This DB15ST is my latest acquisition during my recent trip to Japan. A perpetual calendar with 3-D spherical moonphase at 12. The dial is much easier to read than most of the perpetuals out there. The leap year is indicated by the changing of the color of the star under the globe, depending on the year. Handwound with 4 days power reserve. The DB15 is produced entirely in DB's manufacture and houses the caliber 30 with double barrel.
