This is a waterproof chronograph from the 1950s made by Heuer, featuring the renowned Valjoux 72 movement and housed in a rare oversized 38mm stainless steel case. While most Heuer models from this era typically measure around 35mm, this one stands out with its larger 38mm screw-back waterproof case—a rarity. It is equipped with the legendary Caliber 72 by Valjoux, a movement widely used by many prestigious brands at the time, including Rolex.
The dial features a two-tone silver base with luminous Arabic numerals, offering excellent legibility. The aged patina of the luminous markers combined with the robust screw-back waterproof case evokes the feel of a military watch, giving the piece an exceptional vintage character. The evenly aged dial and the well-preserved case—with no signs of thinning—suggest that this was likely a one-owner watch, adding to its natural and authentic vintage appeal.
