It represents the final generation of the 26mm Oyster Perpetual before the brand moved toward larger case sizes.

Origin & Provenance
Swiss Made. Manufactured in Geneva and Bienne, Switzerland. In-house movement and metallurgy.
Age Estimate
Circa 2007–2014. The engraved rehaut (inner ring with 'ROLEX ROLEX') and the 176xxx reference series indicate this mid-modern production window.
Cultural Significance
The Oyster Perpetual is the direct descendant of the original 1926 Oyster, the first waterproof wristwatch in the world. It is the purist's Rolex, omitting the date for perfect symmetry.
Condition Notes
Based on the image, the watch appears to be in 'Good' to 'Very Good' condition. There is visible softening of the lug edges suggesting previous polishing, and typical micro-scratches on the polished gold center links.
Value Estimate
$4,500 - $6,000 USD. Prices are influenced significantly by the presence of original box/papers and the number of removable links remaining in the gold/steel bracelet.
Care & Maintenance
Service every 10 years recommended. Ensure the crown is fully screwed down before any water exposure. Clean the bracelet with a soft cloth and mild soap to prevent 'stretch' caused by dirt friction.
