Extra flat calibers are a classic goal in watchmaking

I would, and have actually, choose a micro rotor movement over a cantral rotor one.

With a micro rotor the whole watch becomes very slimm.
In your list a microrotor is missing from AP (and I wonder at the monent if has got an micro rotor movement at all).
But AP makes it up with a cleverly designed central rotor movement and achieves a movement of just 3mm height.
Patek's 240 is around 2,45 or 2,5 mm high and slimmer than your mentioned Breguet movement.
That makes it the thinnest of all mentioned movements.

What is nice about your mentioned Breguet movement is the open barel, which is not used often.

Reliability, accuracy and finish are nothing to worry about at this level of watchmaking.

My choice: Patek's caliber 240.

Tell us what you went for.

Breguet Classique 7337

All, I am weighing the purchase of a Breguet Classique 7337 (fitted with Caliber 502) against several pieces from Audemars Piguet (fitted with Calibers 2121 and 3120) and Patek Philippe (fitted with Calibers 324 and 240). I would very much welcome feedbac...

Curious to hear the views of more knowledgeable folk

It's a hard comparison since the movements have varying levels or types of complication. In terms of finishing I don't think there are significant differences based on what I've seen for movements at this price point from these brands. Nice choice with th...
