CONVTROL9  Rolex Datejust. Reference 16238. Watch measures 36mm and is made from yellow gold. Automatic Rolex movement caliber 3125 which is COSC certified. It has 31 jewels and has a power reserve of approx. 40 hours. Sapphire crystal on the front and a closed case back. Waterproof 10ATM or 100 meters. Functions are hours, minutes, sweep seconds and (magnified) date. This watch is fitted with a NON-original black leather strap with the original yellow gold plated Rolex pin buckle. The dial is made from black onyx and is without any hour markers or indexes which is very rare. The crown is screw-in. Uncharacteristically for us this watch comes without any box  and papers but the watch is in great condition and runs beautifully. Very rare to find! SOLD
