Hamilton Jazzmaster Quartz 40mm Black

The 40mm stainless steel case measures 7.8mm thick, finished in alternating brushed and polished surfaces. A sapphire crystal with anti-reflective treatment sits above the dial, and the construction delivers 50 metres of water resistance.

The black sunray dial throws light across its centre and absorbs it at the periphery — a quietly dynamic surface with applied indices and skeletonised hands. The design is intentionally pared back, with no date or sub-dial.

Power comes from the Swiss-made ETA F06.105 quartz calibre, selected for its slim profile and reliable battery life.

Mounted on a matching brushed stainless steel three-link bracelet with butterfly deployant clasp.
