That’s one pricey battery………..

[ben4watches]

I do all my friends and families batteries, bracelets and straps for them and today I was given a old Seiko as it needed a new battery, presumably.

Its a Seiko perpetual calendar Cal 8F32, before opening it I checked the calibre specs on line as I always do to ensure I have the correct battery rather than replace it like for like with what’s fitted.

A BR2412 is required, that’s a new ref on me and £12 from cousins.

And don’t get started on setting the calendar, rather than using the crown it’s via a sequence of shorting the battery on specific areas of the movement depending on year/month/day.

Enough winging Ben and get on with the job, anyone got a spare BR2412 to save me excessive postage costs.

Never heard if that battery, but if that’s what it costs it is what it is! Love ‘em or loathe ‘em, Cousins are v. efficient at supplying whatever is needed.

New one on my too Paul, I’m surprised you’ve not come across the ref before given your extensive experience.

It would appear that the CR2412 is a direct replacement/alternative and have just watch a setting tutorial on YouTube and he has replaced the battery with a CR variant.

Don't order one yet, I think I've got a spare one at work. If not, my local timepiece is closing down and he's offered me loads of his over-stock at cost price.

Sent you a pm Kev.

But imagine how much it would cost if was a 'Rolex' battery........

I’ve used the standard battery before - think you’ll need to carefully need to remove and reuse the sticker that masks part of the - side of the battery

Thanks for the replies, I have one on the way now.

I think the sticker on the BR2412 is only there to indicate where to remove the battery, if you know the batttery release area then the sticker is not required.

Ive ascertained this by looking at various BR2412 batteries and the stickers are in various different orientations on the battery so there can’t be a specific area of the battery that needs exposing. The sticker lined up to the stem will give the correct area for battery removal and that’s all it’s for……………I believe.

I ‘think’ when you line the sticker up with the crown it lines up a hole on the negative side of the sticker that connects to a contact point on the movement- the sticker prevents other parts of the movement coming into contact with the negative side of the battery - I could be wrong though

That could be a possibility Lewie, I have seen a few fitted with the CR equivalent without the sticker but don’t know if this will cause issues down the line.

I have the Seiko BR on its way so should be worry free.

I was possibly being over cautious

A little update, new Seiko battery arrived today so to work I go.

I have never come across such a complicated watch to set, I know its a perpetual calendar and have done these before but 8F movement requires setting via a series of shorting the battery with various terminals o the movement.

If you are interested these are the new battery fitting instructions
