That is, the watch should not delay at all, and the upper limit is 5 seconds fast in 24 hours. The criterion of resistance to magnetic fields is innovative. Until now, the ISO 764 Horology — Magnetic resistant watches standard defines that an antimagnetic watch must support a magnetic field of 4,800 A/m, which corresponds to 60 gauss. METAS ...
Mathey-Tissot no longer produces its own watch movements in house. Instead, the company customizes mechanical and quartz watches with movements sourced from others. [4] Its logo is similar to the "peace symbol" of the Campaign for Nuclear Disarmament, but turned upside-down, with the words Mathey-Tissot in manuscript, above the printed words "since 1886".

Quartz movement of the Seiko Astron, 1969. The quartz crisis (Swiss) or quartz revolution (America, Japan and other countries) was the advancement in the watchmaking industry caused by the advent of quartz watches in the 1970s and early 1980s, that largely replaced mechanical watches around the world.
