1947 Rolex Precision 5520 would like info??

[jet512]

I have a Rolex 5020 precision in Stainless and Rose gold (RG engine turned bezel) with the original ss/RG band with the rivets on the sides in super Excellent condition. I also have the original presentation box which considering the age is in near mint condition. I had the watch and band rebuilt last year by my Rolex repair man. Except for the fact that this is a vintage piece it basically looks new with patina on the face. The watch was my father's who purchased it new. The serial number is 626446 which dates it to 1947. The watch is a mid size about 33.5mm. Any idea of the rarity or value of this piece. I have a Daytona and this watch is much too small for me. Thank you for any help.
