Introduced in 2006, the Speedmaster Rattrapante Co-Axial model in steel evokes the original 1950’s models with its classic curved horns and round polished push-buttons. Add to this the column wheel chronograph with vertical coupling function, the Co-Axial escapement and a COSC certificate.
By allowing one watch to record two or more events, the Rattrapante (or split-seconds) that was introduced in 1930, helped eliminate discrepancies between two chronographs in sports timing. Likewise, the column wheel introduced in 1898 into a pocket watch, allows precision start, stop and reset functions of the multiple hands of the chronograph. Sports enthusiasts today can time laps or two events without resorting to a second timekeeper while the tachymeter scale allows average speeds to be calculated over a set distance. Furthermore the red Pulsometer scale on the dial serves to take pulse readings.
This watch is driven by a mechanical movement, in this case the self-winding Omega calibre 3612. The Co-Axial escapement, technology that is exclusive to Omega, represents one of the most important advances in watchmaking over the last 250 years.
The Co-Axial escapement considerably reduces friction in the heart of the watch mechanism and offers improved long-term reliability and accuracy. Performance is further improved by a free-sprung balance that allows for more precise adjustments of the watch. The watch has a 52-hour power-reserve and the white rhodium-plated movement is finished to luxury standards with special waves, circular-graining and gold plated engraving. The screws and the column-wheel components are made of blued-steel and the movement is visible behind the sapphire crystal case back.
Two versions of the dial are available with black counters against a silver dial and vice versa, allowing for easy reading of both the chronograph and time functions. The red Pulsometer scale running around the outside of the dial provides another useful function and the fixed brushed stainless steel bezel incorporates an engraved tachymeter scale. Luminous, facetted and diamond-polished Broad Arrow hour and minute hands are easy to read while the red tip of the split-seconds hand allows precise readings to 1/8th of a second and the date window is positioned at 6 o’clock. The Omega logo and hour markers are applied to the dial.
The polished and brushed stainless steel case has a diameter of 44.25 mm and is water resistant to 100-m/330 ft and incorporates a watertight double-gasket crown. The domed and scratch-resistant sapphire crystal has an anti-reflective treatment. A third push-button at 10 o’clock activates the split second function.
The Speedmaster Rattrapante Co-Axial is available on either a satin finished stainless steel bracelet with a safety clasp or on a brown over stitched calfskin strap with a fold over stainless steel clasp.
