yep, Girard Perregaux....although they made their inhouse drivers watch for some reason they also opted to go for the cheap generic modules and even used the very same cases used with other low-end brands. both GP's from the link above I once had but branded as Helbros. the only difference with the rectangular one is the position of the button.
