About Company
Most customers relied on Patek’s Chronoquartz T2 or boite pour ranger montres T3 units introduced in 1964, with two or three pre owned watch company separate modules, which were the backbone of Patek Philippe’s electronic master clock catalog. These independent quartz clocks cross-checked each other to verify they were within one-hundredth to one-thousandth of a second before sending a signal relaying the time to hundreds or thousands of clocks across a wider system.
