Seiko Tuna bezel gasket replacement - fixing a loose bezel

[@twhite7900]

Hey! Great video. I can’t figure out how to reduce resistance on my 1000m sbbn042 do you have any recommendations? I’ve disassembled it, lubricated, but still stiff

[@pibblesnbits]

Best iteration of the TUNA!!!! Hope you kept this one!

[@MicroAngelo1]

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!

[@WatchGeek]

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

[@brucesoding9627]

Fantastic - I love this watch. Have you thought about doing a crystal upgrade?

[@WatchGeek]

Yes, but we'll see if I go through with it

[@ammaryacine5502]

Bonsoir, where i can buy a Safire crystal for my Seiko tuna?

[@WatchGeek]

Crystaltimes from UK has them

[@ammaryacine5502]

Thank you

[@LiveTorsionParadoxTo]

I did this. It was scary but it worked. Thanks - you just got a sub!

[@jairusblok1511]

Does this o ring provide any water resistance or is it just traction for the bezel?

[@WatchGeek]

Just friction for the bezel, the crystal has its own gasket for water resistance

[@jairusblok1511]

@@WatchGeek I have a seiko prospex ships limited tuna, can you please tell me where I can get a replacement bezel gasket from? Or if it even needs one?

[@RampartPh]

is that a good brand of lubricant?

[@Inkushu]

Does your bezel have one or two click springs?

[@whatsonthewrist]

Very helpful video! 👌

[@cma2380]

Still looks pretty loose to me. The only way to fix a misaligned bezel is to remove it and then glue it back in the correct spot the springs are not adjustable so no other way to do it

[@superjjfire23]

Misaligned and loose are not the same thing

[@slammersam924]

Thank you ! 👍

[@upan3259]

Why not go one more step further and change the crystal?

[@WatchGeek]

I didn't have the crystal, but most likely will do it as well

[@mikeryan5217]

great video, thank you!

[@williamhill7312]

Great video

[@user-sungpark0217]

awesome big brother

[@swish1onu]

Bezel rotation on that tuna seems way to loose..

[@clo2715]

Kind of looks like a seiko bottle cap without the shroud.

[@WatchGeek]

Yup it does 😃

[@jerstolp1]

love the mm.. u said battery.. im pretty sure its a automatic. ie no battery

[@WatchGeek]

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

[@larvancioramos9748]

Jumping jesus, i almost die with the pop click

[@johnmilner7603]

The shroud looks like crap on that watch. Shame on Seiko.
