I have been getting gaskets and 'O' rings from Cousins, they have a large selection of generic sizes and profiles plus OEM too. mountapo_merchant has provided caseback gaskets for 6309 etc divers pretty cheap, not !00% correct fit but they do the job for desk diving.
Sometimes its best to bite the bullet and pay the odds for the correct gasket and make sure it fits and does its job, especially for crowns and pushers.
The 7C43 hands have different size holes compared to Seiko mechanical watches, I do not know where to source them from, if they were mechanical movement size I would paint some 6309/SKX ones.
