Question about the movement Breguet 5140
Hi,
Here is my new Breguet.
I read many discussions about the movement of this watch and I have some questions.
Breguet say this is a Caliber 240 Q Ultra-thin self-winding mechanical movement.
I read on other messages that the movement is a Piguet 71. Is it the same with a different name ?
What is exactly the history of the movement in this watch ?
Thanks

that sounds nice! A question please John:
Hello John, reading you answer I wondered how You would compare the cal 502(FP 71 based) to the cal 591(Lemania 8815 based) in terms of service,mvmt design etc(improvements done by Breguet to the old 8810/Longines concept of Your in-depth review?), kind r...
I prefer the Cal. 591
Hi lutz, The cal. 502 is just too thin for its own good in my humble opinion and suffers slightly decreased accuracy and reliability because of it. It is a highly serviceable design in the sense that everything is exposed and easy to get to (which is not ...
thanks John
and do You know of improvements to the original 8810 version? kind regards, Lutz
