Introduction of silicon balance spring makes movement more durable.
Omega has increased the warranty on its Co-Axial watches fitted with the new Si 14 silicon movement to four years.
The brand said that it has been able to extend the warranty due to improved stability and long-term timekeeping performance created by the silicon balance spring.
Omega offers a three year warranty on watches with its standard mechanical Co-Axial calibre, which was developed in house and launched in 2007, and offers a two-year warranty on all other models.
The Si 14 balance spring is after silicon’s chemical symbol and atomic number and has qualities that Omega claims contribute to better performance than other balance springs made from more traditional materials. One advantage of using silicon is that it is not magnetic so the performance of a silicon balance-spring is not disturbed by exposure to magnetic objects. Also, while the performance of mechanical watches tends to deviate over time as a result of small everyday shocks, these disturbances have very little effect on silicon balance-springs.
From a horological point of view, according to Omega, there is substantial freedom in the fabrication of balance springs made of silicon that allows their geometry to be modified for optimal isochronism, the quality of oscillations occurring in equal periods of time. This isochronous quality reduces the amount of deviation in the watch’s accuracy.
