Gray is the quiet power color of watch dials, and the Hamilton Jazzmaster Auto Chrono H32596181 uses it brilliantly. The gray sunburst face shifts from silver to charcoal as the light changes, giving this 42mm stainless steel chronograph a sophisticated, almost architectural look on its matching steel bracelet.

Hamilton's H-21 automatic chronograph caliber does the heavy lifting. It winds itself as you wear it, offers a generous 60-hour power reserve and handles the stopwatch, small seconds and date with mechanical precision. An open caseback puts the movement on show, while sapphire crystal and 100 meters of water resistance make it far more durable than a typical dress chronograph.

The full steel bracelet gives this reference a sportier, more versatile character than the leather versions. It is ideal for someone who wants one automatic chronograph that can go from the office to the airport lounge to a weekend on the water.
