Omega Speedmaster Chronograph Minute Repeater

The design of the Omega Speedmaster Chronograph Minute Repeater is inspired by the second-generation Speedmaster watch CK2998. It was a very memorable and well-known Speedmaster watch. On October 3, 1962, it became the first timepiece to accompany humans in space travel. The new Speedmaster has a 45 mm diameter case made of Sedna 18K gold, and a bracelet of the same material inspired by the famous "Nixon" bracelet. The bezel and dial using laser ablation technology are realized by filling the metal matrix with aventurine enamel glaze. The minute counter is at 3 o'clock and the small seconds counter is at 9 o'clock. There is a Sedna 18K gold hammer on both sides of the small seconds dial that is responsible for reporting minutes and seconds respectively (the 10-second reporting is completed by two hammers), revealing the identity of the excellent minute repeater on the front of the dial. However, it is not any minute repeater watch we have seen before, but a pioneering work that truly integrates timing and minute repeater functions - the minute repeater does not report the current moment, but a minimum of 1 second and a maximum of 1 second. 14 minutes and 59 seconds of time to tell the time. A single press sets the chronograph button at 3 o'clock, while the rattrapante button and chime button are set at 2 o'clock and 8 o'clock respectively.

If the Speedmaster series chronograph minute repeater has an extraordinary luxurious temperament, then the Olympic 1932 chronograph minute repeater is more classic and elegant. This timepiece composed of 640 components can be worn as a watch, or the strap can be replaced with a leather cord, the watch can be transformed into a pocket watch, or hung around the neck as a stopwatch - just like in 1932 Omega became the official timekeeper of the Olympic Games for the first time, as did the chronograph pocket watch unveiled at the Los Angeles Olympics. The white enamel dial is made using traditional techniques, which means that both the front and back sides of the dial are made of white Grand Feu enamel. Its chronograph display is the same as Omega's first chronograph watch launched in 1913. The small seconds dial has been moved to 6 o'clock, and the two hammers have also moved accordingly. There is a split-seconds button with a red ceramic ring at 11 o'clock on the case. Yes, this is also a split-seconds chronograph and a single pusher chronograph stopwatch. The button is located in the center of the crown.

Omega’s pioneering spirit is undoubtedly reflected in this movement, which consists of 575 parts and holds as many as 13 patents. According to Gregory, the project team decided early on to meet the high standards certified by the Master Chronometer, which means that the movement needs to be able to withstand strong magnetic fields of up to 15,000 Gauss. To this end, about 50 precision parts must be changed to non-magnetic materials. For example, silicon hairspring. Therefore, 7 of the patents are related to timing devices, and the remaining 6 are related to Master Chronometer certification. The task is difficult, because for complex and sophisticated timekeeping devices like this, traditional methods often use iron parts that can enhance the hardness. Another major breakthrough lies in the design of the coaxial escapement system. In the past, 4 Hz was considered the highest frequency of this system. However, with the help of electroforming processes such as LIGA, Omega was able to produce extremely precise tiny parts, breaking through the existing frequency. Finally, a tenth of a second timing display was successfully achieved. This reminds me of the coaxial escapement system developed by watchmaker George Daniels. At the earliest, only 15-20 watches equipped with it could be produced a year. Now, Omega has increased its annual production to 50,000 pieces, not to mention that it has now achieved an operating frequency of up to 5 Hz and the function of telling time for the first time. No wonder An Shiwen repeatedly mentioned that he believed that the Speedmaster series chronograph minute repeater and the Olympic 1932 chronograph minute repeater equipped with the 1932 movement "truly embody the spirit of Omega."
