The Caliber 32 is Omega's premiere, reminiscent of the stopwatches used during the 1932 Los Angeles Olympics. However, the caliber not only measures short time periods, but also beats the elapsed time. Thus, Caliber 32 became the most complex ever created by Omega. Two models were equipped with the new caliber at once: the Speedmaster Chrono Chime and the Olympic 1932 Chrono Chime.
The mechanism, which was developed together with Blancpain (also part of the Swatch Group), is protected by 17 patents. The split timer is activated by a button at 2 o'clock on the Speedmaster or at 11 o'clock on the Olympic 1932.
The single pusher chronograph is operated by a button integrated into the crown. The note button that triggers the chime is at 5 o'clock on the Olympic 1932 Chrono Chime and at 8 o'clock on the Speedmaster Chrono Chime.
When activated, the hammers strike the golden gongs and strike the time. The hammers can be seen from the side of the dial. Seconds are beaten off by a single high-pitched sound, minutes by a low tone, and ten seconds by a double chime.
In the Olympic 1932 Chrono Chime, the new movement is housed in a 45mm Sedna gold case (the gongs are also made of this material). The hands are also made of Sedna, but covered in blue PVD.
The Speedmaster Chrono Chime is inspired by the famous Moonwatch Speedmaster CK 2998. The 45mm Sedna gold case is framed by a Grand Feu enamel dial. The aventurine dial has an inner bezel and counters in Sedna gold.
The watch comes with a special gift case made of walnut wood with a spruce plate that amplifies every chime of the watch, a magnifying glass for studying the details of the watch, a book and a travel bag.
