I have three omega Clover crowns for sale. These are for the Seamaster 1950's watches. The two on the top row appear to have the older logo which would indicate they are original to the 1950's. One has oxidized and the other is in good shape. $25 for each + shipping. Bottom one appears to be a newer replacement crown. $20 plus shipping. PayPal or Zelle. Crowns located in USA. Feel free to reach out for any questions. Thank you! Ben
