I need the CR2412 with the plastic/paper insulator/conductive strips on them.

Is there any other place that has them other than Seiko? I am ASSUMING that when I tell Seiko 8F35 and SBCM023 they should know to send me the battery with the strips on it, right? They want $15 for the battery and $7 shipping.


Now. Should I be worried?


I got my watch 1/2011. It may have been floating around for 6 months before that between two other owners though it was in box as new, sealed, when I got it.


It's gone back and forth twice now between "Normal" and the 2 second advance. It stayed stuck on 20 (Date) for 3 days (doing the 2 second deal) before it went back to 1 sec advance and the correct date.


It looks like my battery has only lasted 4 (or so) of the EIGHT years it should have lasted. My battery date tick on the rear is between the 4th tick of 17-18.


How worried should I be?


Much Thanks in advance,

A search on Ebay for 301A 95N0 will show genuine Seiko batteries for a few $ less than what you've been quoted. No idea of freshness, no connection to the seller, not an electrical engineer, professional driver on a closed course, your mileage may vary and I only rarely stay in a Holiday Inn Express.

I am not familiar with the numbers you searched on.

Here is the battery I ordered from Seiko a couple hrs ago.

http://www.livesaysinc.com/newItems/CR2412.html

Here it is for $2 cheaper than Seiko. For $2, for this use, I'll stick with the factory.

There Are Panasonic CR2412s that are only the usual $3-4 but they don't have the insulation area the stock battery does.

This watch is too hard to replace and the changes Are Supposed To Be 8 years apart. I decided not to take any chances.

I'm STILL a bit worried that an 8 year battery only lasted 4 years but I guess the major objective at the moment is to get the battery replaced before it dies and the perpetual calendar has to be reset. (PIA)

I wouldn't be too surprised if teh battery comes without the insulator. But you can remove the one on teh existing battery and reuse it. I have done that many times.

Sorry - how do you know its only lasted 4 years?

If it is correct then 4 years is low. Most of mine last a good 10 or 12 years. But it could have been a dodgy/old battery that was in it

Thanks Noddy.


thianwong, I had seen an earlier version of the same vid, yours is a better, clearer version.

Barry, I hear you but you only have 3 minutes with the battery out to get the insulation off the old one and on the new one. I'd like to not have to reset the perpetual calendar if I didn't have to.

On the age, First, the factory puts a dit mark on the back when they think you will need a battery, mine is just shy of (20)18. I bought it from a member here in Jan of '11. He got it from Another member here but only held it for a couple days before offering it to me. It came sealed in Blue still. I don't think owner #1 had it but for a few months. This 2010 time frame semi jibes up with the factory dit mark just shy of 2018 for a 8 year battery. [EDIT;] I am presuming the battery going bad here is the original battery.

Yes you can get a Seiko battery 301A95N1 from Jules & Borel. Just order the battery they have listed as a CR2412 and they will send you a Seiko OEM battery with the insulator already attached. This is the one I have in my inventory that I ordered from Jules & Boral



According to the tech manual this battery should last 8 years in the 8F35 movement. It has a shorter life in other and as long as 10 years in some other movements. There is a very specific way the battery has to be installed on the perpetual calendar watches otherwise you have to reseat the whole watch if you don't.

Goo dto see it comes with the sticker.

I have heard that one gets 10 mins before they need to be reset. But tbh i have removed and replaced batteries that were giving the 2 second tick, in less than a minute and still had to reset the watch. But the reset procedure is not too bad.- there are down loads around - but make sure you get the right one as some make it more complicated than others. I do about one a month - and it takes about 4 mins.
The worst thing about these are getting teh old battery old and the new one in.

Its easy to damage the coil when getting it out . And just be careful to get the 4 or 5 retainers in teh correct position when putting the new one in.
