Whether on land, sea, or air, no matter time or circumstance, PROMASTER has backed professionals in their work with safe, consistent support for over 30 years.
Enabling this history is over 100 years of Citizen craftsmanship DNA

1989 saw the arrival of the PROMASTER brand for land, sea and air professionals. Prior to that, Citizen had developed a variety of watch series embodying its “Sporté” and “Citizen Sporting Life” brand messages. In fact, the logo mark for the new PROMASTER brand featured an arrow design, signifying the concepts “go higher” and “go deeper” from these earlier brands, and a text motif based on the letters SS (for “Sporting Spirit”) associated with them. Built to meet the demands of professionals active in challenging environments, PROMASTER specs are the culmination of Citizen’s century-long commitment to overcoming the challenges of watch development.
