Smoothness of Sweep

[poopie]

I am a newbie who, over the past few years, have fallen in love with mechanical watches. I am now the proud owner of a few of these toys, including an Explorer II M and a SubC.

My passion is driven by the smooth sweeping hand of a mechanical watch. Somehow and on some level this connects with me, reminding me that time is a continuous and not discrete measure.

I'd like your opinion as to which watch/movement you believe has the smoothest second sweep. I'm not sure which technical attributes are at play here (#of vibrations, different balance wheels, etc.) but I seem to observe that my Breitling Cockpit has the smoothest sweep of my collection, even compared to my two rollies. Your thoughts?
