The movement cal. 1014 has been in use with many modifications for at least 25 years. It did not feature the option of a free-sprung escapement and it does not appear that V&C produce it under Geneva hallmark of quality. But it was of course finished to the high Genevois standard in all other regards. The 1014 was the backbone of Vacheron Constantin’s production of manual wristwatches for a long period of time (early 70's to mid 90's).
JLC shared the base movement also with Breguet, Chopard and probably others alike.
Anyway you could rarely get the 70's style V&C refs with movement for choice, so you have to take what is out there.
In terms of price, it is a real bargain compared to a used JLC, often cheaper, in better condition, and with a quite high, usually better, grade on refinement.
