Picked up an Omega automatic Geneve -steel case with surprisingly original leather strap. With minimal servicing gives very accurate time. Gilded Swiss made Automatic Movement, Fine Regulation, Stainless Steel Case with Screw Back Marked "Wateproof", Case Diameter 34mm (not Counting Crown), ca. 1970
I wear it everyday- i bought it in virtual broken condition and restored it over a period of six months. Cost $ 700 (including restoration). procuring parts was the difficult task and i had to hunt in junkyards, pawn shops etc to get pieces.
