Came across this watch on eBay tonight. Claims it was produced to 'compete' with the Bulova Spaceview and I'm not sure what movement is inside other than it is 'electronic'. Perhaps someone in this group can sort this out?

Such a cool movement. Three roller jewels on the balance, magnetic detent in the escapement, magnetic banking, and simple electrics. Relatively tricky to service.

These all have a poised sweep hand because the train is mostly just free, and a bump would move it otherwise.

So it contains the French built LIP R148 movement shown here ? Is this movement more along the lines of what the Russians were using in their 'electronic' watches ?

Yes it's the R148. The R184 is the same movement with date. These are considered "electronic" because they do have a semiconductor in them: a diode to suppress the spark that would eat the contact wires otherwise.

This is the first improvement on the early electric watches that had just a coil and contacts of some kind, like the Hamilton Electrics 500 and 505, whose contacts would wear away and need periodic replacement.

Later a transistor and sensing system of some kind will do away with the contacts completely.

Speaking of early LIP watches, I sold a super rare one a while back. A LIP R27. It came out in the late 50's around the same time as Hamilton. They were not mass produced like Hamilton so the interest in the watch faded. They were interesting as they were backset like the Accutron 214, but it used two batteries. Check this link out for more tech details.
