CasioG-Shock GWM5610-1 Men's Solar Black Resin Sport Watch

The Casio G-Shock GWM5610-1 is a phenomenal timepiece that delivers rugged durability, precision, and versatility. Its solar-powered battery and atomic timekeeping ensure reliability, while the shock-resistant construction makes it perfect for tough environments. The sleek, classic design offers both functionality and style, making it suitable for everyday wear or outdoor adventures. Water resistance up to 200 meters adds another layer of dependability. If you're looking for a watch that blends toughness, smart features, and timeless appeal, this G-Shock is an outstanding choice!

For the past 10 years, I've thought that mechanical watches had so much charm and passion, while quartz watches were soulless devices. I picked up this watch to be a "beater" when my automatic watches weren't suitable, but I've actually grown quite fond of the GW-M5610. What's not to love about a light, small, tough-as-nails, super accurate, solar watch?I got this watch from Amazon on April 5, 2019 (in the USA). First thing I noticed was that it did not come in the hexagonal tin box that a lot of older online reviews show, but a flimsy cardboard box with a simple display holder. At first I was annoyed, but honestly the box would have just been tucked away in storage with other watch boxes that never see any use.After unboxing, you'll find a warranty card, a handful of manuals in various languages, and the watch in a simple plastic bag (no protective stickers on the crystal or caseback, no fancy hangtags). I immediately checked out when the last sync time was (bottom right button), which happened to be on November 1. Assuming this sync happened before it was packaged up, that meant it was sitting for 5 months in the dark, but it still showed high power (as indicated at the bottom of the display, where there's a L, M, H meter). Yay for power saving mode!Next step was to set the timezone. The manual states that the default timezone after losing all power is Tokyo. I assumed this was what the watch would be shipped with, but mine was set to NYC by default. I'm curious if watches sent to the USA are set this way, or if someone played around with this watch. After selecting my local timezone (Pacific), it was only 2 seconds slow! I know quartz watches are accurate but that is phenomenal, especially considering the manual states +/- 15 seconds per month without a signal calibration.Speaking of signal calibration, I've had my watch automatically sync about every other night in Seattle. I have an old Casio Waveceptor (10 years old) that never syncs anymore. I don't know if that's because it has become defective, or the GW-M5610 can pick up a weaker signal strength. Regardless, there's no need to worry about missing a few nights in a row of syncing, as it'll still be very accurate.The caseback on mine was machined and not stamped, with crisp engraving (FYI, I removed the serial number from the image, normally found on the bottom of the caseback). As far as I know, only older models will have the stamped, rounded version. While on the wrist, it feels just as comfortable as any rounded caseback I've had.I really like that the resin strap is already pre-rounded/pre-shaped. I've had tough, flat rubber/plastic/resin straps on other watches that were incredibly uncomfortable (I'm looking at you, SKX009). On my 6.25" wrist, the watch strap keeper is right at the end, and there's maybe 1/4" excess strap sticking out. If your wrist is smaller, you'll unfortunately have more strap sticking out, which will probably be a bit annoying.Other reviews state that the A-EL feature didn't work on their watches, which is the auto-illumination when you tilt your wrist up. Mine works flawlessly. I'm curious if this was an issue with earlier models that has since been addressed.The only minor annoyance I can find with this watch is the non-standard lug width/strap. I think the stock strap fits it perfectly (both in terms of comfort and aesthetics) and have no desire to change it, but it's proprietary. That being said, I'm sure it won't be hard to find a replacement strap if needed.The GW-M5610 has a perfect blend of retro styling, useful functions, durability, comfort, and laziness (it sets itself!).

I am a watch collector. I have about 50 watches - of all different sorts: automatic, quartz, analog, digital, high-end (luxury - like omega) and low-end (timex).This watch is hands-down the best watch in my collection. Sure I wouldn’t wear it with a suit. But in literally every other occasion this watch is perfect. It’s always accurate to the second - you never have to set it. And it syncs really well with atomic time (here in the US and in the UK from my experience). Also the world time feature is perfect when traveling - simply push the top two buttons in world time mode to switch the new time zone to your current time zone.Its button configuration is perfect compared to other digital watches. And the battery will last basically indefinitely. Perhaps you might need to add a new solar powered watch battery replacement once in your lifetime if the battery stops taking any charge.The stopwatch and timer are useful for me daily. And the hourly signal on the alarm mode is great when you want to be more mindful of the time.Sure Casio makes other similarly functioned watches that are just as fun. But I think where this reigns supreme over those is its classic design, perfect functionality and button layout, and its size. And it beats a smart watch in terms of battery life, durability, and reliability. I promise you won’t dislike this watch - unless you think the design is ugly… which I understand if you do. But give it a chance and you might discover the joy and security this watch gives me.

I am a watch collector and I really appreciate analog watches, but I do love a quartz digital for casual and work wear. The 5610 is by far the greatest digital watch ever made and arguably the greatest watch of ANY kind.It's small (by G-Shock standards) and so light you barely know it's there. It has nearly every conceivable useful digital watch feature--alarm, timer, stopwatch, etc. But I was specifically interested in the solar charging and world timer functionality, which let's you store 5 zones at a time. I love that in world timer mode, it keeps home time on the same screen so you always know what time it is at home at a glance when out of town.Given all of these features, they could have made it confusing to use, not the controls are very intuitive and based on the same wonderful Casio button functionality. And, it's a G-Shock, so it's basically indestructible.I gave it 5 stars because I couldn't give it 6.
