Hi Folks,
OK...I'm a Noob when it comes to Home Brew pressure testing for water resistance of watches.
I made myself a Home Brew Pressure Tester as found in the link.
When pumping things up, I had a hard time getting the lid tight enough to pump past about 75 psi. I used a Nalgene branded bottle.
I tried to follow the instructions as found in Water Resistance Testing.
At 75psi the following reps seemed to pass fine:
Ulysse Nardin 45mm Marine Diver Cheapo Omega SMP Rolex Milgauss
I tested my Breitling Skyland, and there seemed to be small slow bubbles forming around the chrono pushers but no fast leaks...so this seems to me that it would likely be fine washing dishes and some splashes, but probably not the best for prolonged swimming...definitely not for diving.
Does this sound right?
The Milgauss was funny...tested fine...no problems...but a couple minutes later, condensation formed inside, and a couple more minutes later, condensation was gone.
Rats. Something is not right. But, what does this mean??
I opened up the caseback and stuck it in a baggie with silica gel to dry things out...I'll test again later...but who knows.
Any suggestions?
At 75psi, do you think this would be fine for swimming? This seems to my understanding, that 75 psi = 15 psi for atmosphere 45 psi added = 50 m / ~165 feet water resistance or hopefully fine in a swimming pool but not diving
Is this right??? Thanks for any help.
