Hey guys. I finally located my late grandfather’s watch and band and he has swapped in a Wittnauer that I’m not familiar with. It needs a new battery and service but I can’t seem to open the case. What am I missing? It has an arrow next to the “base metal” engraving And it seems that passed watchmakers have taken their case knife to that spot and to another spot on the side to try to open it but there doesn’t seem to be a gap there to open it with. I tried my case knife and it won’t grab. And I’ve tried to get it to unscrew but it won’t budge. Before I do some damage what am I missing here? f8756afa7dd6f5dc92180df76c1ac2a5.jpg7b613329e51b62f50c441d25886f905d.jpgb0149ee520aa9dc56b6f98d70b559c39.jpg

I think you just need a fine edge and a steady hand, there are plenty of cases out there you simply can't open with a conventional case knife.

Some of those are just very hard to get a start on, without a good gap to get in to. I’ve used a single edge razor blade on a few. You could be required to tap the protected edge of the razor with a wood dowel as well. Then suddenly it will pop off. Afterward it will most certainly require a back press to press it back on. Not pretty or very professional, but without more expensive equipment and experience, necessary.

Thanks. I removed the front bezel and can’t remove it that way. A few of my watches open that way. But not this one. So with the back I have now tried a knife and a straight razor with a plastic mallet with no success. So I guess I’m gonna have to take it over to a pro before I cause damage. Strangely I have never had a problem with a case before out of my 50+ timepieces. But thanks for the help.

That's an interesting watch. The case looks like a remake of a sixties model that needed special wrenches, 1175, 1200, 1260, that were marked with that instruction. I just worked on my nephew's from the early era, and had to take it out through the front. I used a syringe at the case-tube and blew off the crystal. I then used a crystal vise to replace the crystal. Looking at the back, that would have been my first guess. But his had not bezel, just a back and a crystal.

I like your case. The bezel reminds me of one of the nicest looking Wengers I'd seen. The dial is quite nice, and it's fairly obvious that it's a later manufacture than the 1960's. Are you looking at the back under good magnification? 4X or better would be good to verify that the back pops off where you suspect it might. One thing we know is that it comes through the front or the back. In other words, the movement wasn't assembled like a ship in a bottle, through the case-tube. :D

I have encountered this style of case a few times & they can be bloody tight.You will need a good snap back case back opener.

Unfortunately my laptop is broken & I have not yet found  way to save a pic with this mini iPad.!,,,,

 

However here is a vid of the opener I use for the tight ones.

    • Thanks for the answers. In my case space is very limited: I only have the kitchen table on evenings. This is why I am considering a mostly water-based system (keeping heptane only for balance complete and pallets) and no cabinets, no big machines. Any advice for water-based detergents that I could procure from Sweden (ordering from Cousins is OK especially for non-hazardous liquids because normal shipping would be used). Should I really get an ultrasonic for those or would it also work by hand? Thanks!
    • I'm glad it worked out well for you. Must feel good to learn some new watchmaking black magic huh? 😂 Can you post a photo of the crown after all this, I'm a bit interested in how it looks compare to how yellow it was before, never thought alum could dissolve oxidation as well, maybe I can work out the chemistry behind it, something to do with the electrochemistry list, but I'm too lazy for it so 😂 you are lucky it was only yellow, the layer must be so thin it didn/t damage the finishing enough to be noticeable.
    • Thank you Andy, I will keep that in mind.  Fortunately this time, I tried to drill the stem out before finding out about the alum method, therefore most of the stem was hollowed out.  When I took the crown out of the third bath, I was able to screw the whole replacement stem in.  It us now in the ultrasonic cleaner to get any remaining gunk out. claudio
    • I haven't been on the forum for a while 🙃 A family member had a 955.112 watch running with an intermittent fault. Bought a NOS 955.112 movement, but to be sure, I'll give it a full service. It has been a long time since I did the 955.112, so I went back to @VWatchie walk-through ........ Again, I'm struck by the quality of it ❣️ Superb work 👏 🫶 🙏
    • Hi Neven , Agree we you that guard pin is in general a suspect , but OP replaced the fork, no joy.  Perhaps roller is damaged or misses the guard pin, so OP is going to check the escapement with high magnification &  adjust end shakes as well. Regs
