Split winding stem - service tip.

Whilst doing lots of work on a one piece case Omega Dynamic my frustration mounted having to wind and set the hands with the movement out of the case. The split stem leaves just the male stub to deal with and the matching female crown doesn't always want to slip on. Also clicking it on is difficult - it's a hard push and holding the movement is awkward when out the case.

If you have the Etachron balance regulator adjusting tool it's a good fit on the male stem stub and will allow you to wind and adjust the hand settings with accuracy and ease. Just use fine pliers to pull out the stem for hand movements.

I will have to try that.  What I usually do is grab one of my stem extenders (I have female-end and male-end both)  and I put it in a pin vise.  I find it easier to use than the crown when a movement is out of a case.  I thought about using a piece of brass tube to slide down over where they join to keep them together while I turn them.

I have an Esslinger stem extender kit and just tried that but I didn't have any sizes that were big enough to fit over the movement side of the stem. I guess they must come in bigger sizes.

      I take it that you're comment re the Unicorn is 'tongue-in-cheek'? Would any of the watches that are on the link I posted be likely to be radium watches? What period was that prevalent in and when did the practice stop?

      As much as I hate Facebook, can a forum-like place be set up on there? Free and the ownership can be taken over by the next person whenever.

      Mechatronics Engineering v Mechanical Engineering

      By HectorLooi · Posted

      I existed before the term mechatronics engineer existed. I had to combine electricity, electronics, pneumatics, hydraulics and computing just to keep my own equipment working. I have never sub contracted any of my own repairs to the suppliers because I know I could do a better job. For a long time, dental suppliers in my country would bring their dead equipment to me that their own engineers cannot handle. I have accidentally embarrassed a couple of hospital heads of engineering by demonstrating their inadequacy.  I think mechatronics is the most under-appreciated, under valued of all the engineering sciences. I had a part-time dental assistant about 25 years ago, who was studying mechatronics in the polytechnic. She was absolutely clueless about the job prospects for a mechatronics engineer. I asked her about her aspirations and she replied that she really wanted to work in the games industry.  In our dental profession, equipment have evolved from simple mechanical to electro-mechanical to logic-driven electro-mechanical and currently to computer driven machines.  The medical equipment suppliers who employ mechanical engineers and/or mechanical engineers cannot cope with the repairs of the newer equipment. And many times end up changing whole modules and whole machines just because they cannot repair them. But I think HR is afraid to employ a mechatronics engineer just because they don't know what a mechatronics engineer does. Mechatronics is much more fun. It combines almost all of the engineering sciences and produces an all-rounded engineer. But until HR changes their mindset, not all door will be open.
