How does this one open?

I’m not sure so this is guess work. A case knife around the red arrow edge. Alternatively, what looks like a Rolex grid mark around the case green arrow, so you will need a case opener that would achieve it?  I do not think it comes out from the front.

Thanks....I have already tried the green.I will shoot for the red. I can't see how it could screw down and I agree that it probably wouldn't come out through the front.

    • So I managed to get everything together and got my first readings using a standard stereo pre amp I bought for a turntable several years ago. Sadly i still didn't manage to get my diy microphone preamplifer kit  to work (the one i mentiont in one of my earlier posts). At the moment I think about ordering a already built preamplifier board but I do not have the qualifications to judge with would do the job (or at least would lead to better results then with my current solution.  That's why I am again counting on your help. There are some pretty cheap options but I don't know how to judge the all over amplification from the specifications given. My current preamp has the following technical specifications: Input Impedance 100kOhm, 5mV, Output Impedance 100kOhm, 250 mV, S/N-Ratio: >50 db, 12V DC, 100mA The options I'm most into at the moment is something like that cause its cheap and and may be an improvement (however I'm not sure about that) https://www.ebay.de/itm/TDA2030A-Audio-Power-Amplifier-Board-15W-AC-DC-12V-Assembled/292336674126?hash=item44109fa54e:g:nUAAAOSwKrhVZbo1:rk:28:pf:0 or even simpler: https://www.ebay.de/itm/TDA2030A-Audio-Power-Amplifier-Board-15W-AC-DC-12V-Assembled/292336674126?hash=item44109fa54e:g:nUAAAOSwKrhVZbo1:rk:28:pf:0 There are more fancy options like https://www.gearbest.com/other-accessories/pp_009478010615.html?wid=1433363 or https://www.gearbest.com/other-accessories/pp_009478010615.html?wid=1433363 but I have absolutely no clue if they would be suitable for the task at hand. The thing is that (as you surely have noticed by now)  do not know the first thing about electronic. But I'm eager to learn, I just don't know where to start. So thank you for your time cleaning my mess.   On the bright site as I said, I managed to get my first signals and I'd link to share some pics of that:
      This is my set up at the moment and some readouts from two of my watches (I hope it's okay to post the watch-o-scope screenshots). Today I broke the piezo trying to replace the cabels between it and the jack with shilded ones and now I have to get some more piezos to get my DIY-timegrapher running again. Let me know what you think and thank you very much!
    • Great website pointer jurowla. I've been on the search for options regarding my Seiko SKX007 and that site will definitely provide some options. If you wish your watch to remain original, 7S26 movements are still available new and as they were produced by the bazillions, many donor watches are available if you opt to go that route.  Our favorite on-line flea market has numerous examples of both watches and movements for you to acquire if you like. 
    • Thank you for your introduction and welcome to this friendly forum.
    • One observation I made is that very small movements are less forgiving than larger ones when it come to pieces of lint, etc.
    • Could you provide a good clear photo please.
