The Certina DS-1 Big Date Powermatic 80 is a statement of Swiss style and precision. Designed for men who value elegance and performance, this automatic watch combines refined finishes with cutting-edge technology. Its all-black PVD coating gives it a modern and sophisticated character, ideal for both urban environments and formal occasions.

Inside, beats the Powermatic 80.651 movement, which offers an 80-hour power reserve and uses a Nivachron™ hairspring, highly resistant to magnetic fields and temperature variations. The model's main highlight is its Big Date window at 6 o'clock, which combines functionality and aesthetics in perfect balance.
