If a watch earns its nickname because of its distinct features, I am sure it is a special watch that worth all watch collector's attention. Selected as one of the most common watches for servicemen back in Vietname war, the Seiko 6309-7040/9 is a perfect definition of a tool watch. It's as rugged and hard wearing as it is aesthetically satisfying. Even as the first "Turtles" was released from 44 years ago in 1976, one thing is certain... they don't get old.

We have sourced a very special example giving the perfect sign of vintage feeling from the watch. This example from Jan of 1985 was one that we just couldn’t pass on. The dial is the third variance of 6309 with red water resist text aged to greenish grey and a small Suwa logo together with the watch model  '6309 704MT' at the bottom of the dial. The third variance is known to be more rare compare with other dial variances. 

The matte black dial is in great condition overall with perfectly developed patina throughout the hour plots. The hour and minute hands is original and developed a matching lume with the dial. The mineral crystal is scratch-free. The bezel has aged into a dark grey (same as the vintage Submariners) and rotates with click in either direction. The day and date can be quickset via the crown. The case is in mint condition with minor usage mark and the original finishes still visible.

We suggest you pair this vintage piece with our Nato strap or our Premium Rubber straps which makes it a perfect all-occasion watch for your day. You will only find it getting rarer for a vintage diver with such an amazing condition, get it before its gone.
