G'day,
GP did a lot of "stylish" pieces in the 1960´s and 1970´s, most of them reflecting current design trends then.
Almost all of them are using outsourced movements and used to list for $50 to $300, so it´s been a different ballgame of what the brand is doing today. Only few models came with dedicated model names, so it´s pretty much one of many (hundreds) of models during those decades.
The value is reflected by what you paid for it, which is probably not comparable to a current production piece in any way.
Cheers,
Peter
