Phinney Walker Mickey Mouse Watch HELP

[Stoller5]

Hello everyone,

Being new to the forums and to watch repair in general, I was hoping to get a bit of help. I own a watch exactly like the one below

https://www.ebay.com/itm/405149477307

It winds, but does not seem to run. I'd love any help figuring how to open the case (i think there might be a small space on the top 'bezel' where I might be able to pop off the crystal, but would rather have guidance first.

Many thanks,

[AndyGSi]

I'd expect a similar notch somewhere around the rear to pop that off.

From the same listing, the back side:

I would guess that the back pops off rather than the front. You can see a little groove there where the caseback sits over the winding stem, rather than a case tube. Look for an indent or notch around the back. It might be possible to pry this off from almost anywhere on the back if it sits right against the rubber strap.

The movement looks like it is from the Ronda RL family (015 or 115 or something? I forget which numbers have a calendar and which don't)

I have no experience with this watch, but looking at the pictures from the ebay listing linked above, it looks like the outer metal bezel at the back of the watch may not be part of the case proper. 

It looks like the watch and strap are sandwiched together, and an inner case may push out of the rear bezel towards the front of the watch. 

A case style similar to the Roamer watches where the crystal, movement and caseback pushed out through the back of an outer bezel, only in reverse - this one may push out towards the front. 

To test this, you would need to hold the watch, dial down, supporting the dial side of the watch around the edge of the bezel without touching the bezel itself.

Then push down carefully on the inner metal ring you can see at the back of the watch.

I’m speculating here, proceed at your own risk.

Hopefully someone with hands on experience of these watches can chime in!

Best Regards,

Mark

It's an exhibition back so no access as you suggest.

Thanks everyone for jumping in here! I appreciate all your knowledge

Hi there Stoller, 

 Caliber is generally stamped under the balance or thereabouts. 

Caliber can't neccessarily be identified by bridge layout.

This eBay listing seems to verify that the watch disassembles as I suggested : here.

The display caseback is held by the section that pushes out of the outermost rear bezel. 

The movement seems to be a Ronda 1113.

Best Regards,

Mark
