I hate the terms "tool watch" and "GADA". GADA sounds stupid and tool watch should be only used to describe things like Casios and such, not $8000 Rolex Explorers.
I love the Tudor GMT and don't think it's too chunky at all.
Grand Seiko is fucking up their good reputation with all the mental masturbation and releasing 100 different nature inspired dials per year. They are turning into the insufferable IPA Guy of watches. And they need to put micro-adjustment on all of their bracelets or I will never buy another one.
Oh please, they are far higher quality than Tissot and in the realm of luxury watches are actually a great deal.
