Which battery?

[RichardHarris123]

Anyone know what battery is required for this?  It was my father in laws, never met him , he died many years ago.  Obviously sentimental to my mother in law.

Can you measure the width and height of the battery compartment Richard?

Hi Richard. The movement shiojiri is from the Epson, Hattori  TMI, factory

the battery is probably a 364 or a 377 which is used a lot in their movements.  The Y1305A is not listed on the site I pulled up.

Not a 377, I'll measure the compartment later.  Tryed Goggling it, no answers

I think you were looking for the wrong movement, Y130A not Y1305A.

Batteries listed below.

The technical guide describes disassembly/assembly/oiling. These movements are £2-£3 on Cousins, so hardly worth the bother.

These have been discontinued for some time so not sure where you've seen them on cousins.
