In the early 1960’s SEA-GULL set out to develop the first chronographs for the Chinese fighter pilots. By 1966 development was successfully completed and 1400 watches in total were delivered to the high-commands of China’s air force and navy. SEA-GULL’s current series of chronographs represents an upgrade and modernization of the first model, but even after significant improvements have been made in materials, craftsmanship and overall quality, both the movements and the designs remain true to the traditional manual winding column wheel chronographs. This series of chronographs with different functionalities are made in steel with scratch resistant sapphire and have a transparent back through which the classical beautiful mechanical column wheel chronograph movement can be admired. A black high-quality leather strap with a folding buckle in steel completes these stylish chronographs. A seductive dress watch as well as a reliable every-day time keeper.
