Replacment Crown For Tag

Question

I have had a very hard time locating a replacement Crown for this TAG AQUARACER (REF. CAF1112) I am fine with a generic so if any one has a suggestion. I have seen some companies here in the states offering replacements but they are asking for dimensions and none of the offerings seem to match  what I need.

 

The crown measures 6.00 mm diameter by 4.6 mm tall. The stem measures .8mm (Tap 11) but all of the replacements are for TAP10's. Any suggestions would be greatly valued.

There are two tap systems. In the uk 0.9mm = tap 9 and so on. The American system goes in the opposite direction from what I have seen. So 0.9mm is tap 10 and 0.8mm is tap 11. I would guess that the stem for a large chrono movement would be 0.9mm rather than 0.8mm. Can you check the calibre of the movement? Other options are to use a tap 8 to tap 9 stem extender or some glue ( last resort ) as the tap size is only one size out. With screw crowns the thread is usually much more difficult to match than the tap.

    • Good to be here, found this place while trying to find out what or where I was going wrong with a Seiko 6119 movement,  just wondering how come i have never seen it before.  I am Francis married with 3  children, all under 10, yes I started late since I am 55 and wifey is 33.  Started off doing pocket watches and somehow now getting into Wristwatches.  Still trying to work that one out. Bought a lot of movements some 10yrs ago and have had them stored away, and now we decided to put down roots, i dragged it all out and now trying to learn more and more as I go along.  Francis Downunder.

    • The stem looks like thread worn at top, but might be just the angle of picture. As for the hands not turning, possibly something has slipped on mechanism, like a spring. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Longines_23ZS might be worth comparing the picture with yours. 
    • hi I'm working on a longines .caliber 23zs. It was not working and i noticed if you moved it the balance would start and the hands revolved until the second hand reached number 5 where it was catching. To cut a long story short i have removed the hands and refitted them and there going fine. But when i went to reset the hands nothing. I pulled he crown out to the position to move the hour and minute hands and there nothing happening. it turns freely but the hands don't.The crown has now come off as well but that screws back on though it seems loose. I have cleaned the stem and examined it to the best of my knowledge and it seems fine. It slides in and out when i release the screw holding it into the movement. I have tried to download docs from cousins but they only show dial diameter.  I have also googled it but there's not a lot out there.Not what i need anyway. I'm just wondering have i missed something obvious that should have been done.. Any advice gratefully accepted. cheers gary
    • if you have a tap and die set,   (and a lathe) just thread a hole in a brass rod and you have the perfect "screw holder".    doe's not work on left handed thread.    vin
