I have recently been given this watch. I cant find anything about it on the net and my local jewellers are unable to help. I can read the following numbers 16599470 and AZZR on the watch and PW2630 in the tiniest writing I have ever seen on the watch back which also has JK156 OEMGA WATCH CO O.T.2267 Steel Thread 18K 0750 Any help would be greatly appreciated!!
