About the Rolex Explorer II Ref. 16550

The Rolex Explorer II reference 16550 represents a transitional period for the model, bridging the gap between the vintage four-digit references and the modern five-digit iterations. It introduced significant updates while retaining some classic elements. This reference is notable for being the first Explorer II to feature a sapphire crystal and a quickset date function, enhancing its practicality and durability compared to its predecessors. It also marked the introduction of the caliber 3085 movement.

This reference features a 40 mm stainless steel case, characteristic of Rolex's robust sports watches. It is equipped with the automatic caliber 3085, which provides a power reserve of approximately 42 hours. The watch maintains a water resistance of 100 meters and is protected by a sapphire crystal, a key upgrade from the acrylic crystals found on earlier Explorer II models. The fixed 24-hour graduated bezel is also made of stainless steel.

For collectors, the 16550 is particularly appealing due to its transitional nature and the presence of both white and black dial variants. The white dial versions are sometimes referred to as 'cream dials' due to a tendency for the lacquer to age into a creamy patina, making these examples highly sought after. This reference offers a blend of vintage aesthetics with modern technical advancements, making it a significant piece in the Explorer II lineage.

Out of curiosity has the dial reached peak patina or would it go darker over time?
