Citizen Promaster SST Eco-Drive Watch

The Citizen Split Second Timer, or “SST” for short, is a feature-laden timepiece with a sporty racing-inspired look. Perhaps its most important feature is the 1/1000th-second chronograph and the ability to recall up to 20 previous times, which is excellent for timing laps in any sport. Furthermore, it’s equipped with a world timer (with 31 different time zones), a 99-minute countdown timer, an average speed calculator, and a date tracker. Made of stainless steel and water resistant to 200 meters, the Promaster SST is protected by way of a sapphire crystal. As with every other watch in the collection, it’s powered by an Eco-Drive movement that never requires a battery. 

The Citizen name is more than just that—it’s a promise to citizens around the world to create quality, accessible timepieces that drive our planet forward. Founded in 1918, Citizen has been an innovator in the watchmaking industry for more than a century. The oil crisis of 1973 proved to be a turning point for the brand. As global awareness of alternative sources of clean energy spiked, Citizen rose to the challenge and created Eco-Drive: a solar-quartz movement powered entirely by light, eliminating the need to replace harmful watch batteries. Today, Eco-Drive is at the heart of almost all Citizen watches, carefully tracking the time and lighting the way for a better world.
