Maybe look at the AP 15300, a sporty dress watch w/ a fantastic inhouse 3120 movement w/ Black dial (My personal preference), or another color.
Depending on how large your wrist is, if you decide to stay around 40mm in dia, JLC is always a good choice.
I prefer dark/black dial watches, so for a dressy consideration:
Chopard Extra Plate: In House movement w/ Geneva seals
Other watches that are in double categories:
F.P. Journe CS Black Seal, or the New Octa 6 Black Seal w/ Small seconds, five day power reserve indicator, and large date is also one of my favorites.
Moser Large date w/ black dial is another consideration, another of my favorites.
The Patek 5107G is an awesome watch, but I really like it's counter part in the Richard Lange. Beautiful watch, chronometer, larger balance wheel, and all who have given their owners impression, that I have read, say, its regulations is spot on, +/- :01 a day or less. I believe, however, it is substantially more costly than the 5107G.
Try each one of your choices, and try on a few others, see how it looks on your wrist, close your eyes and see how comfortable it is, then your choice will be easy...........maybe! :)
Good luck and Best Regards,
Kevin
