This watch looks like it is a hodge podge of parts, case back is 3440 and would appear to be for 2210 movement, caseback is dated N5, Movement is dated N1. The dial is a Snorkel 666. The amazing thing to me is that this watch is pristine. Any comments appreciated.
Jack Hope this is the correct place to post.
At the moment my thinking is simply an Accutron 'SNORKEL', or perhaps an 'Oceanographer' but I'm not sure if they came in the Accutron line.
I do suspect, like you, that the case and movement are not original to each other. I'm seeing examples of this case with manual wind movements of the same era.
I think it may be an Accutron Snorkel in the wrong case. I don't have any specs to back this up, but I don't think an Accutron dial would fit a mechnical movt,* or do we have an example of such a thing? More likely the works have found a new home in this case.

*That's assuming the dial hasn't been simply glued on to the movt, I have seen that too often.
