Default Seiko 6138B vs 6101

Hello,

I ma new to this forum and the reason I am here is that am looking for parts to complete my seiko panda movement (6138B). I am specifically looking for all the parts that compose the automatic module, so I discovered that the 6138 is based on the 6101 and from what I saw on some videos on youtube there are some parts that looks exactly the same.

These are the parts that I need:

(can't post pictures until 5 posts)

And according to this video (from 20:10), I think I can rescue the oscillating wheel and both parts that are on my second picture.

(can't post link until 5 post)



...Anyway, can anybody comment on the compatibility of the automatic module between these 2 movements?

Welcome to SCWF.

Do have a look at the technical manuals / watch parts guide for both movements - there you'll find the part numbers for the needed parts. Write then down. If they match the parts from the 6101, you can substitute them.

The 6138 has the 6106 as the base caliber, so you might be better off with that. I think we have both in the library.

Used parts for 6138/6139 are easy enough to find on eBay.

Are you looking for the whole automatic assembly? If so, you will want the bridge from a 6138B as it will have the correct movement number.

Thank Mr. Jones for your help, I looked at the technical manual and the parts number aren't the same, it's a shame because they look the same.

Anyway, While I was looking at the manual I noticed there's a part that I can not find, maybe you can give ma a hand.

If you go to youtube and look for a video called "Seiko 6138 0011 chronograph P1" from "Doctor Watches N Clocks" you can see at 20:52 a sort of jaw that holds the transmission Wheel, he take a picture of it with his phone.

I can't find that part on the manuel anywhere. Could you take a look please and tell me I am wrong, I can't look for that part without the part number.

"As for all other parts not shown here. please refer to the basic calibre (Cal . No. 6106A 25J Catalog No. 61-06-1 Green page)."

831611 - Pawl lever with jewel
Is this what you're looking for? It's Seiko's "Magic Lever" for bi-directional winding.

do you know of movement holders have parts numbers too?

I am looking for one for a panda and I am not sure if others might work too.

I guess they are in the casing part list, as it is not part of the movement. Sorry, don't have a number for you.

For 6138 cal movement, you want movement holder S-501. You can purchase one of these from Adrian over at VTA, Vintage Time Australia that works very well. He has a ebay store. I just finished a restoration on a 6138B movement and this is what I used to set the hands.

Thanks but I meant movement holder ring that goes inside the case, it's for a 6138-8020.

I also need to know if it require a spring like this or not.

Yes, the 6138B has a movement retaining ring similar to the one you show in your pic.

is that the holder ring you need or the solid ring that goes around the movement, that prevents it from going side to side?

He needs the solid ring as well.
The casing spring is available from member daveeb on eBay. Just not sure if he has the correct size springs available.

I actually need both rings, seikosis on ebay told me he has one and will upload so I can buy.

I am rescuing this panda that has a lot of missing parts.

There's a chrono hand missing on my watch, should I replace all of them with a new set from seikosis or just replace the chrono hand?

Will a new handset affect the value of the watch?

I think it will effect the Value. Better to have Five OEM hands and One AM imho rather than all AM Hands. Your Question was about VALUE and that is what Im thinking about Your panda looks very Nice and If you do get to Buy the set, Keep the OEM hands for the day you may want to Move her and offer them with the watch. Good Luck nice panda.
