The Helium escape valve is used when carrying out work at great depths, professional divers stay in a diving bell for several days, breathing a mixture of gases containing a high proportion of helium. The pressure is gradually increased to reach the pressure at the working depth. The divers, still inside the bell, are then lowered to the working site. They leave the bell to carry out their work. Once their work is complete, they re-enter the bell, which is then raised to the surface. Pressure is then returned to atmospheric levels and this is when the valve must be opened (only for deep-sea dives lasting several days). The helium molecules diffuse and penetrate the material of the gaskets. The quantity is sufficient to push out the crystal during the return to atmospheric pressure. To avoid this, the Seamaster Professional Diver is equipped with a valve specially developed by OMEGA.
I love sweeping second hands. So I let mine run. Been 3+ years! No problems thus far, only thing I can think of is that at some point when it is serviced, it may cost a bit more. But considering it only needs service every 3-5 years depending on use, that extra cost spread over those years in reality is little.
Why you need service. I had a Hamilton and it has been more than 10 years with no service it is still working great. Why do you,need to,service an omega that does work.
I would love to see a video on the Omega Speedmaster '57 if you've got one in the shop. There's not too many good reviews on that particular model. Thank you!
R17D5D Hi, oh yes I have this beauty just arrived www.bankslyon.co.uk/omega-speedmaster-57-co-axial-chronograph-watch I shall be blogging about this next week
The explanation of the helium escape valve was all wrong. The valve is never supposed to be opened under water. The valve should be opened when the diver returns to the diving bell and is about to ascend. During decompression, the helium gas built up inside the watch will evacuate through the opened valve.
my wording was not clear, you are quite right you can not open the value at 1000ft it would leak I was referring to the build up of Helium in the case which needs to be released. Another blog with a correction I think, Thank you watching your comments are very helpful.
I had the speed master 125 anniversary well I don't miss it no more this diver watch is 3 times better, you never have to take it off, tuxedo to swiming suit sleep, shower and you will no be happy with any other watch . I'm loving it ! .
Somewhat bizarre to suggest that the column wheel has anything to do with the waterproofing. The column wheel is the mechanism for starting/stopping the chronograph .
Any chance of a review of the Aqua Terra Chronograph GMT with the 9605 movement? I am still back and forth about which chronograph from Omega to purchase.
Wanting to trade in my SMPO 8500 & Speedmaster (hesalite + manual wind) against yet another Omega..... thinking SMPO Chrono + pre-ordering the SM 300 (blue with wavy lines). Thoughts/suggestions please.
Not correct.The helium escape valve is only opened when you need to allow the gas to escape and ONLY when the watch is NOT in water and the while the diver is out of the water and going through decompression.
Tell this guy if you unscrew the helium escape valve underwater ( 6.00 ) guess what, water will rush in and make your calibrate 9300 all rusty and fucked. He doesn't understand the function
Hi Bob. I've just purchased this Planet Ocean Chrono, and I have to say this is the best watch I've ever owned. The movement is first class (what you'd expect from Omega) and its weight alone tells you it's superior quality. My Daytona has taken second place at this moment in time. What you get for your money on this watch is amazing! A watch for life that's for sure! Great review as well by the way. ;-)
Hey Duke, I'm thinking the same thing, my Daytona was too small for me, so I purchased this cool looking watch...should be recieving it This Tues, very excited. Do you still wear yours?
The Seamaster is my second favourite watch, the first being the Speedmaster Skywalker. Just ordered two skywalker's, so will have to wait 2 months till I can order two Seamaster's. Thank you for an amazing review. :)
Drew Smith I do agree. Rolex are superb watches, don't get me wrong. But I love Omega. I know that they are Swatch's baby, but the innovation of this brand is amazing.
Excellent video! It's nice to see a video on the De Ville as I plan on getting this De Ville Chrongraph soon. Please continue with all the great time piece videos. They are very informative.
This to me could be my one watch collection.

Helium release valves are for saturation diving, which is in fact done inside a pressurized dive bell, or a contained environment

More videos, please Bob! It's been two months since your last one.
I shall dedicate my next one to you, do you have a preference for a particular model?

Really enjoy all your reviews.!!

That Omega SPO Chrono is so gorgeous. One look and I think "Rolex who?" Just beautiful.
Datz wat i'm feeling right now..
Have both as I love the Deepsea James Cameron also. The planet ocean is a deal!
Great video Bob. This video convinced me to contact you to see if I can purchase the latest model Speedmaster Planet Ocean Chronograph.
Hi Bob,
Are you still planning on doing a Speedmaster '57 video?
Love your videos. It's been far too long since the last one.
Hi Bob, I was wondering how you could change the date.
That planet ocean chronograph but in orange is my grail watch

Obviously does not know his stuff lol
I do not even know what to take from you as a gift, Bob !. Both are great, I love these models Oega.)))

Man, you have great watches from Omega. And your Breitling is something!
Hezké představení hodinek OMEGA Planet a OMEGA De Ville, ale proč má ten člověk při tom na ruce Breitlingy??
Hi bob watch this channel all the time love the Omega deville chronograph watch
I purchased one 2017 exactly the same. How do I know it’s a ceramic bezel?
Great watch and great review!!!
is it also ok or allowed if you buy one that you get the exhibition back case??

Great video, sounds like a man who knows his watches!!
What do crocodiles swim in? ;-)
Dead ones don't tend to last all that long in water though :D
What watch is Bob wearing?
Breitling SS Chronomat

+dukeofpearl I Got the Planet Ocean Chrono on a blue strap and it's just utterly amazing!! One of the most exquisite timepieces I have
Hey Duke, I'm thinking the same thing, my Daytona was too small for me, so I purchased this cool looking watch...should be recieving it This Tues, very excited.
Do you still wear yours?
Very nice you give a good talk
About the watches I think I will buy one now thanks
Very nice and informative video. Thank you
He is the look-alike of the boxing promoter Bob Arum.
The Seamaster is my second favourite watch, the first being the Speedmaster Skywalker. Just ordered two skywalker's, so will have to wait 2 months till I can order two Seamaster's. Thank you for an amazing review. :)
better then rolex any day
Drew Smith I do agree. Rolex are superb watches, don't get me wrong. But I love Omega. I know that they are Swatch's baby, but the innovation of this brand is amazing.
The planet ocean is £6,700 today
Excellent video! It's nice to see a video on the De Ville as I plan on getting this De Ville Chrongraph soon.
Please continue with all the great time piece videos. They are very informative.
what watch are you wearing?
i believe he is wearing a breitling
Hi Matt, I was wearing a Breitling Chronomat...schoolboy error, I should have been wearing my Omega de ville hour vision that day :)
Bob Breden Many thanks. I now am the proud owner of the 45.5mm planet ocean chrono. I went with the orange 12. your video was what convinced me!
+Matt Finley Why not white 12?
Yeah, you would ruin your watch immediately, if you opened that Heli relief valve while diving at depth
Best watch ever 👍
Water resistant not waterproof
Omega has some nice classic designed watches. They should stop producing new retro designed watches and stick with the classics
sorry but the seamster does not go well at all with a suit. no sport watch does. maybe breguet marine
You're a tool. My omega looks great popping out of my shit
Might be better if you tried to make it a bit more boring with less gusto and enthusiasm I nearly dropped off to sleep
