Speedmaster Chronoscope Features:
The Omega caliber 9908 is found in Omega’s Speedmaster Chronoscope line of watches introduced on September 23, 2021. With all the press this piece has garnered upon release, collectors see a full list of functionality, but few take time to acknowledge where that functionality comes from: Not the movement. Many of the features on the Chronoscope have more to do with the dial and bezel design rather than the complications in the 9908 movement.
Bi-complex chronograph – two chrono counters side-by-side
Column wheel chronograph system
Double/twin barrels coated in DLC – extended power reserve
Certified Master Chronometer – Omega’s own chronometer spec
Full main plate with Geneva waves that spawn from the balance wheel rather than the center of the bridge
In conjunction with the standard chronograph functionality, the dial and bezel designs give the Speedmaster Chronoscope the following functionality…
Tachymeter (bezel) – ability to measure speed based on distance traveled
Telemeter (outer ring on the center of the dial) – ability to measure distance based on the speed of sound
Pulsometer (inner ring on the center of the dial) – ability to measure a human heartbeat
The Telemeter and Pulsometer are displayed in a snail-like layout that creates a central spiral on the dial (other brands offer this design as well). The three features listed above are where Omega gets the basis behind the name Chronoscope.
In Omega’s Own Words:
“The word Chronoscope blends two traditional Greek expressions. “Chronos” meaning time and “Scope” meaning to observe. The tool typically measures the duration between two points or events.” –source
The hour hand on the 9908 is set independently (great for changing time zones quickly without affecting the minutes). Pull the crown out one click to set the hour, pull it out two clicks to set the time.
In Omega’s Own Words:
“Manual-winding chronograph with column wheel and Co-Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. Silicon balance-spring, 2 barrels mounted in series, time zone function. Central hour, minute and chronograph seconds hands, small seconds counter, 12-hour and 60-minute counter. Rhodium plated finish with Geneva waves in arabesque.” –source
