These used to be around but ready supplies seem to have disappeared. People justifiably hoard Enicar parts, especially cosmetic parts, as they have been out of production for over 40 years.
What I do now is buy watches for their parts. You could buy another 36mm Diver/Divette/etc, remove its red pointer and then sell it on at a bit of a loss.
Hi @MatthewT , sorry for the late reply.
the inner diameter should be around 29 mm, i don't know how exactely misure it. Many thanks in advance.
Have a nice day
