Mason Maressa saved $3,500 while working part‑time at a high school, deciding to purchase a vintage Rolex Air‑King instead of a car. The Air‑King arrived a few days later, and Maressa listed it online, closing the sale for $4,000 and pocketing a $500 margin.
Reinvesting the modest profit, he began buying more watches, learning to spot authentic pieces, to gauge condition, and to price items competitively. Each transaction deepened his understanding of the pre‑owned luxury market, turning hobby into a disciplined trade.
In January 2025, Maressa launched Clocked In, a brick‑and‑mortar shop at 601 S Beacon Blvd, Suite 103 in Grand Haven. The store operates by appointment only, offering customers the chance to touch and compare models such as Rolex, Omega, and Tudor before buying.
Clocked In stresses that building customer trust is essential in a market where identical models can differ wildly in condition. The firm advertises its focus on authentication, quality, and service, positioning itself as a reliable dealer for both seasoned collectors and first‑time buyers.
Five years after his first Rolex purchase, Maressa reports that Clocked In has achieved over $10 million in cumulative sales. The company now serves collectors across West Michigan and beyond, and its next milestone will be expanding its footprint to new markets.
