Hello,

I just bought a vintage Omega Quartz (196.0066) with a 1310 caliber. This one delay about 15-20 seconds per day, the battery is a Renata 1,55V. Do you think that the battery is bad for this caliber ? According to my watchmaker the mouvement cant be repaired.

Thanks a lot.

The battery wouldn't be causing this problem, no. These watches have a trimmer, 15/20 seconds is high but if it's regular you could try some trimmer action to see if it helps. That type of drift is not normally indicative of a problem with the circuit.

Does that model,of Omega quartz have a trimmer? I am not familiar enough with that model, to know. I suspect the watch is stopping momentarily, creating the impression it is losing. If that is the case, adjusting a trimmer is unlikely to remedy the problem.

Yes the trimmer is the round thingy top right. You need a special key to rotate it normally but a small screwdriver can do the trick too. I think turning it left will slow it down, don't quote me on this though. I don't think the 1310's trimmer is as crazy sensitive as the one on the 15xx but don't turn too much.Without a quartz timer it's not easy to make adjustments of course.

Yes but with a very light touch, these things can break.

I'd send that watch to Omega. Just because a local watchmaker can't service it doesn't mean it can't be serviced.

Any imaginable question could be answered here:

But if I were you I wouldn`t touch that trimmer `cause it`s very old and made of ceramic which means it can break very easy.
You`re lucky to own a functional 1310 and there`s no replacement out there.
Maybe to maintain a service on the mechanical part of the movement do the trick.

For the battery: The original 354 had 1,35V and is no longer available because of it`s amount of quicksilver the replacement is the 301 with 1,55V.
Maybe you`ve to add an spacer because the 301 is smaller than it`s predecessor.

Replacement is the 386 actually...

Hi Archer,
I mean no offence since I`m a newbie around here but you can see on the following on your own:
Original battery according to Dr. Ranfft:

Original measures of 354:

On the other hand the 386 will fit also so you can choose freely.

The Ranfft site is often full of incorrect information.

Omega indicates that the 386 is the correct battery for this movement, so I trust them more that Ranfft personally, but you can choose for yourself.

I tried to explain that 386 and 301 are same measures.

That they are the same size means a lot less than performance, for example current delivery and capacity. There is a lot more to a battery than size and open-circuit voltage.

Just check my links above both are same capacity.

There is a lot more to selecting the right battery than the dimensions. As noted batteries have different sizes, shapes, capacities and they can be high or low drain, plus some other characteristics.

I'll edit this to clarify...Omega uses Renata batteries, and here is the battery specification from the Omega Extranet for the 1310:



As you note the dimensions and capacity of the battery are the same, but then why do they even bother with 2 numbers? Because they use different chemistry to achieve different characteristics.

The 301 is a low drain battery using an electrolyte that has sodium hydroxide in it. The 386 is a high drain battery that uses potassium hydroxide in the electrolyte. So although the cells are the same size and capacity, how they are able to deliver power under different loads differs.

Cheers, Al
