Hello all, and thank you for allowing me to be part of this amazing Bulova resource. I sell vintage watch parts & materials on eBay. I recently acquired a large Bulova parts collection from a retired watchmaker and have been listing away for the last two weeks. Yesterday, I realized some of my sealed old stock parts are degraded and rusted, making them worthless. Now I am in a rush to go through the 100s of parts I've listed and check each for condition. I advise those buying New Old Stock parts online to ask the seller to open the part and check for condition before you waste your time and money purchasing.
