Condition Notes
The watch appears to be in excellent to near-mint condition, showing crisp case chamfers, clean brushed surfaces, an unblemished crystal, and sharp bezel markings. The bracelet shows no visible stretch, and the overall aesthetic preserves its factory finish.
Value Estimate
Retail MSRP is approximately $3,900 to $4,100 USD on bracelet. Secondary market and pre-owned values generally range from $3,100 to $3,700 USD depending on condition, completeness of box and papers, and age.
Care & Maintenance
Recommended full mechanical service every 5 to 10 years by an authorized service center. Water resistance pressure testing should be performed annually if used for swimming. Rinse with fresh water after exposure to saltwater, and avoid strong magnetic fields.

Interesting Facts
The Black Bay Fifty-Eight was created in direct response to collector demand for a smaller, thinner Black Bay that better matched the proportions of vintage references from the 1950s. The 'big crown' and riveted bracelet design are direct homages to historical Tudor dive watches used by naval forces.
