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.
