844

About the Jaeger-LeCoultre 844

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 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 is the two-dial movement of the men's Duoface, with a second time zone, and the 846/1 the single-dial hand-wound movement of the ladies' Reverso.
