The MC Geographic is the ONE that started it all for me just a few years ago. It got me hooked on JLC and into watches for real, or should I say "real watches," to misuse JLC's marketing slogan.
I ended up not getting the MC Geo and instead opted for the EWC, but that is my point here. Different strokes for different folks, especially with regard to travel watches. There has been a lot of discussion on this site about the various travel and GMT watches, and apparantly there is no perfect travel watch out there. Gee, what a surprise! So, the best thing to do is try on a bunch, study their respective features and decide for yourself which mechanisms work best for you. And most importantly let your heart decide which watch sings to you.
For me it was the EWC, although many can lodge very valid critiques of its travel worthiness -- not that I care in the least about such critiques, becasue I love the watch.
That MC Geo is a great piece if you like the subdial second time zone layout. This seems to me one of the most legible second-time zone watches around. It must be a popular design as at least a couple of other majors brands employ the same JLC movement in watches with almost identical dial layouts. Just sayin'. The design is sporty for sure -- the dial, the size and the compressor keys -- and it is also distinctively JLC. The water resistance is a nice feature if you are traveling with one watch and want to go swimming or snorkeling with it. The city/time zone selector gives you something to play with on the plane. It is just a great watch. I would still like to have one of my own.
JLC gives us many options for GMTs and second time zones, however. So, you wil have many choices, but I suspect that if the MC Geo is speaking to you, this will be a fine choice.
Let us know what you choose.
