USD <8k if not original buckle included, preferably ~6k
I consider these estimates to be far too high. Consider, among other things, that the cal. P1019 is arguably the least desirable V&C automatic caliber. It was sandwiched in between their high-class bumper movement, and the 1071/72 calibers that were among the very best produced during the peak of early-mid 20th century watchmaking. The latter two also featured beautiful gold guilloche rotors, with AP and Patek Philippe being the only other manufacturers to employ such extravagant finishing.
Furthermore, judged by the modest quality photos, the rest of the watch is not in especially fine condition.
You can look at auction results (which often tend to be inflated) of the same reference, and note that even in recent years, good original examples have typically sold for <$5000.
As just one example, this very similar watch, with the same movement, original, and in better condition, sold recently through a major auction house for ~$5100
including the buyer's premium!

In my view, the watch being considered by the OP is worth no more than $3500.
