It's Complicated!
From watches that simply tell the time,
to ones that tell the date or a chronograph which allows one to record time
intervals, much like a stopwatch, we
move onto the serious business end of
watches-the COMPLICATIONS.
Basically these watches are called so
because they really are very complicated.
The various complications available are
the tourbillon, minute repeater, perpetual
calendar, worldtime and a few others.
In this issue I'll concentrate on my
personal favourite and, in my opinion,
the most 'romantic' of all the complications: the perpetual calendar. These sorts
of watches are serious 'legacy' pieces and
qualify for heirloom status.
The perpetual calendar will display the
day, date, month and either leap year or
full year along with phases of the moon,
and will be able to adjust for the varying
days in each month, including leap years
all the way up to the year 2100.
Why up to 2100? We follow the Gregorian calendar, which has a leap year every
four years. In the year 2100 this is broken,
so a perpetual calendar watch needs to be
sent for a small correction in that year.

Note in the photo at bottom left the
full calendar display, including the year in
four digits! A sort of time machine on the
wrist. Make your New Year's Eve celebrations even more exciting by watching the
year to change on the display.
In the photo below we can clearly see
the date display. A tremendous amount of
energy is required on Feb. 28 to switch it
all the way to March 1.

Royal Oak perpetual calendar
in steel and platinum from 1997

Note the month hand and smaller hand
to show the leap year on the Audemars
Piguet Royal Oak Perpetual.
So there you have it, ladies and gentlemen-the daddy of all complications. It
would make a perfect heirloom watch,
especially one with the full year shown.
Just imagine a family member in the year

2100 taking it in to the watchmaker for
an adjustment-would make for one heck
of a story!
Keep a look out for my future articles
where I will be discussing the real iconic
watches to collect, interviewing the owners of a high-end watch boutique, and
video reviews of the latest timepieces! ■
