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, located in Downtown; also GTA Vice City Stories, their logo can also be seen on Mules driving around. Kronos promotes its products with the slogan "The End of Time".
The company has two known watches that are advertised in GTA IV and GTA V: the "Kronos Twatch" (a reference to the Swatch Delirium) 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 has it's own store in Legion Square, Los Santos.
- The "Kronos" name is likely to be a derivative of "χρόνος" (chrónos), an ancient Greek term for time.
