Author POV

At 39mm, this is the size I keep pointing to when people ask what a correctly proportioned GMT case should measure — close to the wrist, no overhang, and the black-and-burgundy bezel reads as a genuine two-timezone tool rather than a styling exercise. The steel three-link bracelet adds wrist presence without tipping the package into oversized territory, and 200m of water resistance means this one isn't precious about daily wear. In-house automatic movement, GMT hand — on the axes I use to score a travel watch, legibility and proportion both land solidly. It's the bracelet, more than the dial, that separates this reference from its rubber-strapped sibling.
