Well, this months pick.

The circuit on this are almost bullet proof . Remove the screws and take the circuit out . Clean the underside and all the contact areas. Check the coil. They are usually the problem when not running. Maybe that some parts from the corrosion has come in to the wheels . Then you need to take apart and clan the to. It's a pretty good movement that could run for years. Only need to change the battery every once in a while. Usually once a year.

Excellent, well done.

Congratulations! Isn't it great when you can always glance at your wrist to see the results of your work?

Thank you. Im very excited to find a group where I could talk shop. What’s the fun in restoring a movement or replacing a 1mm jewel if I cant talk about it with people who understand the accomplishment of learning a new skill.

Today was my 1970s Zodiac Super Seawolf

So it's time to take the watch into one piece. It seemed to be easy so I have started - hour hand, minute hand, zeroing chrono, minute recorder hand, hour recorder hand and the last sweep second chrono hand. I zeroed the chrono, attached position, pushed it down. I think great - it's done I started the chrono and after few seconds tried to zeroing. Pushed the reset button and .... what the heck? : -s Pusher was hard. I was affraid to broke any lever so decision could be only one - disassemble movement again: - | I took over chrono bridge and cleaned it with all reset chrono levers. Small amount of fresh oil and voila - works. : -! All that was left was to press bezel with crystal, put the new gold plated bracelet and have a enjoy of the watch. I know it's not pristine, have some drawbacks but I feel proud to back this one to life. I enjoyed some much during this project. I hope You too.There is still accurate tuning and amplitude measurement but it must wait until I buy a new microphone for timegrapher. I am sure I will inform You about the result. So stay tuned.

You are very lucky to have all of those. I only had a few. Having the correct tools for particular work makes it easier, these days many specialist tools do not come cheap.

OK, here are the bad boys. The curving ones I have go from 00 to 5, the lifting ones from 00 to 4. The example hairspring would be about right for a deck watch- very big, and the largest of both sets worked well. You can see in the 4th pic that the end of the lifting tweezers can be adjusted for the thickness of the spring (red circle) and how far it pushes (screw in blue circle). I just did a simple overcoil, there are many shapes, here the goal was to get the curve to follow one of the spirals more or less imagining in our imaginary watch that would be where the regulator lies.

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!

Hi All, Can anyone please assist with what ultrasonic cleaning solutions are available in Australia, what are some of the better solutions, if rinse solutions are also required and where I can obtain these solutions in Australia. Also if anyone can advise if Zenith Radiant product 777 is available in Australia and where. I am relatively new to all this and must be some kind of a Muppet as I have searched the internet high and low and still as confused as I was when I started. Would greatly appreciate any advise anyone can give. Thanks Phil
