Worth considering whether you need “true”/“traveler” GMT functionality versus “caller”/“office.” There are a lot more caller GMT’s out there at a lot of different price points. There are fewer true GMT’s and they’re generally more expensive, but there’s more variety with those than there used to be.
One of my favorite options is the Monta SkyQuest in its various flavors. This is a caller GMT though, so maybe not ideal for every use-case.
