The innovative mechanical watch brand "Custos" was created in 2005 by young businessman Sassoon Sirmaces and designer Antonio Terranova. Custos, which means “guardian deity” in Latin, protects the essence of Swiss watchmaking traditions, but is based on its own philosophy of “sporty”, “elegant” and “high-tech”. Kustos' technology is based on four unique values: performance, efficiency, elegance and rarity. The strong desire to combine these four values in all processes and to add elegance and rarity to each part creates a high level of technology.
