Good GMT watch options

I'm noodling around, looking for a good goldilocks GMT watch. I don't have any problem with something like the Seiko SSK models, but I lean toward something that doesn't look like a standard dive watch with an extra hand. Watches that appeal to me in this category include the Nezumi Aviera, Nodus Sector, Monro Adventure, Boldr GMT.

I'm looking for an automatic that is <$500, preferably sapphire crystal. Are there other watches I should consider, or does my above list cover it? Thanks!
