Installing Watch Hands

Recommended Posts

I just completed a complete clean and rebuild of a Seiko 7548 Diver and have a question regarding installation of the watch hands. I turned the stem until the date flipped so I would have an actuate 12 O'clock position. Then I installed the hour hand without issue. Upon installing the minute hand I noticed that I can end up in many positions. Nose down, tilted, etc. Is this normal? The second hand is also no issue as it feed over the pivot. I did manage to line the second hand up parallel but it seems like and violent movement and it will be tilted again and the other hands will touch. HELP!41b0a3ad84fa5600b9dc0e08026bf640.jpg

Don't overthink it. First I suggest after installing hour hand advance at 6 to install minute, and check alignment at the various hours, and date advance again.

Then just check that the top of the hand is flush with its pinion that should give the correct distance already.

Chek the hand is not tilted, correct as necessary it should be good to go.

Maybe you just need to reduce the hole in the minute hand. I insert a pin or something with the approximate diameter of the hole and squeeze the outside, gently with a blunt nail clip I've prepared for this   (I filed an indentation in the middle, easy to make). The idea is not to collapse the hole or making it too tight that you can not insert the hand.

thanks Bob, great idea in fact.

so, what you guys use to install watch hands? I suppose you dont use any helpers like staking set or hands press. Problem here might be that hand is not pressed evenly so it tilt. When pushed perpendicular it should install correctly, doing it by hand its easy to tilt it. Im not trying to say you have to use helpers, only that it has to be pushed evenly. Just try if you have access to stacking set or press and you will see the difference. Since I started using my stacking set for this, for balance jewels (I only do South Bend watches) it is much better, but I think you dont have to use it, just get more practice and know what could cause problems  :thumbsu: .

So did you mean that you turn the dial so that the hour hand advances to 6 and then install the minute hand pointing at the 12 o'clock position ?

    • I’ve tried everything using both my blue and donut demag units.  I’ve even tried beating them with a steel hammer 🙂   im now trying heating them over gas flame — if that doesn’t work …..
    • The 110v supply could be problem with the blue one. Have you tried moving the piece to demag through different orientations manually as its drawn away ? As Nev quoted the magnetic fields of the demag have to overcome those of the steel. 
    • Thank you Marc! I re ran the TG. First I went ahead and checked the balance jewel on the regulator and it was bone dry. I cleaned and oiled it, not without some drama including pinging the capstone and searching my bench with a black light for 30 minutes and finally shone it on my face and looked in the mirror only to find it on my left cheek in my 2 day growth! Back in and on the Grapher we are at 275. However significant drop in DD (234) and CR (190 edited) positions tells me it's time for a complete cleaning and oiling.
    • My $12 blue one seems to work well enough for movements out of case. However for  tools with greater mass, such as my small and large anvils which are highly magnetized the blue unit is useless.   For whatever reason, my high current K&D donut unit just doesn’t seem to work, regardless of my attempts to use it as instructed in this thread (magnetizes stuff fine so I know it is energized).  
    • PUW1563 is the day/date version of the 1561 (date only). I have just measured a 1561 using the old "blob of paint on the rim" technique to determine the actual amplitude by observation, and then putting it on my TG and adjusting the TG lift angle until the displayed amplitude matches the observed amplitude. I get 48°. Not a million miles away but it will have overstated the amplitude by about 20° with the TG set to 52° (I tried that as well for completeness). So with a more appropriate lift angle set on your TG you would have got an amplitude reading of about 240°.
