Matted wide and narrow, highly polished elements in between that taper towards the clasp. With the Omega Speedmaster you should pay attention to the water resistance, as is the case here with the Chronoscope, which is only waterproof up to 5 bar.
A harmonious dial, leaf-shaped hands, three scales, totalizers and a fine spiral pattern behind the Arabic numerals can be found here on the Chronoscope. The hand-wound Omega Co-Axial Master Chronometer caliber 9908 is the heart of this measuring device. With a power reserve of up to 60 hours, you can go exploring. The Omega Speedmaster Chronoscope has a time zone function, a central hour, minute and chronograph second hand, a small seconds hand, and a 12 hour and 60 minute counter.
Three scales each complete the technology of the hand-wound chronometer. The well-known external tachymeter scale is used to measure speed (unit per hour). The scale below the Arabic numerals is the Telemeter scale. This is used to measure a distance from an audible and visible feature, such as a thunderstorm. The last scale, exactly below the telemeter scale, is the pulsometer scale, which is used to determine the pulse beats.
