You have the consummate Reverso, IMHO, the Grande GMT, and one of the most consummate Ultra Thins, the MUT Moon. I would go for the Master Compressor Geographic on bracelet (unless you prefer strap). It will have to be a gray market or used piece by now, but it combines 2 of the best things JLC has done:
(1) the Geographic is considered a "masterpiece" in the industry, and this version has the AM/PM indicator, which I prefer over the Day/Night indicator;
(2) the Compressor system of water proofing, which I think is awesome; and (if you get the bracelet) the gorgeous and comfortable Compressor bracelet with the Summer/Winter adjustment.
Lastly, it's 41.5mm which sits nicely in line with the Grande GMT, so it's sporty but not overbearing.
Just my thoughts.
