There is a big gap between an eta 2892-2 and a piguet 1150. Unless you negotiate a price on a B.A.,you can maybe reach the $3000 for a wach fitted with a piguet movement.Otherwise you will not find a watch fitted wit ha piguet for under $3000.
Today many watches have almost all the same movements or base ebauches exceptions are blancpain and other very very high end brands who use jaeger le coultre,lemania and piguet ebauches.
See Panerai and Breitling who use the eta 7750 in a lot of their watches but I can consider a watch fitted with a 7750 as exceptionnal? No same for a watch fitted with an eta 2824-2. Today Omega is purely marketing, see their big railmaster chronometer in xxl size,what is the base movement? Just another eta,an eta unitas 6498-2, the most comment pocket watch movement of the cheapest quality. The best handwound movement ever produced was an Omega, the 30t2 built from 1939 till 1963 and so far superior in quality to any eta, jaeger le coultre, piguet and lemania movements.
I am not buying marketing I prefer to buy Omega authentic quality and this is often the case with the vintage stuff.
I have a movements approach rather than marketing approach.
But to each their own.
