Tissot case back removal

[bosstaki]

Hi guys! Does anyone know how to remove this case back on my Tissot 1853 automatic! I’ve tried what I could! Cheers

What have you tried?

Is there any indent around the back?

Hi it’s probably a snap back. I have found Tissot backs very tight and need a case back tool to clamp the movement and pry the back off. Conversely you will naad the case back press to get it back on again.  Both on eBay or Ali Express.

There’s no indents & there’s no little groove to pry it off anywhere! So I don’t know if it’s screw down or pry off

For me the text looks too aligned and with no obvious way to grip as a screw back.

The case back is perfectly aligned to the case and has no provisions for a screwing tool. The T-Sport series has snap on backs.

The ones I have opened also do not have a pry point , hence the reason for the tool. The watch is clamped in the tool and a blade is screwed into the seam, the blade being chamfered lifts the back then the screw shaft is turned and the back comes off have a look on Ali express for case back removal tools

I'd just use a standard case back hand tool with either some Kapton
tape or the silicone paper from the back of a label as protection.

It’s it one of these I need to use mate!

Yes that's the type @watchweasol is referring too but I don't like them as you don't get any feel to what's happening.

It's not really shown here , but the blade flips over, so it faces the other way. The knob and threaded case holder then pushes the caseback seam into the blade. Once the blade starts to penetrate into it, the lever and blade are lifted , which should hopefully pop the back off. A lot of fashion style cases have very tight seams and need a sharp blade to start separating them.  Don't buy the cheaper plastic versions of this tool, the posts with the pins through for blade holder break easily if the apply extra force to blade.

Here is a method described in the watch repair book of Mark W. Wiles. Don‘t hammer, just tap very gently!

Another option:

This is a method that Jon uses, and has posted a video of performing it somewhere .
