A parody of the brand Swatch, Kronos is depicted as a Swiss watch maker established in 1809. While only Kronos watches are advertised in GTA San Andreas and GTA Liberty City Stories, Kronos clocks and other timepieces were introduced in GTA Vice City Stories, appearing in Kronos' only store in Vice City in GTA III Era, located in Downtown Vice City; their logo can also be seen on Mules in GTA Vice City Stories. Kronos promotes its products in GTA IV with the slogan "The End of Time".
The company has two known watches that are advertised in GTA IV: the "Kronos Twatch" (a rhyme of the Swatch name, and also a combination of "twat" and "watch") and "The Gigante". In addition, a fully functional Kronos wall clock may be found in GTA IV at the South Bohan Safehouse, as well as various other interiors such as Oleg Minkov's apartment.
- The "Kronos" name is likely to be a derivative of "χρόνος" (chrónos), an ancient Greek term for time.
