Part of the Miyota Cal. 8200 family, Cal. 8N24 is a skeletonized three-handed movement. Cal. 8N24 remains in production as of 2019. A gilt version is also available. Cal. 8N26 is similar but with a longer hand mounting pinion.
All members of the Miyota 8200 family have indirect seconds, which causes a noticeable wobble to the central seconds hand. When struck, the seconds hand can appear to pause for up to 2 seconds due to slack in the movement.
