Seiko 5106A Transmission Wheel Missing

[JBerry]

Hey folks,

I recently purchased a Seiko 5106-7000 from Japan for repair, it was listed as running, but with a defective calendar mechanism.

I started disassembling the movement to find that the Transmission wheel is missing along with it's accompanying screw.

The part number is 505.001, and I can't find it anywhere, does anyone have any idea where to source one?

Thanks in advance!

Maybe buy a 5126 to take parts from?  Like this https://www.ebay.com/itm/Seiko-5126-7000-for-parts-restore-Serial-nr-7503402/113199419654?hash=item1a5b361106:g:SJYAAOSwUAJbcaVM&frcectupt=true

Same wheel.

Great idea! That's what I'll do, didn't think of the related calibres
