What is your favorite JLC watch for mechanical "content?" I'll start:
Reverso Grande GMT
Why? 8 functions: Home-Time, sweep seconds, day/night indicator and large date + 2nd timezone that can advance or retard at the press of a button, reserve de jour, day/night indicator, differential subdial showing how many hours ahead or behind home-time, with an 8-day power reserve (which really should make it 9 functions), on 2 very legible, NOT BUSY dials.
What's yours?
