Up for sale is my Serica 5303-1 black dial dive watch in excellent condition. This is the non-COSC version, but on my wrist, it seems to run about +2 secs a day. Haven’t had any issues with the crown or movement. No scratches that I can see on the case, bezel, or crystal. Only a few scratches on the lugs from strap changes. Bracelet is incredibly comfortable!
