Reverso One Jewellery White Gold / MOP / Satin

In Context

At 18 mm this is jewellery scale — a watch sized to be worn as an ornament rather than read across a room. 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. Its 38-hour reserve wants wearing most days; leave it off and it stops. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

3363401 stands on its own in this catalogue — no other reference here shares its base number. It pairs a white dial with a white gold case. Introduced in 2017.

The 844 is the hand-wound movement of the Reverso Duetto: one caliber driving two dials, so the swivelling case shows a different face on each side. It powers 23 watches in this library, every one a Reverso. Where a Duoface shows a second time zone on its reverse, the Duetto shows the same time twice, on a day dial and a jewelled night dial, from one set of gears; the 844 has hands on both faces. It beats at 21,600 vph with 18 jewels and a 38-hour reserve, in the small rectangular size of the ladies' Reverso. In the library it powers 23 [Reverso](/brands/jaeger-lecoultre/reverso) references, the Reverso Classic Small Duetto and the Reverso One Duetto and Jewellery models, with case widths from 18 mm to 21 mm, in steel and pink gold with diamonds. The [854A/2](/calibers/jaeger-lecoultre-854a-2) is the two-dial movement of the men's Duoface, with a second time zone, and the [846/1](/calibers/jaeger-lecoultre-846-1) the single-dial hand-wound movement of the ladies' Reverso.

22 other watches in the library run the Jaeger-LeCoultre 844.
