Pre-owned Rolex Day-Date 36 ref 18238 (1990) originally came to market back in the late 1980s and represents an important era in the collection, right before it shifted to the first 6-digit generation. With this model, Rolex upgraded the famed Rolex Presidential to the caliber 3155, which now had a Quickset for both the date and day of the week. Furthermore, it sports a scratch-resistant sapphire crystal, laying the groundwork for the DD36 as we know it today. Still, despite newer versions of the watch, collectors continue to reach for this model. It’s modern yet still retains the classic brushed lugs without skimping on the wrist flex many expect from a full gold Rolex. Buy it today in excellent secondhand condition.
