In April of 1961, the Chinese Ministry of Light Industry tasked the former Tianjin Watch Factory to make a chronograph watch for the Chinese Air Force, mission code: 304. The mission was completed in 1963 and several thousand pieces of the D304 chronograph were handed over to Chinese Air Force.

This watch was launched in 2018, limited 5,500 pieces, marking the 55th year of the D304 watch since 1963. The identical design and the Chinese characters on the dial confirm the identity of this watch, and the 38 mm case diameter, the ivory white dial and the domed acrylic crystal adds up to the vintage feel of this watch.
