This is a late 1990s to early 2000s Ulysse Nardin Marine chronometer in stainless steel, which was just cleaned and is accurately keeping time. The 37mm steel case displays excellent condition. This watch features a coin-edge bezel, sapphire crystal, date indicator, power-reserve indicator, blued steel hands, and screw-down crown. The 28-jewel Ulysse Nardin caliber 11 1/2 UN-26 automatic movement boasts a 42-hour power reserve, quick-set date, and hacking seconds at 6:00. This movement meets COSC (Contrèle officiel suisse des Chronomètres) chronometer standards. The original buckle is included and installed on a new generic band.
