About This Watch
The Rotary GS03900/21 Moonphase is an elegant dress watch that blends classic styling with practical functionality. Its tonneau-shaped stainless steel case, silver sunburst dial, and Roman numeral indices create a timeless, sophisticated aesthetic, while the moonphase indicator and day/date subdials add refined complexity.
Powered by a precise quartz movement with a new battery installed, this watch delivers accuracy and reliability suitable for both everyday wear and formal occasions. The blue hands and multifunction layout offer a stylish touch that elevates this piece within Rotary’s dress collection.
Founded in La Chaux-de-Fonds in 1895, Rotary has long been known for producing dependable, beautifully designed watches — and this moonphase model carries that tradition forward with charm and quality.
