As a French living in Canada, I used to go back to Europe several times a year (pre-Covid) and a true GMT would have been useful indeed. I'll keep the B&R for the time being, as it's very practical to have both times, but once we can fly in good conditions again, I might sell it to fund a true GMT
I'm also French in Canada.. In Toronto. And I also travel a lot to France as I work in West Africa, so on my way to sites I would stop in France every other months. Just did my first trip in over a year, so I'm completing today my 14 days quarantine..
Back to the watch, I don't mind not having a "true" GMT fonction actually, since I switch both local hour and GMT hour when travelling. It seems the true GMT is very practical when you do multi destination trip, so that every time you land in a different time zone you can change the local hour hand with the 1h increment, and keep the GMT on home. The cheapest option is probably the Omega SMP GMT from 2006-2010, and this was the one I was hesitating between B&R and Omega. You can find it used at aounr 3000USD, so not too much of a stretch compared to the B&R. But I just like the design of the B&R much better.
And yesterday I received the black dial version! Now that I have both in hand, I definitely prefer the black dial (so I'll be selling the blue dial soon if anybody is interested).
Cheers!
