Zenith - El Primero Stratos Flyback Rainbow

0 0 Tuesday, 8 July 2014 Edit this post

The new Zenith El Primero Stratos Flyback Rainbow is the updated reinterpretation of the Rainbow Flyback model which the Manufacture headquartered in Le Locle built in 1997 based on technical specifications established for the French Air Force for a high-performance timepiece capable of standing up to the most extreme conditions - including violent accelerations from 9 to 11 g’s, variations in pressure and temperature, as well as vibrations and magnetic fields.

The original Zenith Rainbow Flyback dating back to 1997

The 45.5 mm steel case is topped by a rotating bezel bearing an aluminium ring. Total thickness is 14.10 mm. The domed sapphire crystal is glare proofed on both sides. The transparent engraved sapphire case-back reveals the El Primero Calibre 405 B automatic movement beating at the exceptional speed of 36,000 vibrations per hour and thus displaying 1/10th second precision, an achievement that makes it the world’s most accurate series-produced chronograph since its creation in 1969 to this very day.

The El Primero Stratos Flyback Rainbow is also equipped with a date display, a telemetric scale, and of course with the flyback function which enables pilots to stop, start and restart the chronograph at a single press on the push-piece, compared with three presses required for a standard chronograph.

The minutes counter at 3 o’clock appears in colours enabling night-time readings in infrared-lit cockpits, exactly like the first model, while the hours are displayed at 6 o’clock and the small seconds at 9 o’clock. The white Super-LumiNova Arabic numerals and the red chronograph sweep seconds hand stand out against the black of the dial for perfect legibility.
