I’ve had 2 of the gold plated MKII Speedmasters and both came on a Time Computer 2? Bracelet with the last endlinks removed. Not quite what you’re looking at but maybe something similar.

The 145.014 came with two bracelets - ref 1162 and ref 1159. The ones that crop up at auction often don't have their original bracelets. The cases are often over polished, like the one in your pic. Here's an interesting article about restoring a MKII by Chuck Maddox.
I notice the hour indices on your dial are white - these would have been tritium originally, which would have aged to a yellow or greenish colour (the latter seems to be very common on these MkII's).

Omega service = expensive, but it would come back looking like it just left the factory. If you get a beat up mk2 for cheap, it's a viable option. Depends on what it would cost to acquire.
Here is a pic of my 1973 MKII Racing dial which was bought new by me 48 years ago. It was overhauled by Nesbit's earlier this year ($850, incl a case refurbishment) but still has the original hands and dial. You can see the aged color of the tritium. Crystal dates from its previous overhaul in 1980.
Unless the OP can buy that MKII very cheap it would be a hard pass for me. There are far better MKII's out there that would be better projects.
When I got the watch back I was severely disappointed. The case and bracelet were not restored. Turns out that the case had received a previous restoration and there was not enough material to do a full restoration/re-lapping.
