Introduced in 1953 on the Datejust model, the Cyclops was designed to increase the visibility of the watch's date window and make it easier to read. The magnification lens and crystal were originally fashioned out of one piece of plexiglass, but in the 1970s, Rolex began using sapphire for their crystals and subsequently began making the Cyclops out of sapphire as well, affixing it onto the crystal. Today's lenses feature an anti-reflective coating that helps reduce the glare that comes from the light being refracted off it.

If you prefer a timepiece with no magnification lens, there are several Rolex models that don't come with one. The Cosmograph Daytona and Yacht-Master II models don't have a date function, so those would be good choices. The Submariner has a model configuration with no date and the Explorer I and Milgauss models don't come with one either. There are Oyster Perpetual models that are available without the date as well. However, if you are set on a Rolex but would find the date function useful, there are two models that you can look at that feature a date aperture but no Cyclops lens.

The two Rolex models that feature a date function but no Cyclops are the Sea-Dweller 4000 and the Deepsea. Shown in the close up photo above, the Sea-Dweller 4000 is the closest you can get to a Submariner Date with no magnification lens. It has the same size case as the Sub, 40mm, and a 60-minute graduated bezel with a Cerachrom insert. Aside from that, the Deepsea is the only other model that they currently offer with a date function but no Cyclops. Available with either a black dial or the D-Blue dial that features a blue gradient design, it is larger than the Sea-Dweller 4000, with a 44mm case and a depth rating of 3,900 meters.
