Built at the request of scientists at CERN, this piece shrugs off magnetic fields that stop lesser watches cold, and wears an orange lightning bolt for a seconds hand while doing it. Retired in 2023 with nothing lined up to replace it. Collectors who already own the safe answers tend to want this one next.

Presents itself in mint condition with little to no signs of wear. Capped by a green sapphire crystal Rolex never gave another model, the rim fires lime and emerald at every tilt. Set beneath it, a sunburst blue dial splits into a hundred blues, ice bright in daylight and near navy in a dim room. Wrapped around the wrist, a polished and brushed stainless steel bracelet plays gloss against matte and closes on a folding clasp with a hidden comfort extension.

Functions include hours, minutes, seconds. A screw down crown sits at three o’clock and handles all of it. Unscrew it counter clockwise, wind roughly thirty turns to wake the movement after a rest, then pull to the second position where the movement hacks so you can land the exact second. Push it back and screw it down to seal 100 meters of water resistance. Inside runs Calibre 3131, self winding with a 48 hour power reserve, a soft iron cage shielding the works, and a blue Parachrom hairspring that laughs at magnets.

Comes as a full set, double boxed with warranty card, card holder, manual booklet, white hang tag, and green Superlative Chronometer seal tag.

Rarely does a brand this restrained build something this playful, then walk away for good. Whoever lands it owns the Rolex that starts conversations instead of confirming them. Some watches wait to be found, and this one has waited long enough.
