Why Collectors Love This
A vintage Tudor chronograph with a distinctly muscular profile, the Oysterdate Big Block reference 79170 is prized for translating the brand's tool-watch sensibility into a sturdier automatic format. This watch pairs a 40mm stainless steel case with a black dial, giving the design the crisp, utilitarian look collectors expect from the model. The automatic movement drives the chronograph and date, reinforcing its practical, everyday focus. At 14.5mm thick, it wears with the substantial stance that defines the Big Block name.
