The Royal Oak Perpetual Calendar watch, with its elegant blue dial and sophisticated stainless steel case, perfectly embodies both aesthetic design and advanced technical complexity.
The case is made of 3161 stainless steel, 41mm in diameter and 11.4mm thick. The blue dial features a large "grande tapisserie" pattern, applied hour markers, and faceted hands coated with luminescent material. Three sub-dials display the date: hour, minute, day of the week, date, month, moon phase, and country/year information. Sapphire crystal with anti-reflective coating enhances the watch's clarity and brilliance.
