The Jaeger-LeCoultre Rendez-Vous Classic Night & Day model Q3448431 features a charming day/night complication set within a 34 mm stainless steel casing. With its smooth bezel, gently curved sides, and flat lugs, the case exhibits a thickness of 8.63 mm. Adorning the bezel and a ring on the dial are 107 diamonds, meticulously grain-set to total 0.84 carats, while its water resistance is rated at 50 meters.

The dial presents a beautiful silvered-gray finish that merges both sunray and guilloché textures. It is decorated with floral-inspired numerals and cabochon-shaped hour markers that frame blued stick and floral hands. Prominently, at 6 o'clock, blue motifs of the sun and moon represent the day/night feature. This watch is powered by the automatic Jaeger-LeCoultre caliber 898, handling hours, minutes, seconds, and the day/night indication. Operating at a frequency of 28,800 vibrations per hour, it boasts a power reserve of 70 hours. The Q3448431 reference is complemented by a blue alligator leather strap, which is interchangeable, along with a stainless steel double-folding clasp.
