The Omega Speedmaster is one of Omega’s most iconic timepieces. Having been a part of all six lunar missions, the legendary Speedmaster is an impressive representation of the brand’s adventurous pioneering spirit. This model features a lacquered blue dial graced by a small seconds sub-dial at 9 o’clock and a 12-hour and 60-minute chronograph recorder on the sub-dial at 3 o’clock. There is a central chronograph seconds hand and a date window at the 6 o’clock position. A scratch-resistant sapphire crystal protects this bold dial. The polished blue ceramic bezel, with its tachymetric scale, is mounted on a 44.25 mm titanium and presented on a titanium bracelet. At the heart of this timepiece is the Omega Co-Axial calibre 9300, the first chronograph in the brand’s family of in-house Co-Axial mechanical movements. - Brushed/Satin finished titanium case with polished finished beveled edges. - Brushed finished titanium bracelet with polished finished edges. - Blue ceramic bezel with Tachymeter Scale. - Electric blue dial with stepped-down sub-dials. Sub-dial have a fine engraved concentric circle pattern finish. - Applied polished steel index hour markers with luminescent fill. - Printed white minutes/seconds & fractions of a second track. - Polished steel hands with luminescent fill. - Small continuous running seconds hand sub-dial located at the 9 o'clock position. - Date window displayed at the 6 o'clock position. Chronograph Stopwatch functions: - Large spear shaped tipped central seconds hand counter. - Minute & hour counters are combined into a single sub-dial located at the 3 o'clock position. Movement: - Omega caliber 9300, beats at 28,800 vph, contains 54 Jewels & has an approximate power reserve of 60 hours - thanks to its twin barrels mounted in series. - Column-Wheel Chronograph - column wheel is visible from the transparent case back. - The movement features Omega's "Si 14" silicon balance spring, which contributes to the movements outstanding resistance to shock and to environmental disturbances and thus, to the watch’s chronometric performance. - The movement also features the now-standard Co-Axial Escapement which contributes to greater precision, stability & durability. The Co-Axial escapement has less friction & reduces the necessity of lubrication thus reducing the time required between servicing. - The combination of the SI 14 balance spring & the Co-Axial escapement makes for an extremely reliable & stable movement. - The rotor & visible bridges are decorated with a unique "arabesque" wave design finish.
