as far as I know they were always there sort of. In other words there they are to tilt the fork to be in alignment with the coil. The problem is they're not always the same as the image below shows there in different colors. Although I don't think I've ever seen a black washer usually the gold is the most common or the copper color occasionally. I am assuming there was a manufacturing tolerance with probably the tuning fork to get a line with the coil assembly.

So basically anytime you have the washers when I take the fork out I put the screws back in the keep the washers where there supposed to be that way I don't have to worry about mixing them up of two different colors.

If the watch has been worked on by somebody in the past, we cannot assume that the washers are in the correct positions. The test is the fork must be properly centred in the coil formers and the index finger is in the same plane as the index wheel.

      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.

      Pcket watch "Art déco"?

      I can't find anything similar either.  All the writing on the case was a form of advertising, stem set, Swiss lever etc usually found on older watches.
