High precision is, in fact, exactly what this new Longines Conquest VHP is all about: it is accurate to ± 5 seconds per year. Let’s keep in mind that COSC requirements for quartz movements are ± 0.07 seconds per day, which translate into ± 25.55 seconds per year. The new L288.2 three-hands and L289.2 chronograph calibers clearly outperform certified quartz chronometers. The Grand Seiko SBGX093 Quartz, the Bulova Moon Chronograph, and even the ETA Precidrive or the Omega Spacemaster Z-33 come to mind because they are all high-precision quartz movements, but none to the degree of the new Longines VHP calibers. The Grand Seiko, Bulova, and Omega watches I cited are accurate to a very impressive ± 10 seconds per year or about half that of the Longines VHP… More at A Blog To Watch.
This watch, and others like some of the Grand Seikos, begs the question of how much people should reasonably spend to get the same level of accuracy as a £100 satellite watch. I understand why they would though.
