The Miyota caliber 8205 is a 21 jewel automatic movement introduced to the watch market in approximately 1977. Featuring a ball-bearing rotor, this Japanese-made movement is commonly found in microbrand watches due to its availability and affordability. Considered an entry level workhorse movement, it offers a range of functions including sweep seconds, a day/date calendar at either 3:00 or 6:00 position with quickset options, and central hours, minutes, and seconds hands.
