In Context

At 38.6 mm it sits just under the modern norm — the band that suits the widest spread of wrists. 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 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.

5089G-145 is one of 45 executions of the 5089G base reference. Underneath they are the same watch; what separates this one is a multi-color gloss dial and a white gold case. It was a limited edition.

Patek's ultra-thin automatic, introduced in 1977 as a mechanical answer to quartz on the one ground quartz had won: thinness. A 22K gold micro-rotor recessed into the mainplate rather than sitting above it holds the movement to 2.53 mm across a 27.5 mm diameter. The 3 Hz balance is deliberate — a slower beat draws roughly a fifth less energy than 4 Hz, which is how a rotor that small still keeps the mainspring wound. It runs a Gyromax balance, and underpins the thinner Calatrava, Nautilus and Aquanaut references.

149 other watches in the library run the Patek Philippe 240.
