Calatrava Cortina Watch 50th Anniversary

In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. 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. 60 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement winds itself from the motion of your wrist. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

5057G-010 stands on its own in this catalogue — no other reference here shares its base number. It pairs a grey dial with a white gold case. It was a limited edition.

The calibre 240 with a power-reserve indicator (IRM), date hand (C), moon phase (LU) and small seconds (PS) built onto it. The base's off-centre 22-carat gold micro-rotor sits within the movement rather than above it, so carrying four extra displays still leaves the calibre under four millimetres thick. The rotor winds in one direction only, and the balance is a free-sprung Gyromax.

10 other watches in the library run the Patek Philippe 240 PS IRM C LU.
