1967 Smiths W10 - what mainspring

[stefan_in_LA]

Hi All,

I just acquired a 1967 Smiths W-10 and am going to service it near future.
To that end, does anyone know what mainspring goes into it? (I'm hoping to be able to get this info before actually stripping it down...) catalog number, specs... anything would be helpful.

The movement is a Smiths 60466E movement.

Any info would be greatly appreciated.
Thanks!!!

Christian (https://watchguy.co.uk) lists a GR4536 mainspring as a suitable replacement.

John Senior at http://www.obsoletewatchandclockparts.com could have original correct ones. Great watch, congratulations.

THANK YOU !!!
This also seems to confirm that the 60466E is essentially the same movement as the cs.27
This is very appreciated information!
