In that case, the movement will schedule a self-test the next morning at 3 am exactly. The hands spin like crazy as the Conquest ensures that “the reference time is correct and accurate.” Unless, of course, there’s an impact (large or small). And that’s not the end of it.Įvery three days, at 3 am exactly, the L289 movement self-tests. Push the crown back in and the hands return to duty and the date corrects itself. The hands gather at 12 as the battery goes into sleep mode. To forestall mortality, pull out the Conquest’s crown out for two minutes. When the Conquest’s four-year battery nears end-of-life, the second hand jumps in two second intervals. If one of two sensors detects a disruptive magnetic field, the L289 stops the hands until the danger passes, then returns them to their correct position. movement too hard, its gear position detection system restores the dislocated hands to their correct position.
It’s five times more accurate than the Swiss COSC requirement of +/- 0.07 seconds variation per day. It destroys the average quartz watch’s +/- 10 seconds per month accuracy. The new model improved accuracy variation to an astounding +/- 5 seconds per year.ĭeveloped in conjunction with SWATCH stablemate ETA, Longines’ thermo-compensated caliber L289 is insane. At Baselworld 2017, Longines reacted to the ongoing Smart Watch Crisis by unveiling the second gen Conquest V.H.P. (Very High Precision) wowed horologists with +/- 10 seconds per year accuracy. Introduced in 1984, the original Conquest V.H.P. If accuracy’s your jam and money’s too tight to mention, check out the Longines Conquest V.H.P. We’re also talking thousands of dollars and zero availability. We’re talking about a timepiece boasting +/- one second per year accuracy. Citizens’ Caliber 0100 is the world’s most accurate watch (that doesn’t sync to an external source).
