Yes, you are so right! Really sorry it ended this way for you my issue was also around keeping the watch looking aged and original.
Well, have had a response from Omega and although still insisting that there had been no intervention (even though clearly the stem and glass must have been replaced) they are going to investigate. Still no response form the CEO, well not surprised really!
I am still thinking of a new Omega SM 300 purchase even after all this. Am I crazy? Will keep you guys updated with developments!
