Understanding the 21 Jewels Movement
One of the main reasons I was drawn to this watch is because of its 21 jewels automatic movement.

I kept track of the watch’s timekeeping over several weeks, and it maintained accuracy within a reasonable range for an automatic watch. It gains or loses only a few seconds per day, which I find acceptable without needing constant adjustment.
