[Originality Verified] - Authentic Serviced
The watch appears to be original and period-correct in its main configuration. Based on my assessment, the crown and hands appear to be later Rolex service parts, while the case and caseback, dial, and movement appear original.

This is a classic non-date Oyster, appreciated for its clean symmetry. Compared with Oysterdate models such as Ref. 6694, the case is slimmer (around 10mm) and wears more dressy. The larger 6mm crown is also a distinctive detail. This piece stands out for its clean dial, sharp hands, and well-balanced case proportions.

Not refinished, not repainted, with no clear signs of redial.
