I thought I might contribute some scans of the Grande Reverso Sun Moon (in SS), since there do not seem to be many on the web. Perhaps this will interest JLC enthusiasts as well as potential buyers.
Without doubt, the Reverso Sun Moon is a very elegant watch, and the movement is beautifully decorated. A sunburst pattern and a constellation of rubies and blued-steel screws on the movement carry the celestial theme to the reverse side of the watch. (An interesting detail: the constellation is supposed to mimic one that passes over the manufacture Jaeger LeCoultre in the Valée de Joux.)
Please forgive the fingerprints. These pictures were taken quickly and without a macro lens. So, Without further ado, here are some images.
