SEA-GULL D304 Original Reissue 40mm

The SEA-GULL D304 Original Reissue draws inspiration from the historic Project 304 aviation chronograph, bringing its distinctive design into a 40 mm stainless steel case. A light champagne sunburst dial features the classic Flying Arrow emblem, faceted silver-tone markers, sword-shaped hands, and a red chronograph seconds hand. Powered by the hand-wound ST1901 column-wheel chronograph movement, it pairs traditional mechanics with a domed sapphire crystal. The solid caseback carries a nine-star motif and Tianjin Watch Factory detailing that honour its aviation heritage.
