I'm new to the site and have a couple of questions I hope someone can help me with. Twenty years ago, I traded for a 1968 Oceanographer Snorkel, 666 ft, Swiss Automatic. Wore it for 15 years and loved it. Five years ago, it fogged up after minor contact with water (caught in the rain). I brought it to a local watchmaker who cleaned, oiled, and adjusted it. He said it was in excellent condition. I had wanted him to replace the crown (for waterproofing) and crystal (for appearance). He later advised he could not find parts and recommended I just hold on to it and not wear it (which is what I've done, periodically winding it to move the oil). A year ago, I inquired of several watch restoration services that I found on the web and was led to believe that waterproofing was probably not possible. I sent it to the Bulova service center in New York, which promptly returned it saying parts were not available. Do I have to just accept that waterproofing is unachievable (I don't dive and am only hoping for protection from incidental water contact)? If not, who could do such work? Also, can a replacement crystal (mineral or sapphire) be found? I really miss the watch and would love to wear it again. Thanks.
