Rolex Syloxi hairspring
Silicon hairsprings have been round loads longer than 2014: Ulysse Nardin was the primary to introduce this wonderful feat greater than ten years earlier than (see Looking Back On 10 Years Of Ulysse Nardin’s Pioneering InnoVision Technology).
Although Rolex was a part of the identical Swiss analysis group, it took the Genevan large a little bit longer to get on board.
The Syloxi hairspring is a silicon and silicon-composite combine, designed to beat among the points confronted by a conventional hairspring, and it’s at the moment being utilized in Caliber 2236, which made its debut in 2014 in a women’ watch (see Always Expect The Unexpected: Rolex Surprises Yet Again With The Oyster Perpetual Datejust Pearlmaster 34).
Rolex explains: “Making certain the oscillator’s regularity is considered one of watchmaking’s nice challenges. It may well solely be achieved by minimizing the consequences of environmental disturbances that have an effect on the oscillator’s efficiency, notably temperature variations – which trigger supplies to increase or contract – magnetic interference, gravity and shocks.”
The Syloxi hairspring makes most of the identical claims because the Parachrom spring: it’s ten occasions extra correct when uncovered to shocks, impervious to magnetism, and presents higher stability when uncovered to temperature variations. Nonetheless, there may be a method it stands over and above the Parachrom: gravity.
Rolex has give you a brand new means for the Syloxi hairspring to turn into extra secure by altering the geometry to optimize the isochronism of the hairspring – which principally implies that the stability will preserve the identical time no matter amplitude.
Components that have an effect on isochronism are the escapement, incorrect poising of stability and spring, play between the curb pins and the stability spring, centrifugal pressure, and magnetic fields. The Syloxi spring attaches to the stability workers in a wholly new means, with out the necessity for a collet that has been pinned or glued, which reinforces the flatness and concentricity of the spring. It attaches to the stability bridge through two fastened factors versus one on a conventional or Parachrom hairspring, making it extra inflexible, flat, and centered.
So is silicon actually higher?
I conclude that silicon hairsprings are technically higher in each means.
They’re higher timekeepers throughout, much less affected by exterior forces, and put on much less over time.
I’ve just one subject with silicon hairsprings: they require advanced and costly manufacturing methods, making them restricted of their lifespan.
If a classic watch with a hairspring in determined want of restore or substitute involves a reliable watchmaker’s bench, it’s one thing that may be tackled. She or he might manipulate that spring or maybe lower, pin, and time a brand new one from scratch, thereby respiratory new life right into a basic piece.
With silicon that at the moment isn’t potential.
Nonetheless, trendy manufacturing is turning into easier, cheaper, and extra accessible by the day. Maybe 3D printers able to printing new silicon stability springs in a matter of minutes will probably be commonplace in all watch restoration workshops in some foreseeable future?
Silicon hairsprings are the best way of the longer term, although. Of that I’ve little doubt.
They do possess actual advantages for watches at present. Shoppers demand extra from all the things, together with watches, and the trade is listening.
I used to be as soon as a skeptic of silicon parts, however having seen timekeeping outcomes first hand I do know they’re right here to remain.
