I have 6 Seiko autos. 7S26, 7S36, 4R36 all of em ran at least 15 to 20 secs
fast until they were "worn in".
4R36 the most accurate of the herd. 4 to 6 sec + each 24 hours.

Have a new Vostok Kommanderiske, 17 jeweled, 2414 engine. Avg 4 to 6
secs + each day. Really hard to assess accuracy since none but the 4R36 will
