I owned the JD Les Lunes in 40mm with a white and grey dial combo. JD makes poetic timepieces for me but, sometimes, they’re too big (43mm) in my opinion for such dressy watches.
If I should buy one again today, I think I would go for the “Date Astrale” black dial in 39mm.
Your JD is a “numerus clausus” or not?
