I own a 300m vintage from 1960. This is a great way to find out on how it works. Not sure if I would do it thoug.
Just my opinion. Thank you for a great presentation!

 

Very thorough step by step, I was able to learn something new as well as see a failure, ty

 

is there a model name for this equipment Arches or is it a diy ?

 

Assume you are referring to the high pressure equipment:

Thanks a million Archer for the Step-by-Step tour of Water proofing. It must have taken much time to have done all the procedures. It sure brings me lotsa pride after reading your post every time i read my 2500's "600m" knowing the rigors this beautiful piece went through to earn those words! God Bless!

 

I'm down for that. Destructive testing used to be my day job.

 

Interesting; thanks for posting

 

Such a great insight @Archer Thanks for taking the time to give us yet another “peak behind the curtain”.

 

so cool and professional testing!

 

Great info. I had no idea how much kit was needed to do this properly.

I had not clue this is how watches were tested for depth/pressure. Thank you for sharing.

 

Great step by step. It puts your pictures when you send to customers in perspective

 

Thanks for sharing, your posts are always very detailed and make it much easier for regular people to learn the efficient way. Thanks

 

Thanks for sharing ! I always wondered how a proper pressure test worked ! Did it ever happen that water got in a watch during the last pressure test (with movement/dial in) ?

 

Not to me...

 

What longevity should be expected from modern gaskets ? I've seen a few example of flooded divers you posted in another topic because of lack of maintenance, how often should we have our gaskets changed in order to avoid that ?
Once again cheers for your helpfulness.

 

Follow the recommended service intervals from the manufacturer - servicing a watch is about more than just the movement, as gaskets are replaced at each service.

Also get the pressure testing done at least once per year, preferably before the time of year where the watch may get more exposure to water.

Cheers, Al

 

More than fascinating look at P testing. Thanks a lot!

 

Very interesting and super valuable to get a step-by-step guide on this from a well-regarded watchmaker around these parts.
