Since 1989, the Promaster has been a diver dedicated to performance: functionality, durability and safety are its main features. Compliant with ISO standards, this new version, the Promaster Eco-Drive Diver 200m, is water-resistant to 200 metres thanks to its screw-down crown, back and pushpieces. It is equipped with a unidirectional rotating bezel for calculating diving times. A high-functioning sports watch, it uses Eco-Drive technology that recharges with light: once fully charged, it lasts for 7 months and has an alarm indicating the amount of energy remaining. The dial guarantees excellent readability in all light conditions, thanks to the luminescent treatment of the hands and indexes.
