Turquoise is having a moment, and the Hamilton Jazzmaster Performer Auto Chrono H36656140 is one of the most appealing ways to wear it. Hamilton describes the dial as light blue; in person it reads as a fresh, ocean-like turquoise that brightens a steel sports watch and feels right at home in summer.

This is a fully mechanical chronograph powered by the Hamilton H-31, a Swiss automatic caliber with a 60-hour power reserve and a Nivachron balance spring. Three subdials and a date window sit on the dial, a tachymeter scale rings the bezel, and the screw-down crown brings water resistance to 100 meters. An open caseback shows the movement at work.

The 42mm stainless steel case measures 15.22mm thick and is matched to a steel bracelet with a butterfly buckle, giving it a solid, sporty presence on the wrist. It is a confident choice for a collector who already has the black and blue basics and wants color with credibility.
