Pictured here on a nylon NATO strap, this watch has a "military" style that reminds me of the RAF and RN issued Seiko quartz chronos
of the '80s -'90s. This new watch operates as follows: The sub-dial at 12 records time in intervals of .05 seconds, stopping at 10
minutes to conserve battery energy. Although the hand has stopped, the movement is still running in the .05 sec mode and the hand will
move to the timed position when the chrono is stopped. The sub-dial at 6 has two hands and records hours and minutes up to 12 hours.
The sub-dial at 9 is continuous running seconds.
Compared to the vintage RAF/RN issued watches, the SNDA67 has a larger case and dial, allowing larger, easier to read subdials. I
also like the 22mm lugs and fantastic lume. This watch glows as well as Seiko's dive watches which are well known for bright,
long-lasting lume. While the vintage RAF/RN issued chronos rarely appear in the collector marketplace, I did recently see a clean
example of a gen 1 RAF watch sell for $750. Current internet pricing on the SNDA67 is approx $125-135.
