I saw that JLC at an AD once, and didn't like the subdials in life-size. They look great on our computers monitors in blown-up zoom... but when I had it on my wrist, looking down at it from 2 feet away, it didn't feel particularly special. The date wheel especially, felt discombobulated with its different spacing between 1-digit and 2-digit dates. If it were a wall-clock, I'd have better appreciation of the JLC dial format. But in minuscule life-size, looking at the dial from 2-3 feet away, the dial felt very emotionless.
Also, I get tremendous utility + personal enjoyment from 15,000 gauss resistant watch. The JLC I owned for 2 years, a Reverso duo-face, was always getting magnetized everytime I went through an airport. It got to the point I was taking a demagntizer in my carry-on, anytime I wanted to wear the JLC while traveling... I'm sure this watch in the Master Control range will be more robust & durable than the Reverso, but I'd nonetheless take Omega's movement for its magnetic resistance.
