2026 IWC Big Pilot's Watch Perpetual Calendar Ceralume IW505801

The IWC Big Pilot's Watch Perpetual Calendar Ceralume (Ref. IW505801) marks the brand's first Big Pilot's Watch featuring a perpetual calendar and Ceralume® luminous ceramic. Developed over years of dedicated research by IWC's XPL experimental engineering division, this innovation has now been granted patent certification. The material is created by thoroughly blending ceramic powder with luminescent pigments and firing the mixture using a proprietary ball-milling process, resulting in a uniform, deep blue glow in the dark.

Conventional luminous watches are typically crafted using composite materials or surface-applied luminous paint; consequently, this Ceralume® monobloc luminous ceramic timepiece is exceptionally rare. Its luminosity is intense enough to illuminate the back of the wearer's hand, ensuring clear and intuitive legibility at night. Buy top IWC clone watches online, buy replica watches at twatchclone。

The 2026 IWC Big Pilot's Watch Perpetual Calendar Ceralume (Ref. IW505801) utilizes IWC's classic single-crown perpetual calendar adjustment mechanism: the 12 o'clock position features a dual-hemisphere moon phase display; the 3 o'clock position displays the date on the outer ring and the power reserve on the inner ring; the 6 o'clock position indicates the month; and the 9 o'clock position displays the day of the week on the outer ring and the small seconds on the inner sub-dial. Powered by the IWC Calibre 52616, the timepiece is equipped with the classic Pellaton bi-directional automatic winding system (known as the "woodpecker" winding mechanism), a twin-barrel design, and boasts a power reserve of up to 7 days.
