The Tudor Big Block Chronograph Reference 79180 is a stainless steel chronograph introduced in the late 1980s (specifically succeeding the 79100 series) and produced until 1995, serving as Tudor’s first automatic chronograph and a counterpart to the Rolex Daytona. It is nicknamed the "Big Block" due to its 40mm case thickness of 14.5mm, which was necessary to house the automatic movement, and features a steel tachymeter bezel, acrylic crystal, and a case design sharing heritage with Rolex Oyster cases.

This 1994 model comes with original box, outer box, and papers.
