Casio Ana-Digi Alarm Chronograph AQ-440

A while ago, I posted about a very unusual Casio called the AQ-441G and didn't know much about it, apart from the fact that it was extremely rare.

Today, I'm posting about the predecessor the AQ-440.

This watch uses the same 307 module as the AQ-441, but was released a year or two earlier. This model came out in around 1985 and is an ana-digi model with an LCD and a rotating disc display. The discs cover the top two thirds of the face with a single line LCD below.

For the analogue display, there are three risks which rotate clockwise, with the hours on the outside, and seconds on the inside. Two thirds of the discs are visible, but the lowest 1/6 is behind a shaded window.

The LCD panel has a 6 digit display, and is used to show either time, date, or the other modes which are chronograph, alarm, and dual time.

This model has a silver case with an angular appearance, and a strap design which is matched to the case (part number B-762N). The AQ-441G had a more rounded case, and much less of the discs were visible, but the insides were the same. I've seen variants of this watch in gold, or with a black set of discs.

A comment on my last post said that the AQ-441 was rare even after a couple of years from manufacture, and that it was one of the most expensive watches Casio made at the time. I'd guess that the same applies here as there seems to be a similar number of hits on the Web.
