One still exists, the 5140, with the enamel dial...
The other one I know was the 1775, released under subscription for the 225th Anniversary ( curious, another Jubilée piece which comes with an enamel dial...), and which was Limited to 225 pieces...
Platinum, 35 mm, 2 Case Back, one with a sapphire, the other which was platinum solid...
I owned this one, and If I sold it, it was because I missed the platinum solid case back...
So, I regreted it, and was looking for another enamel dial...
This Lange is, for me, one of the nicest, if not THE nicest I know...
Exquisite is the word which corresponds the most for this Masterpiece!
Best, my friend!
