Recent $10 purchase. 1975 ref 1660 163. Cal 1010 17 jewel. So entry level Omega. 20 micron plating that shows noticeable wear. 14k gold filled beads of rice band that is in quite decent condition. (Has # 70 on end links but no number on bracelet). Crystal clean but not signed. Crown is signed. Movement looks clean. Dial is perfect. I Would consider replating this piece. However not running. I can get the balance to run for a few seconds and then stops. But the second hand does not move at all when balance is running. Any idea what this means or how big a fix? At low initial cost I have financial wiggle room. Be helpful to know something about this before a consult with watchmaker.
