Old Battery replacement table

Hello everyone,

I think I saw once a thread on batteries for vintage Omega quartz movements.

I remember the thread explained that batteries once used on vintage quartz movements are no more available due to a change in the type of batteries and there was a table explaining what the modern replacement for old batteries was.

If memory serves me right they were also paired with a list of movements for which those batteries would work.

I’m asking because I finally went back to my place and noticed that some of my vintage quartzes are in need of a change and since I’m respectful of the community etiquette I am posting a picture to show part of my collection (others are elsewhere unfortunately).

In this picture you will see, left to right:

  • Marine Chrono
  • TC2
  • TC3
  • Speedmaster LCD 186.0004
  • Speedmaster Polaris “split second” 386.1232
  • Chrono-quartz “Albatross” 396.0839




I feel like each one deserves a proper thread and presentation, I also don’t like showing them in non working condition.


The other models that I don’t have handy and will also require battery change:

  • TC1
  • Mariner 196.0054
  • ref 396.0850
  • ref 582.0001
  • f 300hz “lobster” 188.001


Thanks a lot to everyone for your help, I tried a couple of searches also via google but couldn’t locate the table I refer to.

IMO you should keep changing the batteries regularly or take them out if you would leave them in store for a long time. Rotten batteries can damage the watch. Bring them to a specialist for a fully check maybe a good choice. Btw a nice collection you have here 😀

Yes good point,

i always promise i'll wear them in rotation but some of them hardly get wrist time in the time their battery works, i'll just choose one and for some time will wear that one only

Hello everyone,

I think I saw once a thread on batteries for vintage Omega quartz movements.

There are at least a couple of threads on this site.


From those threads it is apparent that things are not always as simple as one would wish. For example, reference 2511.41 (cal 1438) was apparently designed for the original Renata 395. However, at some point Renata changed the physical dimensions of the 395 battery, decreasing its thickness from 2.6mm to 2.5mm. As a result Omega updated the service bulletin for the 1438:

Due to a manufacturer-related modification of the battery shape, the positive battery contact cannot hold the new batteries safely in place and there is a risk that they will fall out after a shock to the watch. For this reason, the 395/399 battery is no longer recommended for Seamaster 300m and Aqua Terra models with calibre 1438 or 1538.

The 395/399 batteries are to be replaced by the thinner "Renata 371" battery and, a limiting spring Ref. 722520010601 should be added.

Interestingly, other battery manufacturers have apparently maintained the original (2.6mm) height for their "395 equivalents." So, if you want to replace the battery in a 2511.41, you have to determine whether or not your watch has been modified with the additional limiting spring. If there is a limiting spring, use the Renata 371. If there is no limiting spring, use a non-Renata "395 equivalent" such as the muRata SR927.
