Casio SA-54 slim digital watch

Today I'm back to another of my vintage Casio LCD watches.

This model is the SA-54 and is the second of the SA- watches I've blogged (-the first being in June 2014). The SA watches seem to have first appeared in 1984, and I've seen quotes that this SA-54 model was released in that year. The SA- watches seem to share a slim design as a common design feature, and this SA-54 fits with that brief, being only about 4mm thick.

It has a standard 6 digit LCD panel, with smaller seconds and a narrow first digit. Inside is a Casio 145 quartz movement which is an alarm chronograph module. Overall, this gives the watch dual time, an timer modes as well as the alarm and chronograph, and these are marked just above the LCD display.

The back has the older design with the information engraved in a ring. It into has the basic information present, just saying the brand, model, movement number, and material (stainless steel back). There is also a serial number, and that this watch was made in Japan.

Casio SA-500G LCD watch

Today, I've got a mystery Casio to blog, as I've not found a web link to another that's the same.

This Casio model is the SA-500G. So far, I've found lots from the SA series, including the SA-50 and SA-50G, but there is no sign of the SA-500.

From what I've found, the SA series came out around 1984, although one site suggested 1986. They all were similar LCD models and shared the use of a Japanese Casio 145 module. The case design was also similar across the range, and the models were pretty thin for the time (although not compared to the film watch Pela).

The LCD panel has one line of digits (5 1/2 and the seconds are smaller), and holding one of the buttons reveals the day and date. The other modes for the watch are alarm, dual time, timer, and chronograph. There is no separate button for setting, with the setting option at the end when you cycle through the modes.

As well as the model number, there is also a number on the face which is 901A1-116. The strap is a Casio gold coated model with a part number of B-453N.
