What can be the cause? Age? Any insights will be appreciated. Thanks.

 

I think age indeed. There is also no Tritium in the hands anymore and the color is the same as the left subdial hand.. they look legit to me

 

Mine look somewhat like that as well it ages.

 

Thanks for looking!

Thanks for checking

 

Is this the one currently on eBay?

 

here's mine in a previous post : https://omegaforums.net/threads/in-search-for-a-dial-flat-jedi.27425/#post-965398

 

yes

 

Likely UV, the original paint/finish, moisture, and the degrading tritium combined... it's pretty common to see orange hands on Omegas turn shades of yellow (flightmaster, Jedi, Speedmaster MKII...)

 

sun bleaching
