The Zodiac Sea Wolf was one of the more popular watches with servicemen during the Vietnam war. Originally launched in 1953, the Datographic version of the watch was launched in 1962; smaller and slimmer than other contemporary dive watches, it nevertheless claimed a 200 meter depth rating similar to the 5512 Submariner, despite the fact that the Zodiac had a snap back, not a screwed one.
The dial is high gloss black with large luminous triangles at the quarter hour marks with the Arabic hour numbers below the luminous, there is a date window at 3 surrounded by a silvered metal frame. There are applied hour baton indices, each with a stripe of luminous in their centre and an outer silver print minute track. The centre off the dial is very busy, with a Zodiac ‘sniperscope’ logo under the 12 and the brand name just underneath and beneath that the model name. Just above the 6 is the word ‘Automatic’ and at the very bottom of the dial is ‘Swiss T 25MC’. The triangular hands have large tritium inserts held in place by a ‘backbone’ running down the centre of each hand.
The case is of unusual construction, in that it has a snap back, which is very rare in a 200m rated dive watch but which certainly contributes to the slimness of the piece. The bidirectional ratcheted bezel is also unusual in that the Bakelite insert is a very light blue colour, with a large tritium triangle at 60, minute markers between it and 15 and just the single number 30 at the very bottom of the bezel insert. The actual bezel is of a similar material to contemporary Rolex ones, a rhodium finish over a brass metal, and like most Rolex ones, the rhodium has disappeared leaving a brassy appearance.
The movement is the Zodiac signed 722-916, based on a A. Schild manual movement with the addition of an automatic winding module, it beats at the unusual rate of 21,600 and has 17 jewels and is unadjusted. It has Incabloc shock protection and is stamped with the import code KXF near the balance, which was the US import code for Zenith.
The case is 90%, whilst the movement & dial are both 95%.
