Chanel dropped some new “anniversary” ceramic at Baselworld 2010 with the help of the team at Audemars Piguet Renaud Papi. Looking at the photos really does not do justice to what the mechanics of the watch are doing. You may need to read this twice to grasp the complication.
“The name of this watch is beginning to take on meaning: Rétrograde for the minute hand which reverses its travel for ten minutes during which, at each revolution of the dial, the hand returns to its position under the crown -i.e. between 10 and 20 past each hour, with the minute counted in figures in the magnifying aperture at the bottom of the dial -and Mystérieuse for the mysterious workings of this dual analog and digital display. It is a highly technical and very aesthetically-pleasing watch complication.” One final note on the crown: it’s verticable retractable. The photo above shows its position. (timezone)
