Profound Universe

75th anniversary limited model
The dial design, inspired by the Perseid meteor shower and featuring a cutting-edge skeleton movement with new meteorite-like finish, awakens a romantic fascination and intellectual curiosity about the universe.
The ring-shaped openwork dial with Roman numerals and indices features a new black and grey gradation with matte finish.
Distinctive two-tone design

The ring-shaped openwork dial with Roman numerals and indices features a new black and grey gradation with matte finish. These black elements expressing the darkness of outer space provide a point of contrast to the bright steel-coloured bezel, caseback and crown, further accentuating the watch’s design.
Meteorite-style finished movement

Based on hand winding calibre F8B61 – which features a silicon escape wheel with state-of-the-art MEMS technology, high accuracy of +15 to –5 seconds per day, and power reserve of 70 hours – the new calibre F8B65 builds on this foundation with a new meteorite-like finish on the dial and caseback, achieved through advanced laser processing technology, to create an intricate crystalline pattern that gives the impression of an actual meteorite being integrated into the watch.
