Looks like a Quartz Seamaster from the Quartz boom era (60s-70s). . . I am sure someone else can be a little more specific though. . .

That is an f300hz Seamaster "Cone"
Tuning fork powered, smoother sweep than ANY mechanical, accurate to about 2 seconds/month and were SERIOUS expensive whan new...... the other Seamaster 120m (with bakelite bezel) version was more expensive than the Ploprof in its day,
heres a Cone from Youtube....

Nope, not even the parts for the original Bulova movements are available anymore, the parts that usually fail are the coils on the tuning forks, the datewheel (the teeth get chipped away over time unless well oiled) and the index wheel which has a microscopic 300 teeth that are "pushed" by jewelled pawls attached to the base of the tuning fork which vibrates at..... 300 times a second. Bulova, for whatever reason destroyed the only machine capable of making the index wheels sometime in the early 80ies and stocks are reduced to the odd nos package on ebay and breaking up donor watches to repair the more expensive/collectable ones.
The movement was a Bulova and licensed out to everyone from JLC to Tissot.

The movement in action under a strobe ...............
