Old Helvetia watch 1930? Not work


Recommended Posts

Hi and welcome to the forum.  The watch as clock boy Said is needing some major repairs. That is to say it’s not impossible for it to be done, dismantle clean and oil  new balance and spring, also mainspring and other associated parts, probably costly and time consuming and probably not cost effective. But depending on your skill levels and patience do able but at a cost.

good day, after a long search I found a watch of a very similar caliber, mine is 81-24, the donor's watch is cal. 81-26, we'll see how it turns out. I have a question, the hands have partially fallen off the ilum layer of the radio, what would you do to leave it in the original condition? or remove the rest from the handles? or covered with a new luminous. color? thanks for the opinions...

Though Helvetia 81-24 has center second and the 81 is subsecond, balance completes should interchange, the two staff s might vary a bit in height and pivot diameter.

Will you show a picture of 81-24 ?   lets see if its of the same grade as the 81. 

Whatever , 81-24  and 81-26.

That looks like a LOT of radium on the dial !  Take the necessary precautions.

    • Hello,  I'll do the cleaning and some assembly today. Hopefully, I'll upload some pics later today.  I have two questions: 1. lubrication of the "driving gear assembly for ratchet wheel"  The manual only prescribes lubricating the clicks and the pinion with grease (and the pivots of course): But this guy also lubricates another point (https://youtu.be/LmHqj5RMXqk?si=Mg5D7U0DEt_xf_MK)    What do you think?    2. Cleaning and lubrication of rotor ball bearings. From the service guide: a. Would you follow this cleaning approach instead of my usual L&R No111 (ammoniates watch cleaning solution) and L&R No3 (watch rinsing solution, two cycles)?  b. Would you use Moebius 941 for the balls?? First time I see this in a manual? Normally, I'd either use 9010 or Lubeta V106. What do you think? 
    • I've been working on an AS 1187, recently cleaned and lubricated it but no matter what I do, the rate is too high. In the attached photos the movement has the mainspring it came with, and it's older, but I have gotten similar results on the timegrapher when I put in a newer mainspring I got from Otto Frei, MS -711K. Here's what I've done thus far to no avail: After cleaning the entire movement I cleaned the balance assembly in One-Dip  End shake seems pretty good from what I can tell, but I'm not very experienced at making those determinations Banking pins look fine Checked where hairspring is running between the boot and curb pin. Seems fine. Curb pin seems fine (straight) Inspected all jewels on bridges, pallet fork, etc. All look good. What else should I do? Thanks!
    • Its based on Seiko 7001,   go on to    alldatasheet.com .  I think its a combined set mech. You likely to have knock the set lever out of whack. Rgds
