Zach Norris of Phoenix entered a Goodwill to buy a golf equipment carrier. On his way out, he rummaged through the used watch bin and found a watch with "LeCoultre Deep Sea Alarm" on the dial, priced at $5.99.
From Hodinkee:
Zach knew the LeCoultre name and knew the watch was made by Jaeger-LeCoultre and probably was worth far more than the $5.99 price, but he didn't realize it was a vintage LeCoultre Deep Sea Alarm from circa 1959 worth over $35,000. According to the price tag, the watch had been put out for sale the previous day, January 16, and although Zach had left empty-handed in terms of golf carts, Zach left the 43rd Avenue and Thunderbird Road store with something far better.
