When it comes to watches, I have honed my own personal preferences down over the last few years. When it comes to case sizing, I tend to prefer something that falls under 44mm; when we are talking about complications, a GMT hand has become one of my favorites. The combination of those two items really is not a rare thing, but it is nice when they come together in a clean, legible package. That is exactly what we have in today’s review of the Butler Professional Series GMT.
