This model is a bit of an odd bird. The module 140 is similar to the 110 (F-300, F-500) and the watch dates to the early 80's like they do. It's got the stainless steel shell over resin body construction that Casio did for a few models during that time period but, strangely enough, the watch doesn't have 'STAINLESS STEEL TOP' on the caseback like those others do.
