Longines Conquest V.H.P. 43 Stainless Steel L3.729.4.76.9

V.H.P. stands for Very High Precision. Longines revived the name at Baselworld 2017 for a thermo-compensated quartz movement made exclusively for it by ETA and rated to plus or minus 5 seconds a year, against 10 seconds for the original 1984 V.H.P. The three-hand models launched that year use calibre L288.2, with a perpetual calendar that shows only the date, a battery rated for more than four years, and gear position detection, which puts the hands back in place if a shock or magnetic field knocks them out of sync.

The case is 43 mm with a sapphire crystal, and the lugs take a 22 mm strap. The Conquest V.H.P. 43 L3.726.4.76.9 is the same silver-dial steel watch on rubber without the ceramic, and the L3.729.4.76.6 is this steel-and-ceramic version on a bracelet. Black (L3.726.4.56.9) and blue (L3.726.4.96.9) dials come on the same rubber-strap steel case.
