Reverso One Cordonnet

In Context

At 16.3 mm this is jewellery scale — a watch sized to be worn as an ornament rather than read across a room. The 7 mm case is genuinely slim and goes under a shirt cuff without argument. The case back is closed, so the movement stays out of sight. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

It is quartz, so it will hold time far more closely than any mechanical watch here, and asks for a battery every few years rather than a service.

3264520 stands on its own in this catalogue — no other reference here shares its base number. It pairs a white guilloche dial with a rose gold, stainless steel case.

The 657 is Jaeger-LeCoultre's small quartz movement with hours and minutes only, for the ladies' Reverso. It powers 31 watches in this library, every one a Reverso. It oscillates at 32,768 Hz with 4 jewels, and its two-hand display suits a rectangular dial without a seconds hand ticking across it. It is the movement of the Reverso One and of the Grande Reverso Lady Ultra Thin quartz models, which put the swivelling case on the wrist without winding or a rotor. In the library it powers 31 [Reverso](/brands/jaeger-lecoultre/reverso) references, with case widths from 16.3 mm to 24.4 mm, in steel and pink gold, many with diamonds. The [846/1](/calibers/jaeger-lecoultre-846-1) is the hand-wound movement of the same ladies' models, and the [822](/calibers/jaeger-lecoultre-822) the hand-wound caliber of the men's Reverso.

30 other watches in the library run the Jaeger-LeCoultre 657.
