Tough and Popular Black G-Shock (AW590-1A) – Review and Compare

Review Summary

The physical dimensions of the watch are a good combination of form and function. The mineral crystal face is recessed nicely and protected well but still offers a clear view with a quick glance. Overall I’m very pleased with my purchase and would highly recommend this watch to anyone who genuinely appreciates Casio’s G-Shock line watches.

Casio G-Shock AW590-1A Review

5 out of 5 – Reviewed by Jamie

I spent some time researching every G-Shock offered by Casio and narrowed it down to the AW590-1A for several reasons.

• I prefer traditional battery over Tough Solar. I have read numerous negative reviews about the rechargable batteries giving out anywhere from 1-5 years and in the end are very difficult to replace.
• This watch uses a larger CR1220 battery which Casio estimates will last about 3 years and is easily replaceable.
• The AW590-1A uses round metal buttons, and not the cheaper rectangular plastic ones on some other G-Shocks, which can get “squeaky” and wear out.

Now on to the watch itself. You need to set the analog time separate from the digital, however they do sync up perfectly once both are set. The analog minute hand moves every 20 seconds and seems very refined.

The top led bar simply ticks off every 10 seconds while the left circle shows numeric seconds. The bottom circle shows whether certain functions are activated, like DST, alarm, snooze, hourly signal and split time in the stop watch function. The left circle does the most: in normal time mode it can be toggled to show month/date, day of the week or digital time. It has a nice resolution and also serves as the stopwatch and countdown timer.

World time is cool as only the left circle changes to show you the digital time in another time zone, while the analog stays in your home zone, allowing you to compare times instantly.

The watch has a whopping five separate alarms, one of which has a snooze function. I don’t find the need to have that many alarms but some may find it useful. Countdown and stopwatch are nothing special, pretty much what you expect.

There is also an Auto LED feature which I find an unnecessary battery drainer. Once enabled, a quick upward motion of the wrist automatically causes the light to come on. I found that you can quite often set the light off unintentionally. Luckily you can disable this feature.

The physical dimensions of the watch are a good combination of form and function. The mineral crystal face is recessed nicely and protected well but still offers a clear view with a quick glance.

Overall I’m very pleased with my purchase and would highly recommend this watch to anyone who genuinely appreciates Casio’s G-Shock line watches.
