Cool watch. I did a quick search ......... (Views: 12)

with www.ixquick.com, my favorite seach engine, and put in CR2412. It
came up with lots of hits, even Reto's article on the watch and how to
replace the battery.

Be happy it's only supposed to be replaced every 10 years! >>> (Views: 18)

I have a Seiko Arcadia Perpetual . . . same movement. Also have Seiko
technical PDF on the movement which includes detailed battery
replacement instructions. The printing inside the watch back is
slightly mis-leading (aside from the "snort" misspelling). You're not
shorting the battery out in step 2, but connecting its + terminal to a
specific point in the movement circuitry.
I had my watchmaker do
the battery replacement (he works in a Seiko AD . . . among a few other
very high end brands) after reading the full directions in the PDF.
It's definitely more involved than normal quartz battery replacement
and you must be very, very careful not to damage the coil in the
process. There's also an insulator under the battery cell that must be
positioned correctly. For me, it was well worth the cost (about 2X
normal quartz battery replacement), which was still pretty low . . .
well under the cost of a replacement perpetual movement had I bungled
the job. The instructions are exactly correct that you don't have much
time to get the old one out and new one in . . . otherwise you must
reset the perpetual with day, month and year (in the 4-year Leap Year
cycle) which is a real PITA to get right.
If you don't have a copy of the technical PDF for the movement, PM me and I'll send you a copy.

Hey John! Found the 8F32 Parts Catalog - Technical reference PDF and guess where... (Views: 14)

Yup, Reto had it linked in his own impressive article.
I tellya, Reto..

All I've got is the Operating Guide for the 8F32. I found that PDF right off.. has one of the best Guide libraries! But.. ah, no I don't have the detailed service guide. PM coming!

I wondered about that. Usually snort-circuiting micro-circuitry is a very bad idea.

What are ye sayin', John? You don't think a Caveman Watchmaker can handle it?!

That's perhaps the most worrisome part. I mean, I'm pretty confident I can do
the job, just wondering if I can do it quick enough to prevent this
pesky re-programming. Obviously I'd like to forego that, if possible.
Thanks for the tips John!

Yup, that's a hard battery to find, you paid the going rate! Have fun reprogramming the calendar, it's a PITA! (n/t) (Views: 6)

...the entire back is one easy to access battery. Sorry, I think my springbar problem is much more difficult!
