difficulties tracking down the Timewalker GMT. It is Montblanc's most popular model! But I am sure if you pressed hard enough your local Montblanc authorized dealer can find one faster

I don't have the exact pictures you are looking for but if you are trying to see what it would look like on the wrist, I have a few substiute photos. Here is the Montblanc Timewalker Automatic. It is very similar in layout (only missing the GMT hand). The case size is the same except the Timewalker Automatic is 0.5mm thicker.



Another model to consider is the new DLC coated Timewalker GMT Big Date.

I hope you will keep us up to date on your progress and see the Timewalker GMT on your wrist soon!
Best, Mike

That red tipped GMT hand is extremely legible at a quick glance in your picture. Sounds like a perfect watch for your needs.
Btw, is the red tip luminous? Or just paint?
Cheers,
Anthony
If I am half asleep because of jetlag and I'm trying to get a quick idea what time it is locally, I wouldn't want another luminous hand confusing me.
During the daytime, I'd be interested in what time it is at home.

Montblanc wishes to attract with the Timewalker GMT.
Thanks for posting your wristshots.
