Omega described this watch as, from the International Collection. This model is a gent’s wristwatch in stainless steel.

The watch is in excellent condition showing only small signs of wear. Sturdy barrel-shaped,one piece, "Unishell" type case that opens on the dial side i.e. you need to take the glass out and there is a tool for doing this that most good watch makers will have. The official version supplied by Omega being given reference "Tool 107" hence this forms part of the watch model reference number.

This watch still has its original Omega signed crown and armoured hesalite crystal also signed in the centre. Both in excellent condition.

The case measures 35 mm not including the crown and 37.5 mm with! Again the case is in excellent condition showing very few and then only tiny signs of wear!

Embossed on the back with the Seamaster, Seahorse and Omega logo, with "waterproof" and watch model ref. "166026-TOOL 107".

Factory-original two tone silver and grey outer chapter ring dial in excellent condition with no signs of age! Silver stick hands, applied hour markers, steel central seconds and day-date aperture at 3. The face is also signed Omega, Automatic, Seamaster Cosmic, T-Swiss Made-T.

Authentic Omega automatic Caliber 565 with 24 Jewels. Keeping excellent time. Quick set date by pulling out the crown all the way and quickly pushing back in!

Overall this has to be one of the nicest examples of this model we have seen and to enhance it we have found what we were told is a NOS blue Omega vinyl band with a period Omega signed pin buckle which we have put on the watch as you can see from the photo's. The band looks great and the blue really picks out the dial and hour markers very nicely. We cannot however be absolutely sure that the band is genuine so will just call it "after market" and let you decide for yourself. Please don't however think that the band detracts from the watch as we can assure you it does not!

A fantastic watch for any collector!
