Up for sale is my Unimatic U3-F. This Italian made 300 meter diver features a screw down crown and pushers and is fitted with Seiko's VK64 meca-quartz chronograph movement. This particular example is number 83 of 600 produced.
The dial features silver print, maxi-style indices and black painted hands with a white tipped chrono seconds hand. Hands, indices and the lollipop on the tail of the chrono seconds hand are painted with C1 lume. The fully indexed, 120-click bezel has a lume pip at 12 and an aluminum insert.
The Seiko VK64 movement employs quartz time keeping but is fitted with a mechanical chronograph gear train, meaning elapsed time functions behave like a mechanical chronograph, complete positive clicks from the pushers, a chrono second hand that ticks 5 times per second and snap-back reset. The 9 o'clock subdial tracks elapsed time over 1 hour. The 3 o'clock subdial tracks 24-hour time and is slaved to the minute and hour hands.
The case is fully brushed stainless steel with a screw-down caseback and UNIMATIC branding between the 12 o'lock lugs. This is a no-date watch.40mm case diameter41.5 mm bezel diameter51mm lug-to-lug22mm lug width14mm thickness, including the 2.5mm thick sapphire crystal with internal AR coating120 click fully indexed unidirection diving bezel with lume pip300m water resistanceSilver dial printing with black hands, white tipped seconds hand and C1 lumeScrew down crown and pushersSeiko VK64 movement features mechanical chronograph functions, quartz timekeeping and stated accuracy of +/- 20 seconds per month
