Calendrier Perpetuel DB17De Bethune presents a new version of the perpetual calendar with moon-phase indication and eight-day power reserve. The original indication of the moon at 12 o’clock is composed of a platinum and blued steel sphere emerging from a subdial and spinning on its own axis. Created on a solid gold plate, engine-turned by hand with a sunray motif, the dial features month and day indications at 3 and 9 o’clock respectively, while the date appears on a raised circle at 6 o’clock.
