Could I ask the collective, are barrel arbor jewels, parallel hole type or olive jewels type? Or are they specialised for this purpose?
Does anyone have access to Seiko jewel part number to size information please? Arbor, centre or otherwise?
I know 011123 is 240x150 (2.4mm x 1.5mm)
I think that 011142 is 160x100?
If anyone has measurements, please could you add them. Thanks in advance,
cheers, Dave. (not the cardboard box)

Did you ever find the answer to these questions? Also, do you have any insight on the Seitz or other jewels for the upper and lower Mainspring Arbor ports for the 6105 and 6309?

Thanks!

VTA do these jewels (if by "ports" you mean the holes in the plates). You can get them on ebay.

Thank you Paul!!! Yes, I've heard of VTA. Be well!!!
Adrian of Vintage Time Australia (VTA) does superb work. I have a 4S29 in for an overhaul and a 5740C 36,000 bph for repair with him right now.

He returned my early SpeedTimer 6139-6000 to it's original glory and offered to upjewel it as you say.

Highly recommend VTA.
