·Recently had my 2250.80 serviced and my watchmaker only charged me $250 U.S. for the He service...Watch Wt. after service 144g.
Big problem with helium escape

·I don't have a dive watch. Would adding helium to my regular watches make them noticeably lighter?
Heliox is a better option, but you will need to retrofit the watch with special set of gaskets.

·I have a friend that was a chain smoker, he unfortunately had one of these faulty valves in his Omega PO "Hindenburg limited edition" and it blew his whole hand off. Now he wears a non helium watch around his neck. Looks OK.
Okay, I'm calling total BS here - helium is NOT flammable. It was hydrogen that cause the Hindenburg Disaster. I know this because I studied the accident as it was the other biggest disaster to befall NJ on May 6th.

··Most fun screen name at ΩFI added mercury to this
And now it has the quality feel of my Speedmaster! It went from a puny 11.3 g to a robust 27.8g! Only problem - if you consider it a problem - is the conductivity of the mercury shorted the battery and fried the electronics...

··Most fun screen name at ΩFHey guys, is this a joke? Replacing air with helium won't affect the mass of a watch as stated the OP.
Here's an approximation:
Density of helium: 0.18 kg.m-3
Density of air: 1.28 kg.m-3
Difference: 1.1 kg.m-3
Case volume: 4 cm diameter x 0.8 cm = 10 cm3
Assuming the helium completely fills a watch case with 5psi pressure above atmosphere (or 1.3 atmosphere), we have 1.1kg.m-3 x 1.3 x 10 cm3 = 14 mg, which is over a thousand times smaller than stated above.
Am I missing something???
Yes , Pressure at depth and the fact that for watches they the much heavier He6 isotope.

That's what you get for owning a battery powered assault on horology. 😁

·Forgot to add my Breitling SuperOcean with auto He valve...a little heavier than the SMP @ 153g.

·Does anyone know what pressure I should use for a sea dweller? I know they are built for heavier duty so they could hold higher pressure, but is that true for both external and internal pressure? As I'm sure you are all aware they are very different things and I think this is an improntant aspect that's not being discussed.

·Between 5 and 10 psi seems to be the norm for Rolex overall. They are delivered with 5. Rumour says Comex were up to 12 as to cope with serious diving. The lighter weight was to compensate for heavier other equipment.

·I always get my watchmaker to fill my dive watches with sulphur dioxide. Just watch the queue I'm in disappear when I open the release valve.

··Nowhere near as grumpy as he used to be...As a long time diver here. The stories I could tell you.
Anyone hear about the tech diver that wore his new Omega PO inside his wetsuit on a deep sat dive? Whoops!
I also see so many problems with new divers not getting the helium level adjusted correctly in their watches. It used to be taught in the old manuals but with dive computers being ubiquitous it has been removed from the training. The process to adjust it yourself is easy once you know how to use the HeBS machine. (helium balance synchronizer)

··Bill @ ΩFDude, I think you should have chosen another Noble Gas instead of krypton. Neon is the much closer in weight to helium so it would have less chance of damaging the balance & pressure. Plus, it would give your watch a healthy glow.

·This is a beautiful thread. Reminds me the time that we went into a new boy's room at 1am, did a radon check in his closet with a lacrosse stick and told him that we had bad, bad news...
Poor fucker was doing nude jumping jacks in front of the dorm when the dorm master came out asking what in the hell he was doing.
"Getting rid of the radon!"
Still get a chuckle at the radon check.
