Omega Specialities Olympic Collection

This edition features the Arabic numerals and the red OMEGA name and logo and has an extraordinary striking feature : the five interlocking colored Olympic Rings are mounted on the counterweights of the central chronograph seconds hand and the inscription "Official Timekeeper" is stamped on the case back. Comparing to the professional diver’s watch (300 metres/1000 feet) this model is water resistant to 600 metres/2000 feet. Other features of this watch are the screw-in crown and screw-down case back, the helium escape valve, the fluted uni-directional rotating bezel featuring a luminous dot and the highly visible hands on the dial. Positioned at 10 o’clock and embossed with the chemical symbol for helium “He”, the helium escape valve allows any atoms of this gas to escape during decompression. This is a vital function when using a diving bell, as minuscule helium atoms are able to penetrate the case and could damage the watch when expansion occurs during decompression. The chronograph push-buttons, made of steel and decorated with a coloured aluminium ring, are functional to 600 metres/2000 feet while the domed scratch-resistant sapphire crystal has received an anti-reflective treatment on both sides for optimum clarity. The matt black dial offers excellent contrast thanks to applied luminous hour markers and the use of Arabic numerals in white. The date window is positioned between 4 and 5 o’clock. The facetted rhodium-plated arrowhead hour and minute hands have SuperLuminova inserts and a highly visible red tip further enhances the luminous arrowhead seconds hand. Along with the luminous dot on the bezel, the high visibility of the markers and hands are invaluable for measuring precise dive times, even when descending to the darkest depths of the ocean. This watch is fitted with the Federic Piguet based Calibre 3313 high-quality self-winding mechanical movement which has a power reserve of 52 hours. The Co-Axial escapement, proprietary Omega technology, considerably reduces friction in the heart of the watch mechanism and offers improved long-term reliability and accuracy. A free-sprung balance further improves this COSC-certified chronometer. The column-wheel mechanism serves to perfect the chronograph’s performance. It ensures a smooth start to the sweep of the seconds hands when the chronograph is activated and provides precision stop and reset functions. The rhodium-plated movement has been given a luxurious finish and the bridges are decorated with attractive circular graining, Geneva waves and gold-plated engravings and the screw-down case back features a seahorse medallion. Diameter of the watch is 45.5mm. It comes with a comfortable unique Omega rubber strap with white stitching and a stainless steel fold over safety clasp. Watch is in a mint condition with all functions running perfectly. It comes with complete documentation including Omega Olympic Official Timekeeper booklet, Warranty card, Pictograms, Chrometer Certificate and the original Omega Olympic box.
