Bulova 1971 Deep Sea Chronograph parts needed
I am in the processes of repairing / restoring a Bulova Deep Sea Chronograph (link from this sight http://www.mybulova.com/watches/1971-deep-sea-chronograph-1769) for a customer and am looking to source some parts. Main things needed are a crystal, bezel, and rear gasket. I might need a mainspring depending on how well this thing runs after a good cleaning, and the bezel spring if the new bezel does not come with one.
Serial numnber is "3 255277"
Year marker is "N1"
Here are some pictures of the watch. The resolution came out a bit rough, so I typed in some of the details. If anyone has parts, or knows the best place to get parts that would be helpful. My usual search places could only offer a crystal without the bezel ring lip, and no one had bezels. Thanks again for any info.
