About the Rolex Datejust 178279 — No Cyclops Reference

Most Rolex Datejust references include the Cyclops lens — a small convex magnifier positioned at 3 o'clock on the crystal directly above the date window. The 178279 omits this entirely. A flat sapphire crystal covers the full dial surface without interruption. For buyers who want a Datejust with a cleaner, unbroken crystal face, the 178279 is the reference to know.

The 178279 pairs the no-Cyclops crystal with an 18k white gold case and smooth white gold bezel. Dial options include white, silver, black, champagne, and mother-of-pearl — many set with diamond hour markers. It wears on either the Rolex Jubilee or Oyster bracelet in 18k white gold. The caliber 2235 automatic movement powers the watch with approximately 48 hours of power reserve.

Pre-owned 178279 examples hold their value well. This reference shares the same movement and case architecture as the 178274 diamond-bezel variant but offers a more restrained aesthetic. Both are strong used Rolex Datejust purchases for buyers entering the mid-size Datejust market.
