The cal. 921 has 21-jewels and was produced in larger numbers than the cal. 923, which has 23-jewels and a slightly higher level of decoration. It’s estimated less than 4000 of the cal. 923 were made.
The somewhat generically shaped steel case is 41mm with a screw-down back and onion-shaped crown.
Price and availability
The Model 222-RR with a cal. 921 is priced at US$5900, while the same with a cal. 923 costs US$7900.
