Fitted in an awe-inspiring 18K yellow gold case, the current wristwatch stands out with its wonderful “Mark I” white porcelain dial. One of the most desired configurations today, a number of unique characteristics contribute to the fervent following towards the “Mark 1” design. Most remarkably, the “Cosmograph” lettering is separated from the other four lines of text “Rolex, Oyster Perpetual, Superlative Chronometer, Officially Certified”, contributing to its “Floating Cosmograph” moniker. In addition, the subsidiary dial above the six o'clock features an inverted “6" which looks like a “9”. It is also a tritium dial and is labeled as "T SWISS T" at six o'clock.

Adding another element of desirability, the “Mark 1” dial of the present watch is made of fine white porcelain, which amply exudes an awe-striking luster unmissable by its beholders. Today, the porcelain dial with serial R has become hugely popular amongst watch collectors due to its imposing look and rarity. This watch also features a period-correct 18K yellow gold bezel which was marked till the unit of 200. Being from the very first R-series, the present example is accompanied by a blank guarantee punched with matching numbers, box, in addition to other accessories.
