Can anyone tell me more about this dial? 1971 Perpetual 1002...

[bluedevil]

I have been scouring available resources looking for more information about the dial on my 1971 perpetual 1002. I cannot find any reference to the angular pattern on the face which is made up of thousands of small lines and rectangles of varying deep blue shades. My father gave it to me some time ago and indicated some degree of uniqueness. I love the watch and get a fair number of compliments on the beauty of the dial. Simply wondering how common or rare this is, especially since I have found just one photo online among thousands that clearly shows the same pattern. (And for you aficionados, please excuse the scratches, etc. - I wear it daily and it needs to be serviced!)

Thanks for any insight anyone can provide.

Dials like the one you have are rare to find (there is an Air king with the same dial posted a few days ago by Eye4detail). I have seen them not only in blue but silver in different models like ref. 1500 date. They are usually known as Textured or linen dials.

I have seen quite a few Oyster Perptetuals, Datejusts, etc. with unusual "unique" dials like yours, so this isnt odd. Dial looks original, very cool and unique pattern. As the OP mentioned, these pattern/textures are most commonly seen on silver dials of the 1970' and 80's.

Thanks folks. Yes, the dial is original. Even though the guy at the RSC asked me 10 years ago if I wanted a new dial since mine is slightly worn. Seriously?!?

Anyone know if the relative uniqueness adds to desirability/value of the watch? I'm having it appraised shortly for insurance purposes and trying to learn as much as possible beforehand. Thanks again!
