Vintage Timex Divers  Wristwatch.  I assume this is from the 1970s.  This watch measures 36mm across, or is 39mm across including the crown. The dial reads "Timex Water Resistant 25 Metres 2767202574". There is a calendar at  3 o' clock. The bezel rotates. The watch does not have a screw down crown. The caseback reads "Water Resistant to a Depth of 25 Metres".  The inside caseback reads "Case France Timex". The movement reads "Great Britain". The watch winds, sets and works properly. The date turns over correctly. The movement moves slightly in the case, when winding or setting. It is a vintage divers style watch, with a fairly basic movement, so don't expect it to run like a Casio timewise. It is not suitable for swimming, diving etc.
