Second hand randomly stops

Hi folks,

I watched the WR Channel and decided to regulate my NH35 with a very minor push on the lever with a wooden toothpick. I was very careful and I’m confident that I have not touched anything else. 
 

the second hand now stops randomly(no certain position). I tap the watch and it picks up again but then stops a few seconds later. I have hand wound and now wearing it but it keeps stopping.

has anyone experienced this before?

Look like the small push indeed produced different results from the intended one.

Was this the first time you went hands on to a mechanical watch? 

Since I assume you have no timegrapher or equivalent application (these are practically mandatory to properly regulate a watch) the only safe step you can take is to post some high quality picture of the hairspring stopped, and high quality video of it running. A good audio would also help others help you.

I think I worked it out, I pushed the lever back and it’s now running fast again but second hand is not hanging up anymore.

yes I’m waiting for a time graphed to arrive.

thank you for taking the time to reply

To give you an idea of the amount of movement needed to correct an error of 1 minute a day, it’s so small that you can't tell by looking at the pointer, and just slightly feel it while pushing. And for that a toopick is not a good choice because is too small and flexible to transmit the feedback to your hand.

      Etachron regulation system

      By BobG · Posted

      I’ve been playing with a NH35 movement that which has the classic Etachron regulation system and a few balance assemblies as practice. What I’m trying to do is get comfortable with the effect both the stud and regulator pin positions have on rate and positional error. When I install a new balance assembly I install it with the assembly in place  on the cock and cock is attached to base plate. I use the back of the tweezers to push the stud into place and feel the click. However, I noticed that the angle of the stud can be adjusted and what I also noticed is that some movements have the stud carrier arm bent down a little and that changes the angle of the hairspring leaving the stud. This angle effects how the spring goes through the regulator pins and also the spacing of the coils opposite the stud. What I thought I was supposed to do is set the regulator block in the middle of the curve, open the pins, and use the stud angle to center the spring.  Then the stud is set.  Now on all the new NH movements I have seen the angle of the regulator block is about 60 degrees counter clockwise from full open. I watched a video where the author used the regulator pin adjust to adjust rate and position error. When I close down the pins I do notice that the rate increases but also the amplitude drops, the coil spacing changes and hairspring appears slight straighter between the stud and the regulator block. If I open the pins the amplitude comes back, the spring breathes a bit more between the stud and the regulator block and the rate slows.  So, a long post I know but I would really appreciate any advice on how to correctly adjust the etachron system for rate, amplitude and positional error.

      Aw come on Andy, it was just a comparison between spending 30 quid and tackling a tricky piece of work. You appeared to be volunteering,  i volunteer for stuff all the time it gets me into all kinds of trouble.

      Tissot case back removal

      By Neverenoughwatches · Posted

      It's not really shown here , but the blade flips over, so it faces the other way. The knob and threaded case holder then pushes the caseback seam into the blade. Once the blade starts to penetrate into it, the lever and blade are lifted , which should hopefully pop the back off. A lot of fashion style cases have very tight seams and need a sharp blade to start separating them.  Don't buy the cheaper plastic versions of this tool, the posts with the pins through for blade holder break easily if the apply extra force to blade.

      You will still be looking for a balance complete I’m afraid, this is the balance staff, balance wheel and hairspring in one package. Hairspring and the balance wheel are matched in the factory. Whilst we can change a balance staff the hairspring and balance wheel stay together.   Tom
