Diesel’s new Full Guard 2.5 is the biggest Wear OS watch yet

Diesel is a watch sub-brand of Fossil that is perhaps best known for making large watches. It was no surprise, then, when Diesel launched its first Wear OS (then Android Wear) watch last year called On Full Guard. It was one of the largest smartwatches around, measuring in with a 48mm case.

While other watch companies may have taken the year-long gap between products to try and shrink that down a bit, Diesel has made the less popular but somehow equally unsurprising decision to make a follow-up, the Diesel Full Guard 2.5, which is even bigger (via Gizmodo).

With its 56mm case and full 2.5-inch display, the Diesel Full Guard 2.5 is the biggest smartwatch on the market. It runs Google’s Wear OS, with NFC for Google Pay, and it has a heart rate sensor and integrated GPS for fitness tracking. Diesel claims that you’ll be able to get up to two days of battery life from the Full Guard 2.5. That would normally be a lot for a smartwatch, if not for the fact that the Full Guard 2.5 is so absurdly large that it’ll have plenty of room for a nice, hefty battery.

Diesel will sell the Full Guard 2.5 in three versions: a gray case with a brown strap, a black case with a gray strap, and a black case with a black strap. It’ll go on sale sometime in October, although no price has been announced yet.

Fossil’s latest smartwatches have Google Pay, heart-rate tracking, and GPS

Fossil’s smartwatches have always eschewed features for simplicity and affordability. They put Google’s Wear OS software on your wrist in a clean design that looks like a traditional watch, and that’s it. Many of them haven’t offered heart-rate tracking, and zero have allowed owners to make mobile payments with their wrist. But that’s changing now. Today, Fossil announced the fourth-generation of its Fossil Q lineup, and the latest models add all of those features (and also standalone GPS).

These new watches — the Q Venture HR and Q Explorist HR — range in price between $255 and $275 depending on your band and color preference. They’re available immediately from Fossil’s website. The Q Venture HR has a 40mm stainless steel casing, and the Explorist has a larger 45mm case.


Unfortunately, Fossil is sticking with the aging Qualcomm Snapdragon Wear 2100 chip that has been used in smartwatches for two years now. A new, more powerful SoC is coming this year. But don’t expect these devices to make Wear OS run with a revitalized sense of speed or fluidity.

Still, if you want a smartwatch that can handle fitness tracking and make Google Pay transactions with a tap (and do both in a package that’s not bulky or overly “sporty”), then the new Fossils might be worth trying on, even if it seems like Google is barely putting any significant work into Wear OS these days.
