PORTUGIESER CONSTANT-FORCE
TOURBILLON EDITION “150 YEAR S”
REF. IW590202
There are several firsts built in to this highly technical piece, offered in a
limited edition of fifteen platinum-cased pieces. Primarily, it is IWC’s first
to combine a long power reserve (96 hours) with a constant-force
tourbillon and a perpetual moon phase display. The moonphase here is
also unusual in that it needs to be adjusted by one day after 577.5
years. As with many of the other of the new Jubilee editions, the watch
has a white dial with a lacquered finish and blued hands. The move-
ment responsible for the technical superlatives is a new one, Caliber
94805, a manual-wind model with a patented constant-force mecha-
nism that transmits completely even impulses to the escape wheel.
PORTUGIESER PERPETUAL CALENDAR
TOURBILLON EDITION “150 YEARS”
REF. IW504501
This new piece combines a perpetual calendar with a tourbillon on the
dial, a first for IWC. This 45mm red gold watch also offers a white dial
with a lacquered finish and blued hands, and is also limited in number
(fifty will be made). New IWC Caliber 51950 is an extension of the basic
IWC 51900, but here includes a perpetual calendar. The tourbillon is
visible at 12 o’clock because the watch designers opened the calendar
advance ring t o integrate the moon phase at 6 o’clock in the month
display disc. With its solid gold rotor, the automatic winding system
generates a power reserve of seven days.
THE DA VINCI AUTOMATIC MOON
PHASE 36 EDITION “150 YEARS”
REF. IW459304
With this elegant jeweled model, IWC picks up where it left off in earlier
decades when it created a broader collection of diamond-set watches.
The Da Vinci Automatic Moon Phase 36 Edition 150 Years is cased in red
gold and offers a white dial with a lacquered finish and blued hands. It is
available in a limited edition of 50 watches. The watch’s moon phase
display at 12 o’clock competes for your attention with a case and
moving lugs that are completely covered by 206 (2.26 carats) of
white diamonds.
THE DA VINCI AUTOMATIC
EDITION “150 YEARS”
REF. IW358102
Another early 2018 favorite of mine, this simple dress watch with its
small seconds at 6 o’clock is the first watch to feature the new IWC-
manufactured 82200 Caliber. The watch has a stainless-steel case, a
blue dial with a lacquered finish, and rhodium-plated hands. It is avail-
able in a limited edition of 500 watches. The newly developed caliber is
an automatic movement with Pellaton winding and boasts a power
reserve of sixty hours. Components in the system subject to
pronounced stress, such as the pawls or the heart-shaped cam, are
made of virtually wear-free ceramic—a technique which IWC will likely
continue as it expands its caliber-development capabilities at its new
manufacturing facility in 2018. iW will have more on all the 2018 IWC
debuts in January on iwmagazine.com.
