It has an alligator leather strap with the original 18k white gold Patek Philippe tang buckle, and a scratch resistant sapphire crystal. There are two crowns; the one at 2 o'clock winds the watch and adjusts the time, and the crown at 4 o'clock adjusts the sky, lunar orbit and moon phases. It has a screw down exhibition sapphire display case back, and the 43mm diameter solid three-body case, screwed gently curved lugs, and stepped concave bezel, are polished.

There are white gold perimeter Roman hour graduations, and there is an aperture for the moon phases. It has the orbit of the moon as well as the time of the meridian passage of Sirius and the Moon, which was designed by the Patek Philippe engineers who used sophisticated computerization to produce the single precise ratio out of 25 trillion ratio combinations. The accuracy is astounding: The lunar day is accurate to 0.05 seconds per day, 18.385 seconds per year, or 30 minutes and 38.5 seconds per century. The sidereal day is accurate to 0.088 seconds per sidereal day, 32,139 seconds per year, or 53 minutes and 33.9 seconds per century. The moon phase is accurate to 6.51 seconds per lunation.
