Citizen 8210

Miyota's workhorse automatic caliber widely used in Citizen-branded watches and as a third-party supply movement. Running at 21,600 vph with 21 jewels, it offers reliable timekeeping with both hacking and hand-winding. The 8210 is essentially the same platform as the 8215 but with the addition of hacking capability, making it a more refined option for mid-range watches.
