In Context
At 52 mm this is exceptionally large for something worn on a wrist, closer to a pocket watch given lugs. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.
The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 55 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 18,000 vph the seconds hand advances 5 times a second, the slower and more audible rate of an older design.
PAM00300 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case. It was a limited edition.
