Seiko Modding Reference

Post by Watch Noob » February 9th 2021, 8:26am

Dug this old bookmark up from WUS, it's a handy cross reference of some popular Seiko models. If it's already been posted, my apologies.
https://www.watchuseek.com/threads/diy- ... 01.466199/

Fits for the basic Seiko divers: 6105 / 6309 / 7002 / 7s26

Hands:
all hands on all Seiko Auto's are a fit ...

Dials:
99% of Seiko dials are 28.5mm in size, if you cut the pins off the back of the dial most dials will fit each other but you will need to use glue or tape to fix the dial to the movement ring

6309 dial have a small tab at 2:00 to keep an eye out for ...

6105 will fit 6309 but not the other way since the 6105 is date window only
6309 7002 & 7s26/7s36 do not fit each other ...
6R15 dials will fit 7s26 movements but like the 6106 the 6r15 is date only window
And so a custom no date or no day/date 7s26 dial will fit a 6r15

Glass:
6105 glass will fit 6309 & 7002
6309 & 7002 glass will not fit 6105 because the 6105 needs a domed glass for hands to clear ..
6105/6309/7002 does not fit 7s26 divers ...

Chapter rings:
I think 6105 and 6309 chapter rings fit but all others are different ...

Bezel inserts:
6105 6309 7002 are fine the 7s26's might need a little trimming we're talking mm's in size to fit the other but basicaly like hands all fit ...

Crowns and stems:
to keep it simple they don't fit each other with out a little modding ..
7002 crowns fit 7s26 but the stems need to be changed

if you see anything wrong or have a few more tips feel free to ad to the post ..

PS:
the 7002-7039 diver is a transitional diver from the 150m to 200m rating it is a true odd ball and parts fit the new 7s26 divers not back to the older divers ...

That is awesome, thank you. I always did a search and looked through tons of threads to get information at WUS. This needs to be a sticky.

Glad I could help. As I'm tearing down my Seiko's, I kept thinking, (and now measuring), "hey these look like the same size" between different models. When you go to purchase parts, you can get 3 different reference sizes for the same item on different sites and it gets frustrating.

Good idea to post this - not a lot of modders here but some

The best place for crystal info, at least for modern pieces is USA Crystaltimes, they don't necessarily have a cross reference but when viewing a crystal they will reference all the other watches they know it will fit.

For example the top hat I got for the turtle mod I did

https://usa.crystaltimes.net/shop/model ... rts/ct096/

And copied from their site

"Material – Sapphire crystal
Type/Design – Flat Vintage “Top Hat” look/shape
AR* coating options – Blue AR, Clear AR** and No AR
*AR coating is underside only
**Clear AR additional 10 usd
Ref dimensions – Dia 32mm Total Thickness 5.8mm
Suitable for – New Prospex “Turtle” 200M SRP773 SRP775 SRP777 SRP779 SRP787 SRP789 SRPC44 SRPC23K1 SRPC25K1 SRPC49K1 SRPC91 SRPC95 “PADI” Versions – SRPA21 SUN065 – Blue Lagoon SRPB09 SRPB11 – Dawn Grey SRPD01K1 – Save The Turtle SBDY021
FLIGHTMASTER – SNA411 SNA411P1 SNA413P1 SNA414P1
SOLAR 200M – SBDJ009 SBDJ011 SBDJ013 SBDJ015
PADI SOLAR – SNE435 SNE435P1 SNE493P1

DAYTONA – SNA225
Suitable for NEW 62MAS – SPB051 SPB053
Additional info – Vintage style “Top Hat” flat sapphire, for the buyers who require more of a vintage look to their mod, very popular for the Soxa Mod."

As I come across any other info I'll add it to the post :Thumbsup:

That's always a welcome help when looking for crystals. When I bought a crystal for the 6309 I ordered 2 to have a backup if I cracked it. Little did I know at the time it also fits a 7002 which I changed out as well.

Thanks for the tip Mark and yes, feel free to add.....
