IWC Museum (thank you David Seyffer) shared some of the treasures with Moscow
boutique for 3 weeks.
2 days ago it was presented to media, but it's opened for public in working
hours.
Some amazing pieces came like Jones caliber from 1875, pattern R and Pallweber
III from 1885.
Portugieser ref. 325 from 1942 and Portugieser Automatic from 2001.
Ingenieur and Romana perpetual calendar ref. 2050 from 1995. (for Inge it was
indicated that it's 666A from 1955, but I'm afraid it's more close to end of
60-beg. of 70).
I think my Inge is more close to first ones:
Da Vinci in ceramic case ref. 3755 from 1986
Ref. 2400 from 1974, Pilots UTC in platinum ref. 3251 from 1998 and Aquatimer
ref. 812 AD
