Hello. I was changing nh36 movement from one case to another, and quickset day/date change stop working. On second position stem is moving freely without engaging day/date wheels. Tried with another stem, same thing. Opened the watch and realize that the problem is somewhere where is shown on picture. What can I do?

Tear down the keyless works, and see what's out of place. Reassemble correctly.

I don't know about the NH36 movement (I don't think it's one of them, but I've never pulled one out without tearing it all the way down), but some movements are designed such that the crown must be in some position or another before you remove it lest you find yourself in this exact situation.

Welcome to WRT forum.

If the picture was clea,r someone might see what part in the keyless has jumped out of place.

Have you googled for NH36 datasheet?

Yes, but I'm not sure if it's the keyless because small wheels engage but they don't have enough power to change the date. Looks like something is out of place or it's broken.

 Whatever the fault is, a clear close up of the keyless helps spot it.

I've opened the watch once again. Keyless seems good, not broken teeth. Everything is in place, but there is no power to turn the date wheel. Seems like there is a weak spot somewhere.

I've uploaded two videos on YouTube.

Sorry for bad focus.

      Hello everyone from Idaho. I started up the hobby about two years ago and love it. My latest repair, that I'm very proud of, is an Oris big crown pointer date 7400B. I'm excited to learn and to help out where I can.

      An update... I bought some 316 steel washers from McMaster Carr. For days I have been turning it to get to what you see in the image.  it is not done, of course.  the inside diameter of the top as shown is close. The washer is too thick, so I am gonna need to figure a way to make it thinner. Last week I had a long talk on the phone with @SwissSeiko and got some tips. He suggested Harbor Freight insertable carbide cutters. Wow, they work well. Miles to go before I sleep. Here is my setup

      Plastic gasket for Citizen case back.

      By Kab · Posted

      Hello all.  I've been working on a Citizen H145-S073545 radio controlled. There was a plastic gasket in between the case and case back. Putting it back together I used a press, witch I think was a mistake, because it cut the gasket open. I've been looking online for a replacement but not having much luck. I've tried a couple crysta gaskets but that didn't work.  Any ideas of where to find these gaskets? Thanks all.

      Loose pinion

      By mbwatch · Posted

      Yes I think blue thread locker would help you out here. You will lose the safety mechanism if the mainspring snaps, which risks damage to train wheel teeth. But your watch might run. You can maybe try inserting a hair inside the pinion and threading it on. That might give it just enough to grab hold without thread locker. Or a tiny piece of superfine copper wire, a strand from some stranded electronics wire.
