5140 vs 3940 Dial Dimensions

[qwerty123]

Good afternoon,

I have been looking more and more at perpetual calendars Pateks, and I am considering going for either a 3940P or 5140P and I was wondering if a 3940 dial could be fitted to a 5140, considering the case dimensions are very similar.

I much prefer the dimensions and exhibition caseback of the 5140, however, I am not a fan at all of the font and font size used.

Thank you!

Not sure on dimensions but would be interested to follow along in your journey. I have been looking for a 3940G or 3940P for months.

I have reservations about this type of modification but…

the saatchi limited release was a 3940 case with a 5140 salmon dial.

Can’t say if they modified either or simply made one look like the other?
