Seiko 6309 vs 6349

[Jonno65]

Hi All

I just stripped and reassembled a Seiko 6309A movement and I have a 6349A - I haven't started that one yet - just curious if anyone knows the fundamental difference?

Cheers Jon

Jewel count. 27 vs 23. The 6349 is an update on the 6309. Escape and pallet changes too.

Thanks Richard - funnily enough I was looking and I saw a jewel which wasn't on the other!

Cheers

Jon

Oops,  I got the jewel count wrong, typo but the rest is correct. 

[Jonno65]

No worries! Actually I just stripped it.  I can see the jewels around the mainspring barrel and others - notable improvement.  probably could have deduced that after all - but good to know. Cheers

Jon

The Jules Borel database (julesborel.com ) is useful for comparisons. It will tell you which parts are common

For those interested, I made a guide for how to use it some years ago.

EDIT:

Just remembered it. Here's possibly another good source: https://www.emmywatch.com/db/

Thanks Mike, great resource.

I have a 6349a movement turn apart with missing pieces that, one day, I'll try to restore it .Since I have a 6309a movement laying around, that might turn to be a donor, since plenty of pieces are the same according to julesborel.

Sorry for the reply to a several-months old thread.
