Just purchased a new Miyota 6M02 for a Citizen replacement. Day and date both set correctly using the stem in the first click position. The day and date do not advance when rotating the hands through 24 hours using the stem in the second click position. I've never encountered this before in all my years of replacing movements. Is there some trick peculiar to this movement that I am missing?

Does the calendar wheel rotate with the day and date finger on when you turn the crown in second position? You will have to remove day disc to see this.

It is a new movement and I do not want to tear it down to check that. I will probably return it and get another. I have just never seen this behavior in a new unit. I wonder if it was returned before and put back on the shelf. This is a common problem that surfaces as the calendar parts wear out. Very inexpensive (cheap) plastic.

Thanks for the thought.

      This eBay listing seems to verify that the watch disassembles as I suggested : here. The display caseback is held by the section that pushes out of the outermost rear bezel.  The movement seems to be a Ronda 1113. Best Regards, Mark

      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.

      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.
