Just my 2 cents but I’d be tempted to trade the annual calendar plus one of the date calatravas for a 3940 perpetual or for my very subjective taste the two date calatravas and the annual for a 5070. That trio would be tops. Classic manual calatrava, 5110...
At MSRP (though it might take a while to get, depending on your purchase history), the Aquanaut 5968 is for instance a spectacular option...for less than half of a PC😉
if the 5127 and 5296 both in WG, with 324 SC movements, and opaline stick dials, while both beautiful, is not somewhat redundant in a collection with normal budgetary constraints.
