What is the model? Setomatic? Where do I find the Serial number?
If it has a s/n, it will be on the inside of the case back. Date code will also likely be there as well. If not, the movement should bear a date code. Set-O-Matic appears to be a feature, with the watch model just being a number like this one. 1978 is a good guess, image below is from 1977 - 1979 Linebook213

Cool. Movement appears to be dated "N8" for 1978. We don't have a lot of detailed info on late 70's watches in Hong Kong produced cases and many had no s/n or case date code, so they have to be dated by movement date.. I would guess that "R-302" is case style number. Thanks for adding the interior photos.

Nice work Bob. Based on the previous ID I agree with a 1978 Bulova Set - O - Matic "11680"
I like it, pretty sure this is an "international" (not originally sold in the states) model. 1978 Bulova Set - O - Matic 11680
