Longines would certainly be my first choice with these criteria, but at a lower cost and different look, I love the Mido Ocean Star Decomp Worldtimer - also a (flyer) GMT, decent 80 hour power reserve from the "in-group" movement.
I have the U4 regular / non-limited edition and love it as a travel / holiday watch. I normally have it on a regular NATO or rubber NATO and find it very wearable / comfortable and despite lots of bangs and scrapes, it's pretty accurate for the movement - around -2 to -5 spd. Also works well with the Forstner ladder bracelet I just got for mine. Looks like I got a good one on QC, but I haven't heard of any problems anecdotally.
Hopefully they will get the issues resolved for you - really like the look of your U1-FAI.
They are clearly not to everyone's taste but I think it being a bit unusual is part of the attraction for me and I think the price (at least on the regular editions) is very fair.
Agreed - such a shame that both of Nomos's "travel" watches (this and the Zurich) are just splash-proof; travel and holidays often involve water - I rarely take my watch off while traveling. GS have some great GMT watches in budget, with decent swim-ability.
For me it would be the Nomos. Truly interesting small independent manufacturer. I love the way they have implemented the GMT complication on the Tangomat. The Louis Erard would be my second choice, GS third. I have nothing at all against Tudor (and am very tempted by the Pelagos FXD). Nomos makes me smile the most!
