Orient GMT Cal. 40p50 or Cal 40p51 date disc change

[k3l3k]

Hi, Could someone kindly post a dial side picture (without the dial) of Orient GMT cal. 40p50 or Orient GMT cal. 40p51 (both with power reserve indicator) ?

I would like to change the date disc and would like to find out

1. The difficulty level for the swap.

2. Compatible date disc for the swap. My current date disc seems to have developed some kind of crack on the tooth (so not moving).

(I am not a watchmaker)

Hi  Found nothing regarding the 40p50 but some tech sheets on the following site might be useful        https://www.watchuseek.com/showthread.php?t=256011

Surely too high for someone that has never worked on a watch before. You may get into trouble way before you even get close to the part that bothers you, as in removing or refitting hands or dial. Some specific tools are also needed.

Orient is known to not distribute or care about spare parts. Without measuring the date ring precisely is impossible to even start looking for a replacement.

In any case without inspecting the complete calendar works one can't tell if the date ring is the only defective part, or if it perhaps could be repaired.

Here is a picture of what I requested (from this link) for anyone else who may be looking for it. 

Would someone help me with the part-number of the Orient date-disc (the one on mine has a broken tooth)?
