The Big Pilot 's Watch Perpetual Calendar TOP GUN Edition "Mojave Desert"
(Ref. IW503004) presents IWC's legendary perpetual calendar in a sand-coloured
ceramic case for the first time. The ingenious mechanical program, which
automatically recognises different month lengths and leap years, was developed
in the early 1980s by IWC's former head watchmaker Kurt Klaus. The moon phase
display correctly depicts the moon phase for the northern and southern
hemispheres and only needs to be adjusted by one day after 577.5 years.
Because its displays are perfectly synchronised, the calendar can be advanced
easily via a single crown. The calendar module, which is constructed from 82
individual parts and features a four-digit year display, is powered by the
IWC-manufactured 52615 calibre. The automatic Pellaton winding system,
reinforced with virtually wearfree ceramic components, builds up a power
reserve of seven days in two barrels. The movement, including key elements
like the rotor and the balance wheel, is visible through the sapphire crystal
case back. Production of the watch will be limited to just 150 pieces per
year.
The Big Pilot 's Watch TOP GUN Edition "Mojave Desert" (Ref. IW506003) is
the first Big Pilot's Watch to be made in sand-coloured ceramic. Inside the
46-millimetre case, the IWC-manufactured 52110 calibre with Pellaton winding,
two barrels and a seven-day power reserve is at work. A soft-iron inner cage
effectively shields the movement from the effects of magnetic fields. The
legendary TOP GUN logo is engraved on the titanium case back. This model will
be limited to just 250 pieces per year.
