Up for sale is my Seamaster 2846, Cal, 501. Great stainless case with lugs in great condition, still showing chamfers. I am by no means an expert on these, but the large hippocampus case back seems less common than the flat case back based based a google search. The crown has been replaced, but the clover replacement is readily available. Dial is in really nice shape with gold hardware, hands show some oxidation. The crystal has light scratches and the watch could benefit from a new one. The watch keeps reasonable time, but has not been serviced in my possession. Sold head only, with no accessories included. Asking $725 USD net to me (paypal, wire, Chase Quickpay) including 2-day FedEx in the US. International shipment to be discussed. Please let me know if you have any questions, and as always, thank you OF for the space and outstanding community!
