What you have the is a Incastar Regulator system.  I have attached images which explain and show how the regulator works.

It actually says Incastar on the dial . Thanks for sharing . It's for sale on ebay but i would like to build it up if i had a nice case for it . Probably has been a gold case for it as i bought as a movement . Somebody has melted down the gold for the money . To bad .

One of the interesting aspects of watch repair is the discovering of variations. Not just case variations dial variations the hands but movement components. The watch companies seem to have an endless supply of ideas of how to do things giving us an incredible quantity of things to torture us with. Although I'm not sure they were actually specifically designed to torture the watchmaker they can end up doing that.

 

So the links below have additional information lots of pictures lots of variations of using this regulation system. The third link if you scroll down far enough has a picture of the inside of the case back which has the setting instructions.

Then I've attached a image for an advertisement for another system called a triostat

    • Hello and welcome from Leeds, England. 
    • Hi watchweasol, yes that is a way of doing it I suppose, I have a pair of mainspring hole making pliers on their way off eBay, the ones with the different shaped punches. I may be able to use them to make a hook.
    • Hello everyone, Glad to be here. 
    • This is a modern watch, the crown is definitely made from solid 316l steel. You must have heated the crown to some 200C caused the surface colour to change to light yellow. It's similiar to steel tempering. Yes it is the chromium oxide that forms during the heating that gives rise to the colours you see as you know stainless steel contains chromium. The fact the crown is SS lead me to a question, you've never heard of the alum method? Because alum would work perfectly in this case, instead of drilling, which, there is always a risk of damaging the crown, I would just let the crown chilling in some warm alum solution for 1-2 days and the job is done.   Sure can but the thing is the crown is not just mirror finishing, the lock symbol is polish while its background is some sand-blasted finishing so it would be hard to replicate that. You can buff it all shiny but losing the sand-blasted finishing means it won't look exactly like before.   Gasket is always tricky to me. I would try to use some gasket that look closest to the broken one in term of thickness and diameter, and check if the replacement gasket fit with some friction to the case tube. Lastly you can still use alum at this point.
