I purchased this Bulova on ebay. It is in great shape, and has been running perfectly. I wound it fully on Monday, and it was still going great when I checked it Wednesday night. The only issue is that the works seems loose in the case. When I flip it upside down I can feel it "thunk" inside. It says waterproof on the face, so I am wondering if there is supposed to be a gasket inside (there isn't right now). Maybe this is what keeps the works from moving?

Re: 1967 Bulova (RE: Drb007)
Nice watch -- I have several. There are a couple reasons for a "clunk" in these watchs.
First, the movement can indeed be loose in the case from a missing locator ring, left out when the watch was serviced (or opened for some other reason). That style case usually has a stamped back that is held against a sealing gasket by a threaded ring.
Second, it may be an automatic (usually will have "selfwinding" or "automatic" in the dial, but not always), in which case the weight axle bearing can be worn, allowing the weight to clunk as the watch is inverted.
Easy to tell -- if the movement ring is missing, you can move the dial around with the stem.
I'd suspect an automatic if the watch is staying running for extended periods while being worn -- typically this type of watch has around 40 hours reserve time, meaning it will run for about 40 hours on a single wind. Some are 50 hours, but without knowing the ID of the movement, it's impossible to tell.
Bulova made wonderful watches in those years, very high quality. The only real problem I've personally seen with them, short of abuse, is that the gold fill wears off and the cases corrode badly on the back side. Movements are usually in very good shape, only needing a cleaning to restore them to like new condition.
