Seagull Extraordinary Series Moon Phase Dress Watch 40mm

Owners widely praise the Seagull Extraordinary Series Moon Phase Dress Watch 40mm for its classy, elegant design and excellent value, with many calling it a potential favorite dress watch. The 12.7mm thickness is considered well-proportioned to the 40mm case. The moonphase complication is a highlight, though owners note it requires manual adjustment by setting the date and moon position one day prior and is considered a pain to set. Some find the dial text crowded at the 6 o'clock position. Overall, owners rate the Seagull Extraordinary Series Moon Phase Dress Watch 40mm highly for its beautiful dial and true moonphase complication at its price point.
