The Miyota 8210 watch movement, used during the period from 1962 to 1965, features a ball-bearing micro rotor and a detached manual wind mechanism. It is equipped with a micrometer regulator and a Girocap combined settings for the escapement wheel if 28 jewels are present. The indirectly driven minute and second hands allow for a low profile. Furthermore, this movement resembles the 218-2 model but entails an improved winding mechanism. Additionally, the Miyota 8210 movement incorporates automatic winding, a sweep second hand, and a date function that can be adjusted by changing the 21-24h.
