Hamilton Watch American Classic Jazzmaster Day Date H42565731. The American Classic collection was produced by the expert designers at Hamilton watches as a symbol of their achievements in providing reliability on the tracks of Americas railroading system. This new Hamilton Jazzmaster watch wears a contemporary case constructed from brushed stainless steel with wearer friendly dimensions of 42mm in diameter. The onyx black lacquered dial is deeply intense, hosting 12 slender petal like batons which embellish the outer perimeter of the dial. Silver hour and minute hands grace over the day display which has been mounted against a white backdrop, forming a soft arc underneath the 12 o clock location. The date aperture sits above the 6 o clock location offering a truly unique interpretation of time and adding balance to the beautifully applied proportions. The Hamilton Jazzmaster, like all Hamilton watches, has been created with precision and reliability at the forefront of its design, thanks to the automatic H 40 calibre which delivers 80 hours of power reserve, protected within its 50 meter water resistant stainless steel armour. The Hamilton American Classic Jazzmaster Day Date is executed perfectly on a genuine black leather strap and stainless steel pin buckle.
