This year 2019 OMEGA announced that it will bring back the iconic caliber 321, starting with a tribute edition to the aforementioned caliber in a platinum case of the Speedmaster model. Originally developed in 1942, OMEGA used this caliber in a few watches, including the original Speedmaster (until 1968 when it introduced the caliber 861), a watch that passed NASA’s demanding tests for use in space. Designed by Albert Piguet and Jacques Reymond, it was a resounding success from the start, until production ended around 1968. Based on the Lemania 2310 caliber, the 321 (along with its sibling, the 320) was the smallest chronograph caliber of its time, and featured a column wheel, Breguet balance spring, and beat at 18,000 vibrations per hour. The caliber 321 offers a specific 12-hour counter (achieving the chronograph look that today we consider classic, with three subdials), and was used in the Speedmaster, the Seamaster and in elegant chronographs like the one we offer.

OMEGA produced this watch on March 21, 1967 (serial number 24 million), so it was one of the last watches to include the caliber 321. It is offered with an OMEGA case from the 60’s, and with OMEGA’s certificate of authenticity (extract from files). It is in excellent condition, considering it is a watch over 50 years old, with all original components: silver dial in perfect condition, with a very light patina, never touched and with tachymeter from 60 to 700; original gold hands; original gold pushers; only the crown has been replaced. The caliber is in perfect condition, both in precision and chrono operation. Now you have the opportunity to access an elegant gold chronograph watch with an iconic OMEGA caliber.
