1970 Bulova Sea King "BX", 11blac. The case back serial number is 005958, the inside reference number is j-2682. The case is marked N0 and the movement is marked N1. This matches the 1970 Sea King "BX". Funny thing, I thought this was a Clipper "P". They look identical to me, except the clipper is mid to late 60s with the 11alac and the later Sea King has the 11blac. Again this is just my opinion from quick google data collection. Thanks for looking! This teardown is also on my YouTube, not a good video I mixed up the pause and record during part of the reassembly, haha.
Here's my YouTube video, if it helps...
