Manufactured by Certina, the DS-3 was selected for service by the Royal Australian Navy (RAN). The back of
the case has the NSN (National Stock Number) and issue numbers engraved indicating it's use by the RAN.
Originally issued in the early 70's, only a very few of these issued watches have appeared in the collectors
marketplace making it one of the most sought after military issue watches.
The designation DS stands for "double-security", referring to the water resistance of the case and the
rubber-mounted shock protection of the movement. The DS-3 has a water resistance rating of 1000 meters.
