Rotary Movement Help ?

Recommended Posts

Hi All, Just after a bit of advice on a new find this week. Its a Rotary 1971 from the hallmarks on the gold case. Been trying to identify the movement on Ranft and trying to find a similar example but I'm struggling. Its a non runner at the moment so I'll need to strip it down so it would be useful to know what the movement is and if there is any reference material i can use. I've attached some pics if anyone can help or point me in the righat direction. Many Thanks.

I can tell from the distinctive auto-mind mechanism that this is an A.Schild (AS) movement.

Probably something from this family: http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&AS_1983

Look under the balance wheel more closely and you should see an AS symbol. Can you also see a number?

Where would I get replacement screws for the movement, there are three I spotted highlighted in the attached pic, Ratchet wheel and  two case screws. Noticed Cousins have a selection, do you think they would do the job? Or should I be ordering specific screws etc..

I think I've located the missing Ratchet Wheel Screw in the movement stopping it working. Thanks again.

Thanks, I need to look closer in future, thanks for your help.

Just to update the group, I retrieved the ratchet wheel screw and got it ticking. I can set the time but the winder stem is very stiff and I cant set the date which I belive is done by pulling the crown half out. I'll have to do a bit more work and remove and clean the stem etc. but thanks for the help so far.

    • that band is old as stated, there is a kit that pops up from time to time on selling sites for the repair of these type bands, some of this type are adjustable on a few links, one adjustable type allows you to align the round opening in the expansion slit [like yours] with the rivet to separate, but if yours won't come out then the rivet head is too big and will have to be done with some rivet removal and replacement, I suppose if you could make/optain the correct rivets that one could alter the said band, the tops/caps do lift off after raising the tabs....  
    • This is a watch from a friend who sent it to a neighborhood watchmaker for a battery change. It came back with the watch stem in a ziplock bag and the dial skewed 20°. The watchmaker told him that the stem was faulty and the watch cannot be repaired. I opened up the watch and found that one dial foot was broken off and still stuck in the movement, while the other was bent until it was flat against the dial. The stem could be inserted but it couldn't be pulled out to quickset and time adjusting positions. I did a full disassemble, cleaned and oiled the movement. But when it put in the battery, the second hand runs super fast. Like it gains 30 mins every hour. Any advice on fixing this problem? TIA.
    • I determined that the balance staff is rotating, not the roller table, so my second attempt at riveting was unsuccessful. I have ordered a new balance staff and will take measurements when it arrives. The balance staff i originally ordered (and now reordered) was specified as: Replacement balance staff: (A. Schild Caliber 984 1002 1021 1124 Original Balance Staff Part 723) so it should be correct. Measurements: (see pic below for terminology) xxxyy is a place holder until the new balance staff arrives. Lower pivot: Old - .08 mm New - xxxyy Lower pivot to balance seat: Old - 1.53 mm New - xxxyy Roller shoulder: Old - .42 mm New - xxxyy Hub: Old - xxxyy New - xxxyy Balance shoulder: Old - .86 mm New - xxxyy Collet shoulder: Old - .56 mm New - xxxyy Upper pivot: Old - broken New - xxxyy
    • Hello and welcome from Leeds.  We're here to help. 
    • I was just about to adk that, probably they have unnecessary waiting lists to make their watches appear more exclusive than they actually are.
