Disclaimer: This isn’t gonna be a techy or wordy watch review. It’ll be brief and hopefully convey why the Casio GBX100 has all the features you want in a tide watch without much bloat, at a reasonable cost.

I’ve had a couple of Casio G-Shock tide watches in the past. They were super durable, never broke, and had batteries that lasted for years. But the tide graph was limited, basically just telling you if the tide was rising or falling, and the watch band was a little stiff.

My most recent watch, the G-Lide GLX150 had the standard LED display, which made it hard to view the screen if tilted at an angle.

The curve of the tide graph, shown here, never changes, what does change is the highlighted section telling you were you are in the tidal swing. I couldn’t tell if the tidal swing was steep or shallow.

The G-Lide GBX100 came out in 2020 and was the most advanced G-Shock tide watch to date. The resin and stainless steel case is very light yet durable and sports the retro look of the 80s. The buttons are on the side and recessed, which makes them less likely to accidentally depressed, and the strap is very supple and comfortable. The strap’s drainage slits allow your wrist to breathe and stay dry, and has two metal prongs to hold the strap to your wrist. It’s water resistant to 200 meters.

The display uses a high-definition LCD which makes it viewable in bright conditions, and at an angle. If you need to view in low light, there is an LED backlight available at a push of a button. Very easy to make out the time and date, even with old eyes.

There are 3 screens that will aid your fishing.

Sun rise and sun set times with moon age.

(Sun is rising at 7:01 am, setting at 5:52 pm, and the moon age is 10.6 which is 4 days before the Full Moon)

The day’s highest tide and lowest tide.

(High tide at 2:21 am @ 2.00 ft, low tide at 6:54 pm @ -0.01 ft)

View at a glance of date, time, sun rise, sun set, moon age, where you are in the tidal flow, and next high or low tide.

(In this example, the tide is falling to a low of -0.01 ft at 6:54 pm)

This is the most useful screen.

The watch is technically a smart watch but faulty. It’s klunky to pair and use the fitness features with a smart phone so I opted to configure the watch manually.

I’ve used it for a couple of months now and love how comfortable it is on the wrist, how visible the screens are, and how helpful the solar – lunar data is for fishing.

The GBX100 retails for $160 but you can find it on sale online (I got it for 20% during an rei.com sale), and at 15% off at POP during December.
