The 371 is the low drain I believe and that is the one I have used. If the fit is tight, then a 373 which is thinner. Some brands mark their battery "370/371" as well, so there is probably little difference between 370 and 371.
Wanted to suggest the same thing. I am cleaning the gasket and apply some silicone afterwards. After that I go to the watch shop and let them check if the watch is still waterproof...
I find the pressure test thing a bit difficult for this reason: what if it fails? Do they just give you a water logged watch back, "sorry buddy, turns out it wasn't waterproof"! At which point they need to repair it and you're where you would have been if you just started using it and it didn't work out. If the process is followed correctly, it's probably not necessary.
A proper pressure test should look for air leaking out of a pressurized watch and not result in damage. That being said, I think with a well-made watch which is not subject to deep submersion/diving, the chance of an issue is quite low.
@@omegawatchfan I watched a video on it just now, seems they pressurise with the case out of the water and then submerge it (briefly if there's an issue). I was thinking any air that escapes will be dispaced with water, but probably not if done in this way.
Thank you so much I'm in the uk and went to a shop today and they wanted 90 pounds to change the battery! I said no thanks...I have the same watch as this one..I want to change the metal strap to a leather one...I wonder how hard that is?
Yes 90 pounds sounds crazy...I imagine they would change the seal and pressure test as well for a price like that...for my regular day to day use, I don't need all that and would rather save the $$$. It is fairly easy to remove the bracelet, you just need a good spring bar tool to compress the spring bar. I like the Bergeon 6767, which is what I use. Definitely worth spending the $15-$20 for it. I would recommend practicing on a cheap watch because at first you will make some scratches, but after a while you will get the hang of it.
Sometimes, the watch is fine. I believe there is some mechanism to protect the watch in case of a drained/low battery, but if the battery has leaked it could cause damage to the movement. You can see if that has occurred when you examine the battery.
I think they are very hard to come by because of Omega limiting supply, so it probably makes to have the watch serviced by them. You could substitute the generic ETA equivalent, which I think would cost in the neighborhood of $100, but I think it's best to keep an Omega all original.
@@kyle_vr Yes they do, but it and the original Omega movement is completely serviceable. What I did on mine was I got an ETA 255.461 from Esslinger as a parts movement. I replaced the date selector wheel and the circuit board and retained the Omega baseplate and geartrain. Works perfectly. The 255.461 is made of brass and looks quite different in appearance compared to the 1538. But all parts electronic and mechanical are swappable between them. As long as you don't swap the movement plates you can't notice the difference. The 255.461 was $129
thank you for posting. i am planning to change the battery of my Seamaster.
Excellente video... thank you for the information about the 371 vs 395 battery
Glad it was helpful!
Thanks for your video, it really helped me.
Glad to hear it! Thanks for watching
Thanks for the video. I heard you should use the 370 low drain battery compered to the 371 high drain for use in chronographes?

@@omegawatchfan Thank you for the reply👍
Put some silicone on your case seal next time it doesn't take much and will preserve the rubber.
Great tip, I will use it for the next one.

Am I the only one that goes scuba diving with a scuba diving watch 🤨
Haha perhaps. I used to wear a Citizen Orca for diving, it was titanium with a rubber strap and very legible.

Makes sense they found a way to do it without ruining your watch 😄
Yes, but the thought of it is still a bit nerve-wracking to me!
it takes a 370/371 dual drain battery. either one is fine ETA movement is 255461 1538 is the caliber movement. change the O-ring too
Thanks...did not know that. It is definitely a good idea to change the seal for sure.
i got my omega case key tool from ofrei

@@davegill7614 Hi, I uploaded a video showing how to remove the bracelet, in case you are interested.
@@omegawatchfan thanks matey..
@@alwayspooh1588 I think it's the pressure testing they charge the money for....I took mine to the local indoor market lady did it for 5 pounds :-)
Thanks for the video. What happens if a battery has been fully drained and sitting like that for several years?
Sometimes, the watch is fine. I believe there is some mechanism to protect the watch in case of a drained/low battery, but if the battery has leaked it could cause damage to the movement. You can see if that has occurred when you examine the battery.
How long will it take from the low battery sign until the watch completely stops?
I have seen some of them work for several months in the low-battery phase. It should work at a minimum for a month, in my experience.
How expensive are these movements to completely replace?

@@omegawatchfan Does the ETA (base of the 1538) fit and work in a Seamaster?

Tool name to change battery
It is a generic caseback opener, there are 3 prong and 2 prong styles. 3 prong gives you a bit more control.
Oughhh that's not good ,
