In search of... help!

Hi friends, I am an amateur so am turning to the experts for a helping hand...

I’m searching for a special gift for a milestone for someone who is an avid vintage watch collector. I think I am looking for a 50s to 70s De Ville. I was hoping to find a square, grey dial. I think these are quite are on the rarer side and are a bit more difficult to come across? As mentioned, I’m an amateur (that’s even being generous) and am not even sure where to begin. I’m hoping someone would be willing to point me in the right direction, or even be kind enough to pass along some words of wisdom!

Any help would be greatly appreciated 😀

You’re right, thank you! Here is a picture of something along the lines of what I am initially thinking. And probably the silver, however open based on what I’m able to find! Ideally, all original...
