The Geochron, a unique timepiece with a rich history, has gained popularity among enthusiasts. Founded in 1976, the company has produced only 30,000 mechanical models, making it a rare and exclusive item. With improved internal mechanisms and a wide range of analog and digital offerings, the Geochron appeals to cartophiles and map-data devotees. The brand's evolution into digital products, such as the Geochron Digital Atlas 2 4K, has made it more accessible to a broader audience.
