Migraine GK275 by Swatch is a visually striking vintage Gent wristwatch released in 1998. The model is built around an optical-illusion concept, using black-and-white graphic elements that appear to shift and move as the watch is viewed from different angles.

The watch has a transparent plastic case measuring 34 mm / 1.34 in in diameter and 8.75 mm / 0.34 in thick. It is fitted with a plastic crystal and white plastic strap, powered by a Swiss quartz movement, and was originally rated to 3 bar / 30 m water resistance.

The strap is decorated with repeating black dot patterns that create a moving or vibrating optical effect. The dial continues this visual theme with a jagged black starburst composition, a red hour hand, and an unusual rotating minute disc marked by a small red point rather than a conventional minute hand.

Migraine reflects Swatch’s experimental late-1990s approach to graphic design, where the watch face and strap were often treated as a continuous visual composition. Its optical effects and unconventional time display make it one of the more unusual Gent models of the period.

A strong vintage collectible for admirers of Swatch, 1990s design, optical art, graphic watches, Swiss quartz watches, wearable design, and unusual vintage Swatch models.
