Ahh didn't know the Yuki has adjustable end shake as per Rolex.

If it runs fine in some positions, it's not the roller jewel. Probable causes are, cracked shock jewel, bent balance staff pivot or shock jewels not installed correctly. Start with the upper and lower shock jewels. Remove them, rinse them in lighter fuel, renata essence or one dip etc. They should separate in to 2 pieces. Remove them from the fluid and place on tissue paper. Ensure the domed side of the cap (there is a flat and domed side) jewel is facing up, put your index finger on top of it and polish on the tissue paper. Now flip it over and inspect it with a loupe, it should be a like a mirror. Any imperfections and it's toast. Replace it. If it's ok, place a circle of Moebius 9010 in the centre, covering 2/3rds of the circumference. Now take the shock jewel and carefully place it on top of the cap jewel. Capillary action should suck the 2 halves together. If you smear it...Start again! Once you have done this, reinstall the shock jewels. see what the actions like then. If it's still no good, swap the shock jewel assembles on the top and bottom. Not sure about these but on some movements the cap jewels are different thickness. Once this has been done and you know the shock jewels are free from cracks and imperfections and cleaned and lubricated we can move on. Dial down carefully inspect the hairspring from the side (horizontal) whilst mounted in the movement. Ensure it is not touching or brushing anything during its rotation. Look really, really carefully. See if there's any noticeable wobble in the balance wheel. Let us know how you get on

Do you know if the watch is fully wound? If you movement.u wound the watch and then it stopped winding then it is fully wound and because the watch is not running it is not releasing the power to enable you to wind it again. If this is the case then it could be many reasons why the watch is not running and will need a experienced watchmaker to diagnose and repair the movement.

Is the watch running?

I can't work out what's longer, the minute hand on that 'thing' up there or the nose on the person trying to sell it as gen

I don't see anything wrong with your hairspring, the coils are concentric and in the round. Look at the hairspring from the side (horizontal) it should be absolutely flat. The only reason there would be a issue with the roller jewel is if it's been tampered with. If it hasn't leave it be. To diagnose problems with low amplitude, you have to start right at the beginning with the mainspring and barrel. Is it old? Has it been changed? Once you know the mainspring is supplying adequate power, you move to the gear train. You need to check it is running completely freely. Remove the hairspring and pallets (power removed!) apply a little power to the mainspring and watch the gear train, it should spin freely and when it reaches the end of the power from the mainspring, slightly reverse spin. Once this is ok, install the pallets and wind the watch a few turns. Now you check that the pallets are locking, unlocking and return to banking. To do this gently nudge the pallets, they should cleanly 'flick' to the opposite banking pin and hold tight against the banking pin. Now do it in the other direction and you should see the same. Now give a tiny nudge to the pallets, just enough for them to move a fraction from the banking pin & then be drawn back to the banking pin. Do this several times on both sides of the banking pins. If ok remove pallets (let power down first!) install balance assembly and gently rotate the movement dial up, dial down & dial vertical. the balance should rotate for 15-20 seconds before stopping (slightly less dial vertical) Once all these tests have been performed you can move onto dealing with hairspring problems & roller jewels If you diagnose a problem at any of these stages, let us know and we can work from there

In & out 8 times with Safari 10.0.2 All good

I had to replace a couple recently from a Tudor (ETA) damn expensive little wheels! VP105 is my goto lube for reversing wheels. I used to use RM's method of a fine oiler and 9010 but my hands aren't steady enough these days Nice write up 'G'

I love column wheel chronos, even the Chinese make a nice looking column wheel chrono. It's such a shame most of these V72 watches are butchered for their movements

He got the money, didn't he? The CC company refunded our guys.

The ETA movement in that watch is a F04.111 calibre. It is £15 to buy brand new. https://www.hswalsh.com/product/eta-f04111-quartz-watch-movement-mzetaf04111 Save your money, get the cheaper one. Ronda movements are great, I recently serviced (changed the battery ) in my brothers gen Tag Heuer F1. That has a Ronda movement.

You can certainly remove the calendar works and then probably modify the setting lever spring so that it has only one detent for time setting only.

Did your CC company recover the funds or pay out through insurance? Has the selller still got the money?

I recently serviced this (gen) for a customer. It is women's 'mid' size at 36mm. She is around 5' 2" and very petite, the watch looked perfect IMO. I wouldn't go for a Daytona like you have above, way too big. 36mm is a good, modern size women's watch

Interested in low beat chronometers.

I didn't as I didn't take much interest in it at that time. When we resume our training (Horology) after the holiday, I will get some better pictures. I hope it is OK, he's a nice guy but a little naive

The movement is a Tudor 390 (FEF 380) I helped him re-assemble it when he serviced it.

These 1 watt 445's are pretty long in the tooth these days, I was making my own pointers about 4-5 years back from these diodes harvested from Casio DLP projectors like this one... https://www.youtube.com/watch?v=gF4HG6v29UY 24 of them 1 watt 445's in that baby These days, 3.5 watt is doable from a single diode. Hobbyists like to mess around and combine 2 diodes for ~7watts I gave up on pointers and went the whole hog and built my own red/green/blue scanning projector doing graphics and beam shows using Pangolin software. Lasers still fascinate me

Anyone got a source for a replacement handset or where he should be looking/asking?

Cheers gents, The watch belongs to my friend. He contacted me for advice as he is considering getting the hands re-lumed and whoever he has contacted regarding that has recommended that he has the dial re-lumed at the same time. I just wasn't sure about the dial. The condition of the dial just doesn't seem in character with the rest of the watch? if you think the dials good then the sensible solution is indeed, replace the hands. cheers.

Any opinions on this? I get the feeling the dial is wrong rather than just an issue with the hands. Movement is gen and I think the case is too. I just don't know?

Errr....Where is the "to good to be true" sale gone? Did it go belly up?
