![]() It is equipped with Japanese quartz movement and 7T92 calibre. Only then are they tested and selected, and only quartz oscillators that meet strict standards are used in the 9F quartz movement. Seiko Neo Sports Chronograph Black Dial Quartz SSB397 SSB397P1 SSB397P 100M Mens Watch. Seiko Quartz Chronograph SZER019 - mens watch manufactured by Seiko. Grand Seiko was the first watchmaker in the world to utilize quartz oscillators selected through this process.Īs part of the process, quartz oscillators made in-house are first 'aged' for three months, during which they are subjected to certain voltages so that their characteristics stabilize. Seiko Quartz Chronograph Gents Stainless Steel White Dial Bracelet Watch Case Size. Recognizing this, Grand Seiko introduced an aging process for its chosen crystals to ensure that the oscillators stabilize before being used. Seiko watches have long been the benchmark for watchmaking precision, quality craftsmanship. While the original was mechanical, Bulova utilizes its high-tech 262 kHz quartz chronograph caliber in the redux an impressive movement that boasts a smooth sweep and accuracy to within seconds per year. Other oscillators may perform with high precision at first, but undergo change in their oscillation over the years leading to inaccuracy. Seiko Classic Quartz Chronograph Men Watch SSB385P1. ![]() The accuracy of a quartz watch depends on whether the quartz oscillator can maintain a precise rate of 32,768 oscillations per second.ĭespite the overall regularity of this oscillation, each quartz oscillator has different performance characteristics, with some unable to maintain stable performance during the course of long use and changes in the environment. This is made possible by the selection of highly stable quartz crystals that are put through a rigorous aging process. QUALITY The 3-month aging process for quartz oscillatorsĬaliber 9F delivers an exceptional precision rate of ☑0 seconds per year.
