Hello guys

Im currently working on a 165.024 seamaster 300 and want to get it waterproof again. Therefore i need new gaskets for the caseback and naiad type crown. Also i‘m interested if its possible to get a Service bezel from an Omega certified watchmaker and how much it costs. Maybe also Service hands

Greetings and Thank you in advance

What's up Buddy

Unfortunately, the O-rings in the Najad crown is not intended to be replaced, they are pressed in to place during the manufacturing.
So if you want your piece ready for some action, you have to replace the crown for a new one...

You will find the crown and a full sword hand set here... and some other stuff that you might need in the future...

Good luck,

Regards

I used g30873 o rings from cousins for the crown. Of course 2 of them. It seems to be flush but i didn’t do a waterproof Test.
