Okay - primary mission accomplished, and to be continued. And no - the Super-LumiNova coating on the hands is not radioactive. Enjoy!

    As it’s just a tiny bit out use the force from the stepper to ‘nudge’ it. Without a tool you can also pick it up with tweezers. Stay central and it will pop off 😊

    Horologists would be horrified! ⏱️

    I really enjoyed this video. Thanks.

    Wish I knew about those watch presses six months ago. I shattered a watch face changing the battery because I had the same issue getting the back closed up. Fortunately it was a cheap watch from Target, not one of my good ones. I will definitely be investing in one before I think about touching my good Bulovas. 😅

    Sounds like you’re putting your expertise in handling delicate equipment to work! Awesome!

    Steinhart makes an inexpensive mechanical automatic ( valjioux 7750) aviation watch like you got there for under 1000.00. But it has a really low water resistance rating like 3 atm which means no swimming with it no shower or bath. For alittle more….LIV watches make a nice aviation automatic ( valjioux 7750) for 1500.00 .

    A quartz watch, shame on you!!!! Automatic is the only way to go, you should ashamed of yourself !!

    My Casio solar watch has a function where I can realign the minute hand. It also calibrates the analog watch with the digital display. Strong vibration or strong magnets can affect the function of the minute hand, which ticks every 20 seconds.

    It's awesome to have a watch that never needed the battery replaced. I had this watch for ten or more years now still running on the original rechargeable battery.

    Your so clever & smart

    These ETA movements that Tissot use are nice but when the second hand consistently misses the mark like that a hand reset is what you need. Or, rotate the dial 3 degrees 😀 But they have mechanical innards too that need lubrication just like mechanical watches and they disassemble quite easily. What they don't do is assemble easily. I have one one my bench right now and I need to order titanium tweezers as the servos are magnetic and normal tweezers are steel 🙂

    One last thing Fran, please use finger cots or nitrile gloves when handling watch insides – finger prints cause corrosion and staining that never comes off, especially on the dial (which cannot be cleaned)

    When you first pulled out that press I thought you were going to say it was a letter embosser that you'd repurposed.

    The second hand moving between the hash marks seems like it makes it easier to see.

  14. Avataaar/Circle Created with python_avatars Franklin Tabor says:

    From a human user interface perspective, prioritizing contrast, wouldn't one want the second hand to stop slightly offset of the second markings?

  15. Avataaar/Circle Created with python_avatars vonkruel says:

    To remove hands you can get by with a cheap "presto tool" (use plastic to protect the dial). To place the hands you can find cheap handheld tools to assist (magnification will help when placing the second hand!). I don't know what tools you already have, but a cheap "watchmaker's starter kit" could be a good option (including a spring bar tool, case opening tools, bracelet sizing tools, hand removal & installation tools, etc.) The included tools may not be of the highest quality available, but unless you find a much crappier kit than I did, they will serve you. Anyway it's a cool watch IMO and I like Tissot.

    good video, order the tool to get it working like you want or take it to a repair shop

    I wouldn't work on Tissot with anything less than a 1.5k ohm 1/8th watt resistor. ha ha hehe! good video Fran!

  18. Avataaar/Circle Created with python_avatars Simon Tay says:

    Why can't you just use your finger nails to pull off the second hand. Turn both hands so your palms are facing up and hook the nails of your index or middle fingers under the second hand and contract your fingers (makes a W) to pull it up. I use my finger nails as tools for lots of things.
