Also the professional divers I know tend to replace their gaskets every 2 to 3 years and have them tested.
Most failures tend to be at the crown gasket rather than the cashback due to neglect of that gasket.
For me, splashing around in the sea or swimming pool. The standard 3atm test, will be more than sufficient, after any work carried out.
If you are diving. Attention to your tanks and gauges are more desirable, if you wish to reach a ripe old age [emoji16]

These are the standards required.

The point is, a watch either leaks or it doesn't. I would of liked a better machine or even a Elma dry tester (Have you seen the price of them !)
If I was a serious diver my choice of watch wouldn't be the Rolex sub but the Sinn.
Same as if I were in the middle of nowhere in rugged terrain, my choice wouldn't be the Rolex explorer but the Casio g shock.
I once went under a waterfall only to be met by another and I was on the wrong end of it and literally had to fight the current back.
I forgot to take my watch off. It was a Swatch fitted with an eta 2841-1. No bar rating does say water resistant. Domed acrylic crystal. Never let in any water.
Haven't worn this watch for years. Just taken it out it's plastic bag and it's started ticking !

I've just ordered one of these testers. Looking on youtube how to use one. Says you have to remove the bracelet. This can be a real pain with solid endlinks. Do any of you guys leave the bracelet on and rig it somehow ?

Yes, leaving the bracelet is perfectly fine. All you need is to position it to be able to look at the back and crown to spot the bubbles, if any.

Also, testing above 5 or 6 bar , which is a lot already, is next to useless.

Some more testing.
Today I tested my Seiko turtle, mainly because it was running slow when bought this year, brand new from a dealer in Malta. And the best error was 0.7 face up. So I adjusted and regulated it. I did notice when it arrived, it was boxed but the watch had no wrapping on it. I didn't bother to change the case back gasket, so I thought I would give it a test. It FAILED on the crown gasket !
The second watch was a Rotary/ Omega homage. It has no water resistant rating but the bold statement on the dial (WATERPROOF) Thought that was not used these days !!! But by implication has an indefinite rating. It FAILED on the Crystal gasket ! The watch has never been apart.
Third was my 4 year old Seiko that's had a hard life. I've just finished a refurb on it. I used the old gaskets ! When assembling so thought I better test it. It passed with flying colours. My Skx did as well.
The point is, if going anywhere near water, test or have your watch tested, even if brand new.
I believe Manufacturers are reluctant to take liability on there watches, even if a certified diver. The test is considered valid on the day of testing. Best of luck getting a replacement watch after your watch stops after a couple of years because the movement has rusted up [emoji21]d143d2a007a811448a1d0f012f7a8233.jpg778eec72dffea6516a07004955cbe359.jpg

Every repair or bat. replacement on a water resistant watch will be tested dry on my ACL2000.
If there is a leakage I remove movement and test the case without movement wet to determine the location of the leakage. Mostly a filthy crown package is the guilty suspect.

Yep I think you're right. Now I come to think about It, when I first got the turtle I found the screw down a bit awkward. Never thought to take the stem out. Just put a bit of oil on the thread. Which seemed to fix it. I bet I've got a bit of crud stuck under there. Will take it out and clean. Thankyou

It's common for divers, even brand new, to leak one or three tiny bubbles from the crown tune, at 3 -4 atm already. That is not a complete failure and it does not prevent normal use at the beach. The solution is sensible application of silicone grease to the crown gasket.

Just to update. I've had the stem out cleaned around the case where there was a deposit of dirt where the crown sits. The stem and crown and gasket looked ok but put it through the UC anyway.
Just pressure tested and no more stream of bubbles. Job done.
Many thanks again for your help

It was more than the odd bubble [emoji5]

Got My Calipso Tester about a week ago and have read Mark's comments above - I just want to check I'm doing it right. 

I'm pretty happy with it - seems a good quality piece of kit and have got the gist of how it works.  Just want to check a couple of things.
 
Q) When you pressure up the machine with the watch in the top section, if the watch seals aren't good, it forces air into the watch case.  Should you wait a set period of time to allow this to happen - or do you move to the next stage (i.e immersion in the water) straight away?   
 
Q) If after immersion - on slowly releasing the pressure with the valve - is it VERY obvious that there may be a problem i.e. a continuous stream of bubbles exiting the case from the weak point?  When I've done it with a bezel still attached I have seen the odd beading (beading is the best way I can describe it) of a couple of bubbles forming.   Since then, I've been doing this with the bezel off in case there is air trapped around the bezel giving me a false impression of a fail.   
 
Also, has anyone seen - or got a link to a video of a failed test.
 
Thanks in advance, Jason

      Is this a 'hack' ?

      By nevenbekriev · Posted

      OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.

      Any tips to correct a sloppy error?

      Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.

      Setting lever spring

      By mikepilk · Posted

      The stress is the force (on the spring) x distance. The maximum stress is at the bottom, and decreases up the arm. That's why they always break at the bottom. I used a round file, then something like 2000 grit to finish. I gave the rest of the arm a quick polish - no need for a perfect finish. Just make sure there are no 'notches' left from cutting/filing. The notches act like the perforations in your toilet paper 🤣

      Any tips to correct a sloppy error?

      By Geotex · Posted

      It's probably a cardinal rule for watch repair to never get distracted while at the bench. Yesterday, after finishing a tricky mainspring winding/barrel insertion (I didn't have a winder and arbor that fit very well) I mentally shifted down a gear once that hurdle was passed. There were other things going on in the room as I put the barrel and cover into the barrel closer and pressed to get that satisfying snap. But when I took it out I realized I never placed the arbor.  When opening a barrel, we are relying on the arbor to transfer a concentrically-distributed force right where it is needed at the internal center of the lid. However, when that isn't present it's difficult to apply pressure or get leverage considering the recessed position of the lid, the small holes in the barrel and the presence of the mainspring coils. It was a beat-up practice movement so I didn't take a lot of time to think it over and I pushed it out using a short right-angle dental probe placed in from the bottom, but that did leave a bit of a scratch and crease in the thin lid. I had also thought about pulling it using a course-threaded screw with a minor thread diameter smaller than the lid hole and a major diameter larger, but that may have done some damage as well.  Thinking about how this might have been handled had it been a more valuable movement, is there a method using watchmaking or other tools that should extract the lid with the least damage?

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      🤔 what happens if lubrication is placed directly on top of epilame ? Making a small groove so the lubrication doesn't spread across the component but what if when lubing a little overspills and sits on the epilame .
