Citizen Promaster - History and Development

Origins of the Promaster Series

The Citizen Promaster series was introduced in 1989 and has since become one of Citizen's most well-known and respected collections. Designed specifically for professional users and adventurers, this series offers a wide range of watches designed for extreme conditions and demanding environments. The Promaster series includes watches for use on land, sea and air, and has made a name for itself over the years through continuous innovation and technological advancements.

Early developments

From the very beginning, the focus of the Promaster series has been on providing robust and reliable watches that meet the extreme demands of divers, mountaineers and pilots. Citizen used its extensive watchmaking experience and innovative technologies to create watches that excel in both functionality and durability. An early example of this is the Promaster Aqualand, the first diver's watch with an integrated electronic depth gauge.

Citizen Promaster Technology and Innovations

Eco-Drive Technology

An outstanding feature of many Promaster watches is Citizen's Eco-Drive technology. This technology allows the watches to charge themselves through light - be it natural or artificial - eliminating the need for battery changes. The Eco-Drive technology is environmentally friendly and ensures that the watches function reliably even under extreme conditions.

Radio control and GPS

Some Promaster models are equipped with radio control and GPS, which allows for precise timekeeping and automatic adjustment to different time zones. These features are especially useful for pilots and frequent travelers, as they increase the accuracy and usability of the watches.

Robust materials

The Promaster watches are made of high-quality and robust materials that can withstand extreme conditions. These include stainless steel, titanium and special plastics that are resistant to corrosion, shocks and extreme temperatures. Some models also use Super Titanium, a titanium alloy developed by Citizen that is even more resistant and lighter than traditional titanium. Citizen Promaster for Divers
