It is a big caliber, and the watch got even bigger than the standard 6104 Celestial, but that caliber is hidden behind a closed caseback. Now 3mm wider, the Celestial Sunrise and Sunset measures 47mm by 12.19mm (actually quite a reasonable thickness) and emphasizes the flying saucer shape with a lugless design and black, vulcanized polymer strap with X-shaped decorative motifs and the brand’s patented triple-blade double-security fold-over clasp in 18K white gold. Since there are no lugs, there’s no lug width listed. And yet, surprisingly, the brand decided to share that the strap measures 31mm at its widest point. An interesting fact!
The already complex Celestial display now looks even fuller, and yet somehow seems readable in pictures. Hours, minutes, seconds, pointer date, the rotating circle highlighting the celestial vault—all of those make sense. Two oval cams inside the movement rotate throughout the year, representing the Earth’s tilt on its axis, and a feeler spindle reads these and, through a number of other parts, turns them into the sunrise and sunset times. That, creatively, is represented on the same scale used for the date (which is boldly indicated with a red hand). By using push pieces hidden in the case, you can change daylight saving time (which then moves the date disc to adjust the scale back or forward, rather than adjusting the hands). The date adjusts itself during that switch as well.
