Hamilton Jazzmaster Open Heart 40mm Mens Watch Green

Ref. H32675560

The Jazzmaster line has always occupied a particular place in Hamilton's catalogue — dressed up enough for a dinner table, grounded enough to wear daily without ceremony. This Open Heart variant takes that brief and cuts a window into it, letting the H-10 movement show through a smoked green dial that shifts between translucency and depth depending on the light. The H-10 is Hamilton's own calibre, built with an 80-hour power reserve and a Nivachron balance spring that shrugs off magnetic fields — which matters more than it once did, given how many everyday environments generate them. At 40mm with an 11.05mm profile, it sits neatly on a range of wrists without the thickness that skeleton dials sometimes carry as a penalty for their architecture. The brown leather on a silver steel case is a considered pairing: it pushes the watch toward the warmer end of the palette, which works well against the green. The transparent caseback means the movement is visible from both sides, and the 80-hour reserve gives it the better part of a long weekend unworn before it needs winding.
