Developed during the 1980s, IWC’s legendary perpetual calendar automatically recognizes the different lengths of the months and leap years. The timepiece is powered by the IWC-manufactured 52615 caliber, which can be observed through the sapphire glass case back.

In 2022, IWC unveiled its “Colors of TOP GUN” collection comprising various Pilot’s Watches in striking new ceramic colors. With the Big Pilot’s Watch Perpetual Calendar TOP GUN Lake Tahoe (Ref. IW503008), the Swiss luxury watch manufacturer now adds another model in white ceramic to the line-up. The ceramic color, which IWC and Pantone have specified as “IWC Lake Tahoe”, is inspired by white uniforms and the winter landscape around freshwater Lake Tahoe. Located between California and Nevada, Lake Tahoe is a mountainous area that the pilots of the nearby TOPGUN flight school frequently fly over. The eye-catching design is completed with a pitch-black dial and black hands with white Super-LumiNova®, a stainless steel crown and case back ring, and a white textured rubber strap.


White ceramics are emblematic of IWC’s comprehensive expertise in advanced performance materials. The company experimented with this color as early as the 1980s, shortly after introducing its first wristwatch with a black zirconium oxide ceramic case. White ceramic is created in a complex manufacturing process in which zirconium oxide is mixed with other metallic oxides and sintered at high temperatures in an oven. Ceramic is extremely scratch-resistant and remarkably light, making it the perfect material for a Pilot’s Watch.


The Big Pilot’s Watch Perpetual Calendar TOP GUN Lake Tahoe features the legendary perpetual calendar complication. It was developed in the 1980s by Kurt Klaus and since then, it has been steadily improved several times in terms of mechanics and functionality. The intricate mechanical program automatically recognizes the different lengths of the months and leap years and will require no manual adjustment until 2100. The patented double moon phase display shows the moon as seen from the northern and southern hemispheres. Thanks to a special reductionist gear train, it is so precise that it will only deviate by one day after 577.5 years. The calendar module is driven via a single nightly switching impulse by the IWC manufactured 52615 caliber movement with a Pellaton winding system and a power reserve of 7 days. The movement can be admired through a transparent sapphire glass back.

The Big Pilot’s Watch Perpetual Calendar TOP GUN Lake Tahoe will be available as of July 2023. In addition, the timepiece is eligible for registration under the My IWC care program and can benefit from a 6-year extension to the standard 2-year International Limited Warranty.
