Rolex Explorer II Polar 16550 'Rail Dial' 40MM 1987

The stainless steel case remains in great vintage condition, displaying only light hairlines around the sides consistent with careful wear over time. The edges retain good definition and the case has not been subject to heavy polishing, preserving its original profile.

The standout Polar dial is in excellent condition, having developed an attractive and even cream patina across the hour markers that adds depth and warmth to the watch’s overall character. The rare ‘Rail Dial’ printing is sharp and intact.

The Mercedes hands are also in great condition, showing light oxidation that harmonises with the creamy patina of the lume, creating a cohesive vintage aesthetic.

Overall, this is a well-preserved example of the transitional Explorer II reference 16550, combining its distinctive dial layout with the highly desirable cream-toned patina. As this piece is now over 30 years old, it should be treated as a vintage timepiece and not worn while swimming, even though the model was originally designed as a tool watch.
