Built as Jaeger-LeCoultre’s first perpetual calendar ever to join its sporty Polaris line, this piece does what almost no other watch dares, dropping a no-reset-until-2100 complication into a steel sports case you can actually swim in. Carrying JLC ambassador codes from Kim Woo-Bin and that “Stellar Odyssey” chapter, it stays a rare grail that never asks you to baby it. Think of it as a watch James Bond would wear on his day off, gadget-grade brains hiding behind an easygoing blue face.

Presents itself in mint condition with little to no signs of wear. That gradient blue lacquer dial shifts from bright center to deep ocean edge like a Christopher Nolan sky, with four counters each textured differently so light dances across them. Skeletonized, luma-tipped hands float over trapezoidal Super-LumiNova markers that glow like a control panel at night. And that opaline inner bezel, with its flash of orange and red security zone, lends this whole package a quiet Top Gun cockpit energy.

Functions cover hours, minutes, seconds, perpetual calendar, date, day, month, year, dual-hemisphere moon phase, and a rotating inner timing bezel. Two crowns handle everything: a top crown spins that inner bezel for timing, while a lower crown winds and sets time. A single recessed corrector, pressed with its included tool, quick-sets every calendar indication and moon phase at once. Just never touch it when that red zone shows, or you turn 351 parts into a snow globe.

Comes as a complete set, double-boxed with warranty card, instruction manual, guarantee booklet, and whitetag.

Made for a collector who refuses to choose between brains and brawn, this is one complication that survives a Monday. Swap its steel bracelet for that blue rubber strap and it goes from boardroom to beach faster than a Marvel costume change, a true in-house perpetual calendar that begs to be worn instead of locked away. For anyone chasing a “thinking man’s grail” without dress-watch fragility, few pieces argue their value this convincingly.
