First, one of the three cover lots to the catalog is a Patek
Philippe reference 3448.  The 3448 was
PP’s first self-winding perpetual calendar, and it is, in my opinion, one of
the coolest and most user-friendly mega vintage Pateks.  Obviously, I adore the old manually wound
chronographs, the manually wound perpetual calendars, and certainly the manually
wound perpetual chronographs like the important 1518 and the downright perfect
2499,
but day in and day out, do you want to wear a perpetual calendar that
doesn’t keep itself going?  I do, but
then again I’m more into frivolous horological purity than most, and since I
haven’t had the opportunity to wear a 1518, 2499, 3970, 5970, or 5270 for any
great length of time, it is entirely possible that the novelty of the manually
wound perpetual might wear quickly – I will say that though this Universal
Geneve Tri-Compax I bought at Sotheby’s last year
is absolutely one of my
favorite and most prized watches, the thing is a royal PITA to set after not
wearing it for a while.   So, if you want
a vintage complication, you’re left with nothing but the 3448.  The 3448, like most big watches of the
day, was produced mostly in yellow gold.  But the watch we’ve got here is indeed a
vintage self-winding perpetual calendar from Patek Philippe, and it happens to
be in white gold. 

The thing is absolutely beautiful. And, the combination of the funky little leap-year indicator at four
o’clock and the white gold makes this an extremely rare watch. You can all but
guarantee that you could wear this perpetual calendar every day and few people, if any, would suspect you’re wearing $1 million on the wrist.  The watch is awesome not only for the
complication or the rarity, but mostly because of the wearability.  Christie’s has a pre-sale estimate of $860,000 to $1.5m and more details can be seen here.
