Late 1930s Minerva featuring the renowned Cal. 20CH — a rare early waterproof chronograph with a two-tone dial in stainless steel.
This is a rare piece that features an early snap-back waterproof case—highly unusual for Minerva waterproof chronographs, which are typically seen with screw-back cases.
Despite its modest 33mm size, the snap-back waterproof case is equipped with a seemingly oversized crown and large pushers, giving it the distinctive character of an early waterproof chronograph. The dial showcases a classic two-tone design, with a blue tachymeter scale and a minute track rendered in different typefaces, exemplifying the charm of vintage aesthetics. The beautifully aged patina adds even more character and appeal.
Inside beats Minerva’s signature chronograph movement, the Cal. 20CH, known for its elegant curves and finely textured gilt finishing.
