Common questions about the Patek Philippe Complications 5905/1A-001

How big is the Patek Philippe Complications 5905/1A-001?

The case measures 42mm across. Case material: Steel. Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

What movement is in the 5905/1A-001?

Automatic, Caliber CH 28-520 QA 24H. Power reserve is 45 hours. It beats at 28,800 vph.

Is the 5905/1A-001 water resistant?

It is rated to 30 meters, about 98 feet. That covers rain and hand washing. It is not rated for swimming. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

Does the 5905/1A-001 have a nickname?

Annual Calendar Chronograph. Collector nicknames are not official Patek Philippe names, but they are what people actually search for and what they are called across a showroom.
