When it comes to watch design, the smallest details can make the biggest difference — and double anti-reflective (AR) coating is one of those often-overlooked features that elevates a timepiece from good to exceptional.
Double AR refers to the application of anti-reflective coating on both the inner and outer surfaces of a sapphire crystal. This reduces glare to an absolute minimum and creates the illusion that there’s no glass at all between your eyes and the dial. The result is unmatched legibility, stunning clarity, and a sleek, high-end aesthetic that draws collectors in at first glance.
While many brands were slow to adopt this technology — often citing scratch-resistance concerns — DEEP was one of the first companies to embrace double AR as a key selling point. Long before it became an industry trend, DEEP recognized that serious watch enthusiasts valued crystal clarity over all else. By integrating this coating into their sapphire crystals early on, DEEP positioned itself as a forward-thinking brand that prioritized function, form, and visibility in equal measure.
Today, double AR remains one of the most requested features by collectors who demand the best — and DEEP continues to deliver it as standard. It's not just a coating; it’s a commitment to quality and a legacy of innovation.
