This is a fantastic and collectible Rolex Day-Date Reference 18238 with an Adventurine stone dial. Adventurine is a form of quartz, characterized by its translucency and the presence of mineral inclusions that give a shimmering or glistening effect termed aventurescence. If you look closely at this original dial, you can see the sparkle in it. The case of this watch is very strong and possibly unpolished. The original 18kt yellow gold Presidential bracelet is also in exceptional condition with barely any stretch. This watch is powered by a caliber 3155 automatic movement. This watch looks like it is brand new. You can tell it was not worn much and was probably in someone drawer for many many years.
