I suggested the sportier looks for some - not all - new Calatrava references, due to all the talk about PP wanting to guide new customers away from the Nautilus & Aquanaut lines.
Following the same logic, PP created the 5524 reference, so now maybe it's time for a true "entry-level", precious metal, sportier, 40mm Calatrava. If indeed this is the case and the design appealing, then maybe we are in for a good surprise.
