in an 18k yellow gold case, paired with one of the most arresting dial choices in the collection — a Tahitian mother-of-pearl guilloché surface that shifts between deep greens, greys, and iridescent blues depending on the light. The combination of warm gold and cool iridescence is quietly spectacular.

The movement is confirmed original and fully functional, with the jumping hour, retrograde minute, and retrograde date all operating as intended — no small thing on a complication of this complexity.

Presented in top condition with its original buckle. A Gerald Genta in full voice: inventive, bold, and entirely uncompromising.
