Hello, I have a SBBN033 Tuna. Would you say the crystal swap would be the same process as the one you just showed? Thanks

[@vintagewatchhunter]

Most of the Seiko's are the same, or similar. I wouldn't think there are many more parts to the watch that need to be removed.

[@vettedsin]

this should be the same process for the sbbn033 right?

I dove all of Hawaii for 20 yrs with my tuna always good to go. why would you say don't dive a dive watch no water.

Because once it’s been opened the gasket rings have been compromised and may not be water proof anymore.
If you open the watch the rings should be replaced for new and it should be pressure tested again to make sure it’s waterproof.
