The company seems to be known for their exaggeratedly large wrist watches.
The company can be seen advertising "BigTime" watches in various locations around the state. Although their store is inaccessible to the player, the player can see the watches on display in the windows.
The male GTA Online Protagonist can buy watches of the brand from any clothing store in Grand Theft Auto Online, while organizations can also store and sell looted Pendulus watches. Also in GTA Online, the player can apply a Pendulus livery to the Nero Custom.
The name Pendulus is a Latin word that translates roughly to "hanging", and a derivative of the English word "pendulous". The two "u" letters in the logo have two dots on them, which could represent nipples on two hanging breasts, an example of Rockstar Games sexual humor.
They share a building with TSLC and Tim Vapid and it is a replica of the main building at 9501 - 9519 Wilshire Boulevard which anchors Two Rodeo (aka Via Rodeo), where there is a Buccellati watch and jewelry store.
