Hi Guys   Has anybody heard of quartz movement  by TecnoTime   from information gathered they are/were France Ebauches movements, although the movement has swissmade and case back made in France. The movement is marked with TT in a six sided lozenge. Problem is it is duff, and will probably need replacing. Should that be so has any body got any repair info on these movements and what would be an equivalent unit to fit if the origionals are not available. My thought was possibly a ronda unit somewhat like the 1064.  I have yet to investigate the cause of its demise and I'am exploring possibilities.     Thanks.

Hi Stuart    I have further investigated this watch (Technotime) and they are indeed FE  France Eubauches movements The one in question is  a FE51200 or FE5120 as designated they are now obsolete and the replacement unit is a harley ronda HR751 but the dial feet positions differ which means moving the feet or using dial dots. although I have found one in America so await orders as to what to do, which way to go.   They look good units very much like the ronda. I have found all the relavant technical information on these now.    Thanks for the info Stuart,    much appreciated.

    • Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.
    • I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.
    • Get well soon Old Hippy, torn muscles.,  not good
    • Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.
    • If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
