The 39mm-wide Rolex Cellini case is an Oyster, but it still has a screw-down crown and is water-resistant to 50m. Over the dial is a double-domed, AR-coated sapphire crystal. Inside the watch is an in-house-made “Superlative Chronometer Certified” Rolex automatic caliber 3195 movement with 48 hours of power reserve operating at 4Hz. Complications include the time, moon phase, and a pointer-style date which uses a blued steel (also something you don’t see every day at today’s Rolex) hand. This latter element is another item (like the moon phase disc) that is not likely produced in high quantities.
Rolex redesigned and re-introduced the Cellini collection of dress watches in 2014. Since then, the brand has launched an almost unprecedented collection of four different movements for the formal watch family. That includes a time-only Rolex Cellini, one with a date dial, the Rolex Cellini Dual Time, and for 2017, the Rolex Cellini Moonphase. For the longest time, Rolex was keen to White Rolex Cellini Moonphase Automatic 50535 produce high-quality albeit simple watch movements. The reason for this being that they wanted to reduce possible problems in the movements for consumers while also increasing production efficiency.
By far the most interesting detail on the Rolex Cellini Moonphase watch dial is the moon phase indicator disc itself. This is a decidedly “non-mass-produced” object made using an enameling technique as well as having a moon disc produced from a piece of meteorite. Those replica rolex watches familiar with moon phase indicators will immediately see that Rolex’s interpretation of the moon phase complication is unique. Rolex explained that they wanted their moon phase indicating watch to be a bit different from others out there.
Accurate to 122 years when initially set, the moon phase indicator uses an indicator arrow below the hands and the disc itself turns. Typically, there would be a frame over the disc to help offer a more visual indication of the moon’s shape in the sky. Here, however, there is a solid meteorite moon opposite a totally dark moon. The disc moves in one direction, and the idea, I believe, is that both discs represent the moon as the disc makes a full rotation
