G'day,
the 4900-Series is a product range by Girard-Perregaux of the 1990´s; there may be a watch made in 2000 (which would be surprising given the low case numer), but most of these watches were made between 1995 and 1999.
All these bear a movement supplied by ETA and while it´s been changed by GP, many appreciate GP´s propietory movements over outsourced ones. The GP4900 range naturally was priced quite a bit lower than GP´s watches with GP´s own movements, hence it may not be truly comparable to current models. All in all, a nice range for everyday wear and well-trusted.
There some dozen older discussions on various models of the GP4900 range; i´d recommend to use the search function, as it may answer many questions.
Cheers,
Peter
