I thought it through the hunt continues looking at a Seiko 6105 or Bulova Sea King(early 70s)
A 6105 is great but certainly not "cheap", you might spend between 500 and 1000 USD.
Better off keeping an eye out on offerings here, and another option is to find cheap 1980s Seiko models like 4205 or 4206.
If the latter, just make sure you're getting the right size for you and if you buy from Asia be careful as movements there may have been highly corroded by humidity, and call for expensive repairs. You need to find one that works and keeps time.
Not really a great idea, but I know a friend(watchmaker) who waterproofs watches
Agree with the other posters those are all terrible. Go with a cheap citizen or Seiko if you really want to find a cheap diver, besides you are going to wonder what to do with a 10 dollar watch that needs a 200 dollar service one day.
Happy to hear it and post some photos
Nice choice. I think you will be happy with Seiko at that price point
Don't go too cheap on the hammie, the service may cost you more than the watch
