Genta, was deeply involved in the mechanics of his timepieces from his early days at Universal Geneve. He introduced the retrograde minute, a jump hour movement, and later a retrograde date, which redefined the way time is displayed on a watch. The Biretro complication from Genta, featuring a retrograde date and minute combined in a jump hour movement, is a reinterpretation of time. On a normal watch, seconds, minutes, and hours move in a circular fashion, while on a jump hour and retrograde minute watch, each hour forms its own entity, a digital unit detached from previous events and future events. This design maintains its independence from the moment, ensuring a unique and immersive experience for the wearer.
This specific example isn't an easy model to find, especially with its original box and papers. The blue dial is amazing, it's the perfect shade of royal blue. The white hands and numbers make the watch very easy to read. Paired with the original blue box, you have an amazing set.
