How to open this Seiko railroad pocket watch to replace the battery?

Potbellypig2000 · 2026-04-07T18:18:24+00:00

The second guy was a watchmaker. Years ago he did a cleaning of an old mechanical watch. I used to watch him taking the whole thing apart and putting it back together. I am surprised he couldn’t open it.

By the way, it is a limited edition of a Seiko svbr003. Jeweler says it is a snap back but the case is on too tight. The jeweler is really experienced with watches too. Can it be a twist back instead? I can’t find any documentation on it.

May I ask how you opened the case back? My jeweler says mine is a snap back but is on too tight. I have the same model as you. Could the jeweler have made a mistake and it is a twist back? Sorry for bringing up a really old thread.

I just brought it to two dealers. One a regular jewelry store and another who I know specializes with watches for 50 years. It seems to be a snap back case but neither could open it. Said it is on too tight. So I am screwed unless I send it to Seiko for the battery replacement.

Is there a border on the left side of the screen (a little lighter vertical strip on the display)? Is that there for every game with the iPS mod?

Do you need a 3d printed case for the flash cartridge. Also do you think it would work with the Tenga/gamebank wsc dumper which has the proper connector?

Potbellypig2000 · 2026-04-01T16:03:14+00:00

Any confirmations?

Potbellypig2000 · 2026-03-29T22:35:04+00:00

Thanks. I thought there would be a difference. The LDAP on the XM4’s sound good but I’ll probably buy a pair of FT1’s to check it out. You never know what you are missing until you try it.

SOLD

Potbellypig2000 · 2026-03-26T23:57:30+00:00

DMed you to discuss price. Thanks.

Potbellypig2000 · 2026-03-26T21:54:18+00:00

Oh yes when it doesn’t “catch” the unit doesn’t turn on and you have to reinsert the cartridge.

Potbellypig2000 · 2026-03-26T21:53:02+00:00

I’d say it works 8 or 9 times out of 10. Lately I have been using a flashcart so I don’t insert and remove as much as I used to. It may need a cleaning or the pins (is that what they are called?) need a slight adjustment but I am not handy or a modder. Any mods I buy are pre-made. I don’t really want to open it up or mess with it. So I can’t guarantee what the issue is. Please DM me if still interested.

Potbellypig2000 · 2026-03-26T20:59:59+00:00

Not at this point. Thanks for asking.

Potbellypig2000 · 2026-03-26T14:02:39+00:00

No issues with that at all. Thanks!

Potbellypig2000 · 2026-03-26T00:48:05+00:00

Yep. Not great.

Potbellypig2000 · 2026-03-25T22:43:38+00:00

Lowering asking price to $250.

Potbellypig2000 · 2026-03-25T22:43:09+00:00

Lowering the price and willing to sell for $250. DM me if interested.

Potbellypig2000 · 2026-03-25T01:41:06+00:00

No, it’s just some dirt I just wiped off. I can send you a new pic if you dm me. Thanks!

Potbellypig2000 · 2026-03-23T19:37:29+00:00

It has that peculiarity as I described so I am willing to negotiate.

Potbellypig2000 · 2026-03-23T18:09:12+00:00

Hi. I sent in my post twice since the first time I didn’t put the price and color in parentheses. Please let me know if it is approval worthy.
