Invest in Jaeger-LeCoultre's 'Rendez-Vous' watch and you'll see it stand the test of time. Crafted from rose gold, it's powered by the label's in-house automatic movement for absolute precision and features an ellipse window that moves from sun to stars as day turns into night. The silvered dial is etched with a satin-like guilloché pattern radiating from the center and encircled with 60 glistening diamonds totaling 0.69-carats.
