Can't get the movement out - Zodiac Hermetic

Question

I assumed it was a so called "monocoque" no back watch. Pulled the crown, it broke.

Opened the glass but still can't get the movement out. 

Any ideas?

Hi  That back looks to me as though it can be removed. look round the perimiter for an indent for inserting a case knife if none visible you may need a case crab like the one attached as some of these cases are tight.    can you post close ups of the case edges it may help.

In most cases one would find the slot to open a snap back case approximately 180 degrees from the stem.
The reson for this is to avoid the winding crown and case lugs beeing in the way, if it been serviced the slot might have moved in position due to a lazy watch repairer.
Then there is these "tight" snapbacks like Tissot and other uses then a tool like shown above will work.

In the thread below I posted about "Seiko style openers". That is what one wants in most cases.

I believe the tool  you posted is meant to be a bezel remover, with the flat side of the blates being on the case side once the watch is placed upside down. Otherwise two blade would be always in the way of the lugs or band. Some examples in the thread above.

Safety razors works for removing both the tight and not so tight snapbacks. if it turned out to be one of tight fit you would need a tool to press it back on, regulare types can be pressed on by just hand.

You think so? Hope you'll never need to get off a really tight, contemporary Swiss "tight case back" using only a razor blade, as you would end with a broken blade, or worse.

I guess I am talented, never broke one. :P

I don't think so, a razor blade does not have the shear resistance to lift the many kilograms. It's made to cut, not to pry. Just make sure to wear anti cut gloves when experimenting that branch or metallurgy.

    • Hi Just out of interest, was the broken part of the balance in the packet with the roller and the rest of the balance.   cheers  
    • Hi John and welcome to the happy factory
    • Even though your package is opened I don't suppose you get a picture of the bits and pieces of the package for us? Then a caution factory packages or basically the paper envelopes that typically watch parts come in except balance completes usually come in very special packages but any of the paper envelopes always require caution because it's standard operating practice for a lot watchmakers to put the old part back in the package.  Often times they didn't label that it's the used parts sometimes they do.
    • Hi all, Hopefully I'm on the right forum this time!  Thought while I was struggling getting my first project back together, I would try a pocket watch as I'd read they were a bit easier, so I bought this off Ebay. I've fallen at the first hurdle as I can't work out how to get the back off! Don't think it screws off, as I've tried without success, so thought it must prise off, but again no luck. I don't want to apply too much force, just in case it actually does screw off. Anyone any experience/thoughts on this please.    
    • A really nice website for American pocket watches once you have a serial number is found at the link below. Also nice with Elgin watches the parts list is available there. I don't suppose you can get another picture of the movement preferably the angle? It may just be a lighting issue but I'm not seeing the hairspring for the balance wheel? I can see the stud it still there somebody rotated the regulator all the way to one extreme is interesting?. They hairspring may be hiding under the balance bridge but it's I'm not seeing it?     https://pocketwatchdatabase.com/search/result/elgin/9785822
