I don`t get the 'LOL'.....??????...someone asks for help/advice and hopefully someone can provide it. That's how things (usually) work on this forum.

I`m not familiar with the movement, but here's what I`d do. Estimate the dimensions of the battery space using a digital caliper, then look up the dimensions of available batteries and choose one that matches up. If the OP looks on google this info is available, I`ve used it myself in the past.

Alternativeley, post a detailed photo of the movement and someone may be able to help.

They are apparently 26mm dimaeter;



I would guess from the hole that it isn't a non-standard battery, so I would just buy a selection card of the cheap, nasty watch batteries from ASDA or Tesco for about 99p, find one that fits and then use it to order a decent one online ;)

Lithium button cells are named according to their dimensions (diameter then thickness) so CR2430 is 24.5 × 3.0 mm. Something like that might do. Can't find one that is 26 mm though.

edit:- looks quite deep so maybe CR2450?

If the seller couldn't help you, maybe Ronda themselves (http://www.ronda.ch/en/ronda/) can?

But according to "Battery Bob" (whom I am not affiliated with in any way) , a Maxell 370 or 371 (the dimensions and voltage are the same) is the one for this movement (if "Ronda Harley 113" is the same movement!):

There are many cross reference charts on the internet, this is just one of them:

I hope this helps - good luck!

Could there be missing 1 contact? I only see the + this might be the reason you can't find a 26 mm battery. Battery might be less then the 26 mm due to the missing contact.

The movement is 26mm diameter, not the battery!

Omg, I'm just reading back my answer..... rather stupid. Wasn't realy paying attention to the mm. Sorry for that. But still....missing a contact in the picture?

I think the top bridge is one point of contact and then there's a connector on the left side (if you can talk about sides in a ring).
No idea about the exact battery though.

Edit: can't tell left from right.

Its sometimes worth searching images on the net.
I do it for some of the more obselete older stuff if I have no reference and am unsure.

Works on the assumption if you can find a couple of shots of the movement from seperate sources with the same battery then its probably the right one.

I should say, its not always 100%...
