Manufactured in the 1950s, this Tissot chronograph is powered by the legendary Cal.27CHRO12 and features a 35mm screw-back waterproof case with a black gilt tachymeter dial. It houses the renowned Lemania Cal.27CHRO12—the same celebrated movement family that later evolved into the Cal.321 found in Omega's iconic Speedmaster.
The robust 35mm screw-back waterproof case and highly legible black dial with luminous hour markers evoke the design of the Omega CK2451, which was also supplied as a military watch to the Argentine Armed Forces. The black gilt tachymeter dial has developed a subtle tropical brown patina over time, giving the watch an exceptional vintage character and warmth.
Combining one of the finest manual-winding chronograph movements ever produced with a practical screw-back waterproof case, this outstanding timepiece is an excellent choice for those seeking a vintage chronograph that can be enjoyed in everyday wear.
