Case measures 34.08 mm.  Distance end of lug to end of lug is 39.63 mm.  Distance between the lugs is 17.25 mm.  The watch is not running.  Movement marked Omega Watch Co Swiss Seventeen 17 Jewels Unadjusted.  I also see the omega symbol with 470 under it, and the letters AZZR and OXG.  The serial number is 16800972, which I believe indicates 1958.  There is a scratch on the acrylic crystal, and fine scratches on the crystal when viewed with a 10x loupe.  There is also a scratch on the back cover plate.  Marked 10k GF Bez Steel Back. The band is not an Omega band.  One of the pins that holds the band on is missing.  Watches are not my forte, so please ask me questions if you need more information.
