Hi everyone and thank you for accepting me. I'm a teacher and recently got into watches, I'm about to turn 50 and treated myself to a nice watch. I got a Momentum Torpedo Pro Eclipse - Solar [44mm]. But it stops working whenever I wear it!! Take it off and set it down, works fine, put it on stops after 15-30mins????? Momentum sent me a replacement but I'm curious why this would be. Any ideas?

There are a few people that have static in there body all the time. I'm not saying this will put it right for all but a small round plaster stuck on the back of the watch, so between you and the watch no direct contact sometimes works. So give it a go and let us know.

Hi and welcome to the WRT forum.

 We all are Mr STATIC,  Oops I sure hope your students don't read this . 😂 lol

 As we walk specially if one drags his foot on the ground/ carpet..... etc . We collect static electricity in the capacitor our body is, as our body  contains many  elements which charge no $ fee to host charged electrons.

I've heard about this before, I dont think it was static related though, something else going on in the body. I was permanently static charged as a kid, my dad constantly getting me in a headlock and rubbing his knuckles on my head 🤨.

I'm one of those. I have an extremely low skin resistance and at those funfair strength testers where you grip two metal rods to test your "strength", all I have to do is lay one finger on each rod and the meter goes off the scale, the lights and alarms all go off.

I recently changed a new pair of sneakers and the insulation must be really good because I store up a charge very quickly and touching anything that is grounded will give me a slight tingle. And this is in Singapore, where it's so humid that static electricity hardly ever builds up.

But coming back to the watch, I don't think static electricity can affect the electronics as the metal watch case acts as a shield.

The possible explanations I can think of for the puzzling problem is

1) Temperature - it could be your body heat is causing a bad solder joint or contact point open the circuit. You test this by heating up your watch in an oven or with a hairdryer. 

2) Movement - it could be a loose contact that opens when jarred around.

3) Gravity - it could be a loose contact that comes open when the watch is no flat on its back.

Thank you everyone. If the cause was static wouldn't that effect other watches? I've never encountered this before. 

HectorLooi's 3 reasons sound plausible. Sounds like it would be repairable.

Many thanks

    • Thank you Mike for the hints! I did go to HS Walsh and buy few tools that will help me start 🙂 I also went to the Royal Observatory at Greenwich, I saw the collection and it is amazing!! Harrison H4 is indeed an amazing manufact, and the story behind it (about the prize from the government) is incredible. Again, thank you for your suggestions, you made my day!
    • Hello watch enthusiasts, I'm encountering a peculiar issue with my Seiko 4006 movement and could use some advice. Specifically, the alarm bolt yoke doesn't function properly when I tighten the screw on the calendar plate directly above it. This results in the alarm not functioning as it should. However, when I leave the screw loose, everything works perfectly and alarm bolt yoke is functional as should be. I've tried replacing the alarm bolt yoke, the alarm bolt yoke spring, and even the calendar plate itself, but unfortunately, none of these changes have made a difference. The only workaround I've found is to keep the screw on top of the alarm bolt yoke loose. Has anyone else experienced a similar issue or have any insights on what might be causing this? I'll also be sharing pictures to help illustrate the problem. Looking forward to your suggestions and advice! TT
    • Some news. After screws removal from donor movement, a family shot. From left to right: original (broken) screws new screws purchased from Cousins UK, as "Slava 2428 clamp screws", that didn't fit. They actually & definitively look too large screws removed from donor 2428 movement Here we go! First one is in position: Let's continue on the other side: Done! Next step will be putting back the hands. Another discovery for me! I keep going ...
    • OK, I have been there many times and know several solutions. As I believe, the pinion (the part with the leaves ) is on the other side of the arbor, yes? If so, then there is easy way to solve the problem. You can grind from one side as shown on the drawing with dremel tool. This will allow to push out the broken drill bit easy from inside. Then You will be able to insert new pivot and then You can solder it in place and in the same time to fill the ground portion with solder. Of course, I mean solder for PCBs, but not the led free one - use led containing solder, the led free solder which is offered in common hardware stores is for idiots.
