Hi Henry,
In fact I didn’t know the existence of this watch before I walked into the JLC boutique at 1881 Heritage. You are based in HK right? May be you can drop by to have a look at it personally (If it’s still there).
Things I can confirm are that on the case back it said: “Limited Series of 8 pieces”. It also has a case code of “273.3.62” which is exactly the same case code of the blue enamel version (limited to 50 pieces). That means both the blue and red enamel reversos share the same white gold Grand Reverso case, and the same movement. (Please correct me if I’m wrong).
I’m afraid I didn’t get the Catalog number or when this red enamel reverso was made and for what occasion. If anyone know anything about this watch, please shed some light. I would also like to know as well.
Best,
David
