Orange lightning bolt seconds hand sweeping a glossy black dial is the calling card of the Rolex built to resist magnetism for scientists and engineers. Rolex pulled this clear crystal black version from its lineup years ago, so no boutique can order you one today. Almost no other Rolex sport watch wears any orange, which makes it a quiet standout.

Presents itself in mint condition with little to no signs of wear. Glossy black lacquer gives the dial real depth and a clean face with no date crowding it. Orange steals the show on the lightning bolt seconds hand and the MILGAUSS script, a splash of color you will not find on another Rolex sport watch. Polished bezel against brushed and polished steel lets the case turn stealthy or bright as your wrist moves.

Functions include hours, minutes, and seconds, with no date to set. Unscrew the Twinlock crown at 3 o’clock and turn it in the first position to hand-wind the caliber 3131. Pull it out fully and the seconds hand freezes for to-the-second accuracy, then set the time, push the crown home, and screw it down to lock in 100m of water resistance. Self-winding does the rest on the wrist, with roughly 48 hours of reserve when you set it down.

Comes as a full set, double-boxed with a watch pillow, warranty card, warranty wallet, user manual, and red and green hang tags.

Made for lab work yet loved by collectors who want a Rolex nobody else is wearing, this one suits anyone after a watch with a sense of humor. You get the orange bolt and stealthy black dial on a model Rolex has already retired from its catalog. Message us to claim it before it sweeps onto another wrist.
