The only reason it is not on the top of my Duometre charts is that it is a monopusher chrono. No matter if they are easier or more complicated to build than a two pusher Chronograph, they feel incomplete to me from s functional point of view. (Agreed that in 99% of all uses you do not need start/stop/start/stop cycles. But from that perspective you do not need a mechanical watch at all. )
Just my very personal point of view.
And that objection put aside the Duometre Chronograph is stunning with a wonderful movement.
