: It is the ref 74033 b with valjaux 7740, you
: can easily figure out this movement-type by
: a look on the pushers: the lower pusher of
: the 7740 is far lower placed than the lower
: pusher of the ref 73633 monaco...and of
: course it has the date feature...this means
: the case of this monaco is also diffrent to
: the ref 73633 case. the val 7740 monaco is
: the only monaco w. crown at the right side
: and the date feature. the val.7734 was never
: used for the monaco.

As Ralf points out, the pushers on the 7740 Monaco are spread further apart than the 7736. In fact their position is the same as on the cal 11/12 automatic versions. This is because the 7740 uses the same, or very similar, chronograph module placed onto a manual wind movement. Why the 7740 was used by any manufacturer, is a bit of a mystery. Breitling used it for Navitimers (with a third sub dial giving running seconds) as well as the Pult and a few others besides.

i have no idea what the base movement is, does anyone else know?
