Batsknight GK331 is a vintage Swatch Gent Halloween Special released in 2000.

The watch uses Swatch’s classic Gent format with a plastic case measuring approximately 33–34 mm / 1.30–1.34 in in diameter. It is powered by a Swiss quartz movement and was originally rated to 3 bar / 30 m water resistance. Specialist listings consistently identify it as a 2000 Halloween release.

Its design centers on a dramatic nocturnal Halloween scene. The dial features a vampire beneath a full moon, surrounded by flying bats against a deep blue night-sky background. The dark blue and transparent plastic strap continues the bat imagery, allowing the entire watch to function as a single themed composition.

The watch also incorporates luminous details, giving parts of the design a glow-in-the-dark effect. This adds an extra visual dimension in low light and strengthens the model’s connection to Swatch’s playful Halloween Specials of the late 1990s and early 2000s.
