Hi there
I am Pretty sure that your watch is a genuine Patek Philippe, Ref. 1413 from the 1940s. There were several variations (steel, steel and yellow gold, yellow gold and rose gold). Yours seems to be the rose gold and thus the prettiest of them all - in my humble opinion.
Quite a find you made there.
| Patek Philippe & Cie, Genève, Ref. 1413, 1940's. Very fine, 18ct gold gentleman's wristwatch. |

C. massive, polished, teardrop lugs. D. with applied gold indexes and Arabic numerals + auxiliary seconds dial. "Bâton" gold hands. M. 10"'-105 rhodiumed, "fausses côtes" decoration, 18 jewels, lever escapement, cut bimetallic balance, flat balance-spring. Dial, case and movement signed. Diam. 29 mm. (from Aniquorum.com).

This picture is from the book by Oswaldo Patrizzi "Collecting Patek Philippe Wristwatches", page 91, No. 397.
Hope to have been of help. Enjoy that beauty! Send it to PP Geneva, have it serviced and get an extract from the archives. This piece is intended to be a family heir. Pass it over to your son etc.
Best regards
