Hi Back again. I inquired about having a lug welded back onto a late 60's Omega Seamaster Deville awhile back. Well I ran across a NOS replacement case and bid on it but I'm not so sure I did the right thing. The case looks right but the reference number is not the same. The number for the case is ref No. LL6066. My watch is apparently a 165.020 A Deville face that looks identical to mine comes with it but the seller says he does not know if the face is right for the case. I'm only interested in putting the watch back into serviceable shape, not whether numbers match so long as there's dimensional interchangeability of cases.
