Okay...here is how you convert a 2836 GMT into a 2846 GMT and also disable the GMT quick-set function to make the GMT into a 24 hr movement, just like the gen...
Here is a pic of the spare 2836 GMT movement that I will be using...
You need to remove the following to do the conversion:
1. Was the intermediate date wheel, but is converted to the intermediate GMT wheel. This wheel is slaved to the GMT wheel.
2. Date jumper maintaining plate
3. GMT wheel assembly...to be on the safe side, I also removed the cannon pinion and the hour wheel
4. Day corrector, which has been converted to a GMT corrector. The quickset for the GMT function.
You should have all the parts below, including the jumper plate (no pic)
Notice the subtile diffferences of the jumper plate. You must ensure that you use the correct one in order for the plate to clear the intermediate wheel. The top one is the correct one to use. You will notice a pronounced notch is cut out for the intermediate wheel...
Here is the pic of the 2846 that I will be using for the conversion. Pay particular attention to the wheels that are currently in place...
Now to replace all the parts on on the 2846 with GMT parts...
I disabled the quickset function by not installing the GMT corrector. But I did keep the quickset function for the date, for convenience. If you want to disable the date function to make the movement even more accurate, then you would just need to remove the double corrector...it looks like a "star" wheel that is right next to the GMT corrector
Let see if it works...12 noon
...and 6:00 PM or 18:00hrs
...and with a silver date wheel!!!...where's alligoat when you need him???
