My point of view, being not at all a PP expert:
- I don't understand why this is a Calatrava, and not part to a more sporty new family. Calatrava for me is only for very traditional models
- the hobnail case band doesn't really work, it would suit better less sporty model
- the movement, yes simple, is great to look at, and 8 day power reserve is a great thing to have as an owner.
Best,
