A fun as hell watch from one of the world's most famous and successful watchmaker/designers, Gerald Genta. The Arena Bi-Retro offers the hours in an aperture which jumps in concert with the retrograding minute hand. Down below is a date indication which also retrogrades back to the 1st at the last moment of the 31st day.
Furnished w/ original Gerald Genta box, no papers. The steel bracelet is sized to 7.25" but with the extra links can easily accommodate an 8" wrist. Approximate date from my googles appears to be mid-2000s.
