Casio’s rugged G-Shock GD-100-1B watch is now down to $52.64 on Amazon for a limited time, reaching its all-time low price. With a rugged, shock-resistant build, 200 m (20 bar) water resistance, world time across 31 time zones, and 7 years of battery life, it’s a great deal for analog watch enthusiasts.

The Casio Amazon storefront is currently offering a massive 47% discount on its G-Shock GD-100-1B watch. This means you can now snag this analog watch for just $52.64 rather than its original list price of $99. It’s certainly among the best deals in recent months, and Camel’s price history cements that. According to the Amazon price tracking website Camelcamelcamel, this is the all-time low price recorded for this model. Buyers, keep in mind that this is a limited-time deal, and currently it’s unclear how long it will last. 

The G-Shock GD-100-1B has a resin-made, shock-resistant sporty design, which is sturdy enough to handle daily wear and tear. If you’re more into water sports, then you’ll be pleased to know that the watch features 200 m (20 bar) water resistance, making it the perfect companion during light water sports activities. 

Despite being an affordable G-Shock, the watch is said to offer 7 years of battery life via its CR2025 power cell. This means you won’t have to worry about frequently replacing the battery. Additionally, you get dual-time support for tracking two time zones at once and a world time feature across 31 time zones. The key features of the G-Shock GD-100-1B include a 1/100 second stopwatch, a full auto calendar up to the year 2099, 5 alarms, and an LED light with afterglow. 

If we take a look at Amazon reviews, the watch scored a solid 4.7 out of 5 stars across 1,868 ratings, with users speaking in favor of its durability, functionality, and affordability. Overall, at around half of the original price, the Casio G-Shock GD-100-1B is a solid deal if you’re looking for an affordable G-Shock with functionality and a great battery life.
