What impresses me the most is that despite being all in the same MC series, each expresses a different forte impressively well. If it is MUT, then it was about elegance and finesse; if it is the triple calendar, then it is rearranging a classic proportion of 32mm into a 37mm--not a straightforward task when the movement, case and dial were all larger by a few scales. Yet nothing appeared lost, and people came to accept this classic watch in the new proportion. And if it is the alarm, how to integrate some of the high-end MR mechanics into a far more accessible alarm watch while providing a display crystal for admiring that feat at a 37mm size. These are serious considerations to details and horological expressions that have somehow been lost across time.
