About CiRCULA
CiRCULA is a family-owned company based in Pforzheim, one of the most traditional centers of German watchmaking. Since 1955, the company has been developing and producing mechanical tool watches – dive, pilot, field and steel sports watches – with a clear, modern design. The assembly and final inspection of every watch takes place in the company's own manufacture in Pforzheim: watchmakers regulate each movement and test the water resistance of each case before the watch leaves the company. The cases are made of stainless steel and are hand-blasted and hardened; other materials include ceramic for bezel inserts, sapphire crystal and mother-of-pearl for limited editions. Distribution is via direct sales (e-commerce) with climate-neutral worldwide shipping.
