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: 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'clock lugs. This is a no-date watch.
*Condition notes: This is a used watch. Photos reflect condition, which is excellent overall. There are few barely noticeable nicks in the brushed finish.
$525 includes USPS Priority Mail shipping. Paypal or Zelle. USA buyers only. Not interested in trades at this time.
