Retail and secondary market pricing for Rolex GMT-Master:

Retail: USD 2000 to USD 15000, varying by year.

Secondary: Pre-owned prices range from 80-110% of retail depending on service history.

Service every 5-10 years to ensure movement accuracy. Avoid magnetic fields and extreme temperatures to maintain timekeeping precision.

Rinse with fresh water after saltwater exposure and dry with a soft cloth. Avoid chemicals and cosmetics to preserve the case finish.
