Pocket Watch Lepine Power Reserve White Gold / Geisha under a Cherry Tree

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. The sapphire crystal will resist everything short of deliberate abuse.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. Its 36-hour reserve wants wearing most days; leave it off and it stops. At 18,000 vph the seconds hand advances 5 times a second, the slower and more audible rate of an older design.

982/140G stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue guilloche dial with a white gold case. It was a limited edition.

The 17''' LEP PS IRM is Patek Philippe's Lépine pocket-watch movement with a power reserve indicator. It has 158 parts, 20 jewels and a 36-hour reserve in a 17-ligne caliber of 38.65 mm. It powers 16 watches in this library, every one a pocket watch. A Lépine movement sets the small seconds at 6 o'clock opposite the crown at 12, and this one adds a reserve hand to the dial; it beats at 18,000 vph and is 3.8 mm high, finished under seven bridges to the Patek Philippe Seal. The glossary defines the [power reserve](/glossary/power-reserve) it displays. In the library it powers 16 [pocket watches](/brands/patek-philippe/pocket-watches): the ref 972 Lépine Power Reserve in yellow and white gold, and the 982 references from the Rare Handcrafts workshops, with enamelled and engraved cases; 15 of the 16 are limited editions, and 12 are in the 44.1 mm case. The [17''' LEP PS](/calibers/patek-philippe-17-lep-ps) is the same movement without the indicator, and the [17''' SAV PS](/calibers/patek-philippe-17-sav-ps) the hunter-cased Savonette version.

15 other watches in the library run the Patek Philippe 17''' LEP PS IRM.
