Unknown Type Gasket Traser P6506 Watch-Case

[Endeavor]

Hello All;

 

I opened a Traser Commander P6506 case, which supposed to be watertight till 200m/660ft. For reasons unknown to me, the gasket under the lid went missing. There is a gasket groove in the housing which has, with my best measurements, an ID of 30.1mm, an OD of 32.4mm and a depth of 0.9mm.

I have no idea whether is was a round or square gasket.

- Has anybody any information about Traser watches gaskets?

 

if none;

-What would the best guesstimate gasket size & type be?

 

I don't have any facilities to pressure-test the watch, main thing is that it gets rainproof or better.

 

I red Cousins UK is the place to be for ordering?

 

Hope to hear.........

If there is a groove it is a round o-ring.

Cousins UK will have the exact size or a very acceptable one.

With new gaskets (crown has one too) and a smudge of silicone grease there is no need for pressure testing, even for pool use.

Thanks jdm!

 

So it's a O-ring. Does one order the ID as nominal size? Would that in my case be an 30mm? Thickness 1mm or thicker?

[jdm]

O-rings are rarely thicker than 0.9mm but it seems your watch may need 1.0 or 1.1. If you are not sure or can't find the exact diameter size order the next smaller one as you can easily stretch it a little to fit.

The lid is flat. So if the 0.9mm O-ring doesn't protrude above the groove, I guess no seal?

The ID is 30.1mm, OD is 32.4, so a 30mm ID O-ring, with a 1mm thickness would be 32mm OD. Still 0.3mm left for deformation when compressed.

Does that sounds fair enough?

[jdm]

Yes I've corrected my post, check above.

I'll check with Cousins what they have. Thanks a lot jdm !

Has anybody by any chance some Traser info, as cross-reference?

Thanks in advance !
