Citizen's analog/digital combination watch, "Crystron LC Chronograph Dual Time."
It is the originator of the model commonly called "DIGI-ANA".
Model number: 41-9010
It was a very popular model at the time, so I think many people remember it.
However, considering the number of pieces, there are not many in good condition (usually either analog or liquid crystal is bad), and I sometimes see dead stock items at online auctions, but they are too expensive to buy.

The model with a black dial is the most popular, but I got a model with a white dial.

This model surprisingly does not have an alarm function (sound).
Also, it does not come with a light (bean ball).

Even back then, only a minority of people used alarms on their watches, and even with modern EL backlights, miniature watches had so little power that it was almost impossible to read the time in the dark.
If we take a closer look at the functions of digital watches, we may be able to get by without these two.
