The Seiko caliber 6810 is an ultra thin mechanical watch movement found in Seiko U.T.D. (Ultra Thin Dress) watches.
Before the 6810, a similar UTD movement known as the Seiko cal. 68A was produced at Morioka Seiko Instruments from 1969 until the 6810 was introduced in circa 1972~1972.
The 6810 was also used in the limited edition “110th Anniversary” UTD watch launched in 1991 (only 110 pieces were available worldwide).
