Citizen Promaster Eco-Drive Diver 200m “Pepsi”

Reference: BN0159-18X / Caliber E168

History

The Citizen Promaster line was introduced in 1989 as Citizen’s dedicated professional sports and tool-watch division. The collection quickly became famous among divers, pilots, and adventurers because Citizen focused on practical reliability instead of luxury gimmicks.

The BN0159 series became one of the most popular modern Promaster divers thanks to its rugged ISO-certified construction, comfortable wearability, and Eco-Drive solar technology. This particular Pepsi bezel variant combines classic vintage diver aesthetics with modern quartz accuracy and solar charging convenience.

Unlike traditional automatic dive watches, the Eco-Drive system converts any light source into energy, eliminating battery changes and making the watch extremely practical for daily wear and travel.

Collectors appreciate the BN0159 because it delivers true professional dive-watch specifications at an affordable price point while maintaining the classic look of vintage Japanese divers from the 1970s and 1980s.

Its 44mm stainless steel case offers strong wrist presence while remaining comfortable due to the short lug design and lightweight Eco-Drive quartz movement.
