Thought I'd share how I was able to remove the plastic shroud from my 7C43-6020, keeping it in one piece (phew!). I read this thread first, which suggested putting the shroud and case in very hot water, but mine seemed quite flexible still so I didn't bother.
Disclaimer: The following steps...
I am looking to purchase a black chapter ring with white markers for a Seiko Baby Tuna. Like those used in the Seiko SRP227, SRP637, and SRP639.
I would appreciate any suggestions on where I can purchase one.
