But if chosing a 'simple' (no other complication) perpetual, I would go for the Moser.
The Jaeger LeCoultre is a bit too thick and the dial too busy for my liking, and I realy like the 'understatement' of the Moser (you can't really tell it is a perpetual calendar beacause it doesn't have many dials, but it still is a perpetual calendar, which achieves its perpetual functionality without any show-off)
I think I would even have removed the power reserve indication on the Moser dial, to keep only the basics: H/M/S / date (perpetual)
