Known as Spirate, a portmanteau of “silicon” and “rate”, the new hairspring has a proprietary form that allows a watchmaker to vary the tension along its length, theoretically enabling fine adjustment of up to a tenth of a second. The result is a watch certified to have a daily rate of 0/+2 seconds, the most stringent timekeeping criteria amongst Omega Replica Watches.
While it is a given that Omega debuts a new Speedmaster every year, several of them at a go in fact, the revolutionary innovation in the hairspring was unexpected.
The technical innovation behind Spirate is unquestionable, though the benefit to the wearer is probably less than the advantage it brings Omega in terms of streamlining regulation during production and assembly. And when Cheap Omega Replica starts equipping its offerings with Spirate on a large scale, it will be an achievement from the perspective of industrial production.
As for the Speedmaster Super Racing itself, well, the watch is less than spectacular. Visually it’s similar to existing models in the Racing collection, but dressed up with a bodykit that includes a honeycomb dial and italic font for the date. Like its counterparts in the line-up, the new Omega Speedmaster Replica is a large watch, too large in fact, at over 44 mm in diameter and almost 15 mm high. Omega could have made more of the opportunity to showcase a proper sports chronometer, but innovation took priority over design.
Spirate is a patented hairspring made entirely from silicon, essentially a more accomplished version of the Si14 silicon hairspring long used by Omega. Silicon hairsprings have been in use for almost two decades, so much of the innovation about them is concerned with their shape and regulation, particularly since standard silicon hairsprings cannot be regulated with traditional methods.
With Spirate, Omega Replica has created the first adjustable silicon hairspring. A watchmaker can adjust the tension, easily according to Omega, via a micrometer screw on the balance bridge, rotating the screw to increase or decrease tension within the hairspring. In theory, this allows the movement to be fine-tuned with a resolution of up to a tenth of a second.
Spirate presumably speeds up the regulation process during production. As the movement retains the variable-inertia balance, it can be first regulated via the balance and then fine-tuned via the micrometer screw. The same would then happen during servicing, reducing the lead-time for overhauls.
The Luxury Speedmaster Super Racing Replica has a 44.25 mm case that’s 14.9 mm in height, essentially the same case as the current Speedmaster Racing models.
The main difference lies in the dial, which is now a black honeycomb with generous yellow accents. The aesthetic is modelled on a concept watch presently in the Omega Museum that was an experimental watch built to withstand extraordinarily high magnetic fields of up to 160,000 Gauss.
The Speedmaster Swiss Replica Watches features a display back revealing the cal. 9920, a variant of the familiar cal. 9900 found across the Omega catalogue, with the key difference being the Spirate hairspring.
As is typical for Omega’s upper-end movement, the cal. 9920 is certified by METAS, making it a Master Chronometer. Besides chronometric performance, the certification also assures high levels of magnetism resistance.
