Swiss Sentinel movement removal

[Cogs64]

Hello,

This is my first posting on any forum of any kind so please be gentle with any obvious questions I may put forward.

I am new to watch repairing and have only stripped down a dozen or so watches. I am having difficulty removing the movement from this old Swiss Sentinel watch so that I may clean and oil the watch. The crown came out easily but I cannot see any obvious screws that hold the movement in place. I have tried gently plying at the movement with tweezers and screwdrivers to get some movement, but without success. Any thoughts or suggestions would be greatly appreciated.

Looking at the photos I think it’s a front loader, you will need to remove the bezel and crystal to get the movement out.

Hello and welcome from Leeds, England.

Welcome to the forum.

Does the ring around the movement with the slot by the crown not come out?

[Cogs64]

Thanks for the quick responses. Regarding the watch being front loading the case seems to be a solid piece with no removal of the bezel being available. I have taken a better side on image to illustrate this.

@AndyGSiI have tried lifting under the slot by the crown using a screwdriver, I too thought this to be a solution but getting absolutely no movement.

Have you tried removing the crystal? 

[Cogs64]

No I haven’t had a go at the crystal as yet. I’ll give that a try in the coming days and let you know how I go. Thanks again.

Hi. Could still be a front loader held in via the crystal. Try as Richard said ,

Hard to be sure from the photos but it looks to me like there are places for case clamps to go, but no case clamps. (Don't know if that adds much to the conversation.)

I also thought it looked like a removable ring around the movement. One of my Bulovas has a similar-looking ring that can seem pretty secure but then with a bit of wiggling it suddenly lets go.

Thanks for the great feedback. I’ll be back in my little workshop in a day or so, and I let you know the outcome.

Thank you for all the responses. I turns out that when I applied a little more force than usual to the opening next to the crown, the whole movement and dial popped out. It was just wedged in there a little harder than expected. I nice result and experience from my first post
