The AMW320 is one of the longest running analog / digital watches for Casio. It was featured in many movies as well. It went through couple of module changes through its history: original was 358 (1 button left / 1 button right); then 1374 (2 buttons on left); the recent ones are 2701 (also 2 buttons on left, not sure what other difference). Even for the newest module version, some of the models (color & face design variations) are pretty hard to find. In addition, some of the related products, like the solar AMWS320 and solar atomic WVA320, are very hard to be found for sale also. Looks like Casio either stopped or cut down on the production. Or may be there are a lot of collectors out there for them. Also the owners probably just like them too much and not easily let them go.
The AMW320 is no doubt a classic. But it does lack digital functionality the current Casio's have. Such as it has no timer, and no light function at night. Recently I came across a video (see below), and realized how small and simple the module is inside. On one hand, its simplicity makes it easy to maintain and even to mod (like to re-lume). On the other hand, it does look cheap inside and makes me wonder whether if it really worth its value only based on its exterior design.
So I like hear the opinions from the owners.
1. How good is the original lume?
2. How frequently you need to change battery?
3. After seeing how simple the inside is, do you regret your choice?
Any other input welcome. Non-owner welcome to chime in too, if you have good inputs.
