Watch Hand Alignment (Mechanical vs Quartz)


Recommended Posts

Hello all, hope you're well.

I've been working on Miyota movements for years and usually if the movement doesn't have a calendar i'll move the hour hand backwards to twelve before installing the minute hand.  I got told this before but I've never fully understood why.... can anyone clear that up for me?

As opposed to any calendar or quartz movement that i'll always install with the hour hand adjusted forwards to twelve.

Thanks for your time and patience

I've had to repair quartz watches (needed the money) and as I understand the mechanism, with a basic hour-minute-second SMQ it has no mainspring or any other works to offer resistance that would damage the train, so it won't matter which way you turn to set it.  But I am in the habit of setting clockwise because it is safest if you do not know the watch well.

With additional complications such as calendar functions, those are meant to revolve a certain way and you are correct to only set them in a clockwise direction.

It's mostly always installing from new, and the Miyota movements I refer to are all mechanical by the way (82S0, 8N24 etc).

I believe it is something to do with when the gear train re-engages after changing the from time setting mode.  Thanks for your replies, great community on here!👍

    • I'll go halves with them John , we can share it 😉
    • Besides locktite Nev, is there anything random that you use to fix in the pivot ?
    • Thanks Hector, I do think though that the problem I am experiencing is specific to Miyota movement in general and the 6T series in particular.  When you describe putting the bridge you are talking about the train wheels.  The problem here is that under that same bridge you have the 4 train wheel, the barrel, 2 extra winding related wheels and the center sweep pinion.  I can mostly put them in their holes but 2 of those (the 4th wheel and the second pinion are completely under the plate so I can't nudge them in the right position.   I managed it with a larger Miyota 8200 series but with the smaller 6T15 it is even worse. Anyway, I'll retry tomorrow evening or this week end.  This evening is going another rock climbing day (going from very light pressure on tweezers to much more force going through the fingers, although in climbing we also want to use the absolute minimum grip which won't make us fall to save the muscle and be able to climb longer routes). to add insults to injury, if you read this thread from the start, I initially messed up the disassembly as I couldn't detach the rotor.  I normally (and I think I did this time too) put all my parts in their individual compartments in the part tray and I am doing my best to be very careful about them.  But in the week and a half it took to figure out how to detach the rotor I somehow lost the screws from the bridge.  I have a few others which will be needed later.  I know they are reference 922-600 but I couldn't find what it means in general term so I don't know if I can buy replacements or an assortment of screws and replace those 2 by others.
    • Something that can happen with a lyre spring, the back of the arms can bind against the shoulders of the chaton cut out where the spring is fixed in when the spring is lifted out of the way. To stop the spring bending or breaking it needs pulling forward slightly before lifting so it clears the edge of the chaton.
    • One way is to file it by hand. Good file with sharp edge is needed. Another way is with the aid of milling attachment. There is one more way, thyat is really only on the lathe, but the arbor has to be attached perpendicular to the axis of the spindle. Will be easier to show pictures than to explain this. I must say 'Good night' as my wife is now awake and is roaring when I get closer to the computer...
