At the heart of this watch lies the IWC-manufactured 52615 calibre. This movement is a work of art, visible through the sapphire glass exhibition caseback. It features the legendary Pellaton winding system, which has been updated with black and white ceramic components to virtually eliminate wear. The movement utilizes two barrels to achieve a 7-day power reserve, ensuring the perpetual calendar remains synchronized even if the watch is taken off for several days.
The dial of the Ref. IW503605 is a masterclass in information density and clarity. It displays the date, day, month, year in four digits, and a perpetual moon phase. Most notably, the “Double Moon” display shows the moon’s phase as seen from both the Northern and Southern hemispheres simultaneously—a feature accurate to within one day every 577.5 years. All these displays are perfectly synchronized and can be advanced simply by using the single conical crown, a testament to the user-centric engineering of IWC.
The 46.2mm stainless steel case is balanced by a premium blue alligator leather strap with a stainless steel folding clasp, providing a secure and comfortable fit despite its bold dimensions. The sunray-finished blue dial catches the light beautifully, shifting from a bright cobalt to a deep navy depending on the angle. For the collector who demands the history of the “Grosse Fliegeruhr” paired with the most sophisticated mechanical calendar in the world, the IW503605 is an unrivaled choice.
