I was scrolling through this site over lunch halfway looking for a desk fidget toy for my toddler so she doesn't try to grab things she shouldn't when we're "working". I stumbled on this. Miyota 8215, sapphire crystal, stainless case (if you get the silver one)... Pretty decent. One thing caught my eye though that gave me some serious pause/raised questions that are not answered. See if you can spot it.

Continued scrolling and found this one:

Actual ETA movement. "Hard difficulty" seems to mean a small seconds hand, and it looks like maybe they removed the ratchet wheel and click? Still, same pause/questions as the "medium difficulty" version.

Exactly what I wanted to know!

It also took me a second on those giant pliers, but I think they're most likely for cutting the stem. After a few hours of it rattling around in the back of my head, I'm thinking the superglue MIGHT be to glue the crown on the stem...? Best guess. Next best guess is that they only have a single size screwdriver in the kit, and dial retention screws tend to be itty bitty... Might be the glue is to hold the dial on? That would be awful, but that was my knee jerk reaction owing to a recent experience. Hands and spring bars loose in that little plastic container seems a bit iffy as well, but maybe that's not actually how they're shipped...? 

The "Hard difficulty" version is cheaper than the "Medium difficulty" version, and comes with a 17 jewel ETA instead of a 21 jewel Miyota. I would have expected the ETA to be more expensive, but admittedly it's too difficult for me to buy ETA parts anyway, so I don't keep a thumb on that pulse. I don't think I ever came across an "Easy difficulty" version. I'm not completely sure what it is about the "Hard" version that's more challenging than the "Medium" one. The small second hand pivot can be pretty fragile maybe. Surely the ratchet wheel/click being removed isn't what they're intimating is more difficult though. I'm not sure what other differences there are between the two kits from an assembly perspective. Installing that would be much easier than... installing hands? I don't know. None of the activities involved in assembling either kit register as part of a service; just stuff you do when you're all done to sort of clean up before moving onto the next thing...

      Intro

      The Boro has changed quite a lot over the last 20 years, and not for the better. I actually moved out of the town 15 years ago to a small village not far away. Thanks for the pdf! Looks a great read. I'll get it printed today and put it on my work bench!

      New balance staff not riveting to balance

      By Endeavor · Posted

      Not having all the fancy equipment, this is a way I came up with. I never said it was the best, the most ideal or the safest way. Working on balances is always a delicate task and full concentration & common sense should prevail. I was well aware of the "dangers" / short comings involved, hence my "warnings", as quoted above. The balance wheel of the Omega was nice true, flat and one could clearly see how much gap there was left before the grinding wheel would touch the balance wheel. My idea of penning this article was to show/share a way which, in my case, perfectly succeeded. If deemed to risky, or if the balance wheel is not true or has a wobble, other methods have to be followed.

      Seiko 6601 Tech Sheet?

      I loved his explanation of a teardown 😅 Ex military Richard Perrett, pretty knowledgeable guy.

      I also see a bit of danger for the wheel, at least you have to keep away from it and may get a too thick rest ring. My rest rings are about 0.05 mm. Better way would be a grinding wheel touching the staff with its circumference. Frank

      Stem broken - can it be rescued?

      By Neverenoughwatches · Posted

      Not easy to find this one everywhere,  so it depends where you are located. Joining it back together might be possible, i have silver soldered mild steel before even with traditional plumbers lead and its a pretty strong joint, but bere in mind this is only 1mm diameter.  The join would need to be very accurate,  it not something i have heard of anyone trying before. The part no 401 is the swiss code number and relates to watch winding stems in general
