Circula says it was founded in 1955 by Heinz Huber in Pforzheim, Germany. The site describes the company as a family business and says it is now run by Cornelius Huber in the third generation. A 70th-anniversary page says the business was continued by Klaus-Dieter Huber between the founder and the current owner, and the brand states that it has been developing and producing mechanical tool watches since 1955.
The site documents several specific production and product details. Circula says its watches have been assembled and tested in its workshop in Pforzheim since 1955, that each movement is regulated by hand, and that every watch is tested for water resistance before leaving the workshop. The site also says Swiss Sellita movements are checked again by its watchmakers before installation. For the SuperSport, Circula says the model has a real super compressor function and was developed with more than 4,500 votes from the watch community.
Collections documented on the site include AquaSport II, SuperSport, DiveSport Titanium, ProSea, ProTrail, and AquaSport GMT. Circula describes the AquaSport II as drawing on its diving watches from the 1970s. It describes the ProTrail as a modern German field watch, the ProSea as a dive watch based on the ProTrail's design language, and the AquaSport GMT as part of its dive watch range. The 70th-anniversary pages also document limited AquaSport II editions of 70 pieces, including the Original LE and Mother of Pearl LE.
Circula is based in the Pforzheim area in Germany, and its site ties the brand's assembly and testing work to its workshop there. The retailer page says the company has specialized in direct sales and works with only a few exclusive retail partners. The same page lists an address in 75172 Pforzheim, while product pages identify Circula Uhren GmbH at Poststr. 38, 75210 Keltern.
