Breguet XX
My favourite movement, good history, nice from the front but overloaded with 'posh' detail touches that would get on my nerves from the moment I strapped it on. It's too large and too tall, but lordy do I fancy one.
In fact, on reflection, they are the anti Rolex for me. I'm besotted by the brand, but I can't think of a watch they have made in this century that doesn't irritate me in some way or another. Even their older stuff is undermined by the intimate links with Dent and the fact that you can still pick up a decent old Dent with change from a grand while old real Breguet start at the cost of a northern house. Rolex, there are few older sports models I don't like, while the brand need to be publicly whipped.
