Omega Seamaster 300M

[Shotgun Jon]

Need a new battery in my seamaster. I've been quoted £105 by beaver brooks for the battery but now they have said they won't change the battery unless I have the watch serviced for an additional £215.

I'm in staffordshire and wondered what peoples thoughts were? Good a normal independent jewellery do this job and seal the watch properly?

Thanks

Hi,

You'd be better of fitting the battery and sealing the watch yourself IMHO.

Cost to fit battery shouldn't be no more than £5-£10 and water resistance test £10-£15.

If you can confirm the across caseback holes are the same as below I can send you a non marking omega case opener.

I have no affiliation or experience but they appear to be a long-established family firm and they have an in-house watchmaker. I'd discuss with him and ensure that they can reseal the watch case and pressure test if need be.

IMO unless the Seamaster 300m is used in a REALLY HARSH environment(s) the buna nitrile
caseback o-ring which is rather sturdy probably about 1mm cross section and 36mm inside diameter
shouldn't need replacing.

I'm pretty sure they are about right so I'd be very grateful if I could take you up on your offer! :-)

A watch like this really needs to be looked after properly. You may well be able to take it apart, stick a battery in and put it back together but if anything goes wrong when it's in pieces you'll be stuck. More likely is that you won't re-seal it properly. The case back is sealed with rubber gaskets that can perish, so the process of opening the case back up can be the end of them and they often need replacing. Even if you have sealed it properly, you'll soon find out next time you go swimming in it and then you'll have a real cost on your hands when it's wet inside!

Ultimately, you own a decent watch that probably cost you the best part of £1000 or more so a few quid getting it looked after properly is worthwhile I think.

Chaps,

Omega Seamaster bond caseback gasket code 088.5143NS is about £10 from Cousinsuk.

Did they test it first before telling you it needed a full service?

They might suggest this as the watch isn't holding a charge in the battery meaning it does need a service? Most places are about 65/75 for a Omega battery and seal.
