IWC - Big Pilot’s Watch Perpetual Calendar Edition Racing Green IW503005

IWC peresented the new Big Pilot’s Watch Perpetual Calendar Edition Racing Green IW503005 in ceratanium with a price of €32,100.

IWC has just introduced the Big Pilot’s Watch Perpetual Calendar Edition Racing Green, a 250-piece limited edition combining a black zirconium oxide ceramic case to a dial in a striking racing green.

The zirconium oxide ceramic is a high-tech material that IWC pioneered in the 1980s. It uses an engineering ceramic that is one of the hardest substances on earth. Polycrystalline powders are mixed with auxiliary substances to form a homogenous mass, shaped and then sintered at high temperatures in a kiln.

46 mm in diameter and 15.6 mm thick, the case is completed by a conical crown and a case back ring made of Ceratanium, another special alloy developed by IWC that is light as titanium and hard and scratch-resistant as ceramic.

 

The green dial displays date and power reserve at 3 o'clock, month at 6 o'clock, day of the week and running seconds at 9 o'clock.

At 12 o'clock, the moon phase display shows the moon as seen from the northern and southern hemispheres. Thanks to its accuracy, it it will only need to be adjusted by one day after 577.7 years. 

The renowned perpetual calendar developed in the 1980s by Kurt Klaus, then head-watchmaker at IWC, also integrates the signature four-digit year display that can continue to function until 2499. 

The gold-plated hands and the golden moons add a warm touch to the refined sun-brushed dial.

The calendar module is comprised of about 80 individual parts and driven via a single nightly switching impulse by the IWC-manufactured 52615 calibre. 

This 4 Hz (28,800 vibrations per hour) automatic movement builds up a power reserve of seven days thanks to its Pellaton winding system and two barrels. The components exposed to high stresses and strains are made of non-wearing ceramic.

The finishes of the movement and its rotor with an 18-carat gold medallion can be appreciated through the sapphire glass back.

Water resistant to 6 bar (around 60 metres / 200 feet), the IWC Big Pilot’s Watch Perpetual Calendar Edition Racing Green IW503005 is matched to a black calfskin strap with a pin buckle and has a price of Euro 32,100. iwc.com
