Casio MDV-107 Duro Watch

The Casio MDV-107, often referred to as the 'Duro' without the marlin logo for the international market, is a staple of Casio's affordable dive-style watch collection. The brand Casio was founded in Tokyo, Japan, in 1946 by Tadao Kashio. While the brand is synonymous with Japanese innovation and engineering excellence, most of its entry-level and mid-range timepieces, including the MDV-107 series, are manufactured in China to maintain competitive pricing while adhering to Casio's strict quality control standards.

Casio remains an independent Japanese multinational electronics company. It is governed by Casio Computer Co., Ltd., headquartered in Shibuya, Tokyo. The company has historically been a pioneer in the digital watch industry and continues to manage its portfolio globally through various regional subsidiaries. The MDV-107 remains one of the most respected budget timepieces in the horology world due to its reliable quartz movement and 200-meter water resistance.
