Detailed Description
This Ultra-Chron is a stylish and technical dive watch, combining retro lines with cutting-edge mechanics. The cushion-shaped case and black dial evoke the classic 1968 Longines diver, now updated with modern materials and proportions. Applied markers and silvered polished hands, including the signature red minute hand, are luminous for high-contrast legibility.
At its heart is the high-frequency Longines Caliber L836, which delivers ultra-precise timekeeping and magnetic resistance thanks to a silicon balance spring. Certified as an ultra-chronometer, the watch exceeds conventional chronometer standards, ensuring outstanding accuracy.
The original stainless steel bracelet is equipped with a secure, triple safety folding clasp, showing minor desk rash typical of careful use. Supplementing the bracelet, this set comes with an aftermarket green rubber strap for a sporty look and a durable NATO strap for casual versatility.
