Part of the Miyota Cal. 8200 family, Cal. 82S7 (and the similar Cal. 82D7) is an open heart movement with small seconds and a 24 hour subdial. Cal. 82S7 and 82D7 remain in production as of 2019. Gilt versions are also available. The primary difference between 82S7 and 82D7 is that the latter is better finished, with ribbing on the plates.
Cal. 82S7 is used by Dietrich and SevenFriday.
