Today I'll be changing the gasket on my Seiko Tuna that had the bezel turning very lite when I received it, making me think something is wrong.
When I removed it I noticed the rubber gasket was broken with a piece missing, so I ordered a set of gaskets for the 7548 and 7C43 Tunas and here I show you how to replace it
The SBBN015 is one of my all time favorites as it comes on a great bracelet and has a beautiful black bezel. Powered by the legendary 7S46 high-torque quartz movement it is considered one of the best quartz diver out there.
I hope you enjoy :)

As always excellent tutorial, however I'm really surprised how easily the 1.5 mm shroud screws unscrewed......I've removed at least 3 shrouds......and all were a pain!

That's because I already removed them initially when I was cleaning the watch, before I ordered the gasket

Does your bezel have one or two click springs?

Does this o ring provide any water resistance or is it just traction for the bezel?
@WatchGeek
@WatchGeek 4 ай бұрын
Just friction for the bezel, the crystal has its own gasket for water resistance

Nope, the 300m Tuna is quartz and thus powered by battery
