I don't think I can afford the 9010 for that.

Luckily it comes with a tiny candle to wax the relevant parts. I'm not sure if it's made of solid 9010 or what 😉

OK. You've piqued my interest. Tell us about the quality of the kit, please.

I have to say, overall I'm very impressed. The instructions were very good and easy to follow. Having a knowledge of how a Swiss lever escapement works definitely helped when putting together and tuning the tourbillon though.

Getting the mainspring in and wound properly took several tries, and was probably the most frustrating part.

Once it's all together, the parts do need to be lapped in. The instructions say to turn the tourbillon for 10 minutes by hand, but I found mine needed a lot more running time once it was assembled. You just have to wind it and keep giving the balance a nudge when it gets stuck on the pallet fork.

The real issue I had was with part of the tourbillon coming apart while running. I'm still not sure if it damaged anything, but I did use a little superglue on some of the more important parts when I rebuilt it.

It's far from a Swiss timepiece, but it does have beat and rate adjustments, and it really looks cool spinning around on my desk.

I found it on Amazon, and looked over the reviews. Clearly not a watchmakery crowd. One person said it would run for a few hours after it's been run in for a while, but most were stuck around 2 minutes or less (user error from the sound of it). How long does it run under competent hands?

I wish I knew, but under my hands it seems like a few hours is about right. There is a lot of friction in the system, and it doesn't seem like the mainspring has a ton of reserve.

But then I've never timed it, and it may change as it wears in.

90 minutes since winding so far, and it's still going strong. One thing I do notice is it runs very fast, even with the balance spring as long as I can make it. It's gained 10 minutes since winding it.

But again, I don't feel like it's meant to be a chronometer. It's a super cool desk toy.

Edit: stopped just over two hours. A nudge of the balance wheel got it going again, but it seems like the mainspring is running out of power.

So it's not a clock so much as a cool contraption.... Bummer... Seems like a lot of finessing could make it work well enough for what it is, but if it can't run for at least a day and change, it can't really be a clock per se.

      Battery

      Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.

      Stem removal after fitting hands

      By PeterS · Posted

      Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad

      A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

      Stem removal after fitting hands

      By Neverenoughwatches · Posted

      I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.

      Yes I understand that. What I’m asking is, after the hands have been fitted, it’s been checked that the hands do not touch etc. then I need to remove the stem to fit the movement in the case. I have the push type, I need to turn it upside down and push the setting lever post and pull the stem out. But of course the dial and hands are in place and I have a glossy dial with lume dots and I do not want to cause any damage while it’s upside down pushing on the post of the setting lever.
