A vintage c1956, textured white gold cased Omega 17 jewel, grade 302 mechanical hand wind movement(serial #15869436) wristwatch. Presently runs and keeps good time. I do not know when the watch was last serviced.  The case measures 33mm long(tip of lug to tip of lug) x 28mm wide not counting the crown. The bezel shows a textured finish. The crystal is clean and clear with no chips or cracks but does show some small, light surface scratches. The dial is relatively clean. It is not marked Swiss and does not appear to have been repainted. The black leather bracelet is a new replacement. Please enlarge all pics for best details.
