Hamilton Jazzmaster Open Heart Auto 40mm Blue

The smoked blue dial draws the eye to precise cut‑outs that reveal the movement. Applied markers, polished hands, and a clean minute track keep it elegant and easy to read. The 40 mm steel case slips under a cuff and suits both casual and formal looks.

Power comes from the H‑10 automatic with an 80‑hour reserve and Nivachron for improved anti‑magnetism. Water resistance is 50 metres, and the watch features an exhibition caseback and sapphire crystal. A supple leather strap with a pin buckle completes the balanced, modern dress design.
