Patek with a restoration dial - Are they still desirable?

[arejay]

While browsing around my local market, I came across a Patek Calatrava from the mid-late 1940s. Upon talking to the dealer, he indicated that patek replaced/restored the dial sometime around the 60s. I guess and extract from the archive would confirm that.

Generally, I prefer all original, but I've never come across a Patek restored/replaced dial before. If it was anyone else doing the restoration I would be hesitant. It certainly isn't shined and new looking. Still has 50 years of age on it.

Does an actual Patek restoration affect the value or desirability from collectors?
