Named after the emperor who transformed an empire, Constantine embodies the power of transition and the clarity of vision required to lead it. It is a timepiece for men who stand between worlds, honoring tradition while shaping what comes next. The two-tone composition reflects just that.

The polished hardened steel case represents structure, discipline, and permanence. The champagne-colored dial introduces warmth, perspective, and forward momentum. Together, they express balance, the tension between strength and refinement, legacy and evolution. Transition guided by vision.

Its rectangular 28 × 40 mm proportions reflect classical order, while the ultra-slim 7 mm profile ensures effortless elegance. The polished steel frame creates sharp architectural lines, encasing a dial that radiates subtle depth through its geometric texture. Roman numerals pay tribute to imperial heritage, while blued hands cut across the champagne surface with confident precision.

Sapphire crystal with anti-reflective coating preserves clarity in every light. The arched, screw-down sealed case back reinforces durability, and 5 ATM water resistance ensures resilience for daily life, even suitable for snorkeling.

Inside, the Swiss ETA 901.001 quartz movement beats with unwavering reliability. Operating at 32,000 vibrations per hour, it delivers an accuracy of ±3 minutes per year and an exceptional 11-year battery life. Hours and minutes only, a deliberate commitment to focus and direction.

Each Constantine carries a unique serial number, marking its individuality within a disciplined lineage.

Constantine represents more than contrast in color. It represents the courage to evolve without losing foundation. A rectangular watch for men who lead change, with structure, with vision, and with purpose.
