Michael Friedberg Wrote:Hi Hebe,This watch has a "snail regulator", which is uncommon but found on some calibres of this era. Ralph Ehrismann estimated that between 2000 and 5000 IWC movements in the early 20th century had this cam system. This was discussed in 2001 on the forum, and an archives search should help.
