Maybe one of the boldest smartwatches cash can purchase, the Diesel On Full Guard 2.5 isn't for everybody – except it isn't intended for everybody either.

Not at all like the Apple Watch 4 or Samsung Galaxy Watch, this is purposefully worked for the individuals who like Diesel's style instead of a more extensive scope of individuals. It's enormous, it's massive and that is deliberate; you'll either adore or detest the structure.

In the UK we've spotted it at around the £290 mark, while in the US it's still around the RRP. This isn't the least expensive smartwatch cash can purchase, yet thinking of it as' a high-spec gadget with an excellent structure it is anything but an awful cost either.

Design and display

It's one of a kind, however that is not an awful thing. A ton of smartwatches – particularly in the Wear OS space – tend to resemble the other the same, so we're glad to see Diesel have a go at something somewhat extraordinary to the remainder of the market.

It's an enormous and substantial watch. Much like the first Diesel On Full Guard, this will suit those with bigger wrists who like a bulkier gadget.

It has measurements of 47 x 56 x 13mm, and that may sound a ton on paper however we didn't see the gadget as excessively thick on the wrist. It is huge however.

It's a round watch with a 1.39-inch show in the center and there's a serious thick bezel around the outside of that when you contrast it with gadgets like the Apple Watch 4. The impact around the head of the watch looks punctured, and it's an impact that we like the vibe of.

We utilized the rendition that is a blend of dark and red, but on the other hand there's a lighter form with a silver body and lash, just as a simply dark variant with a dim tie.

That tie we had is made of silicone and keeping in mind that we thought that it was got filthy rapidly it has a pleasant plan that many will discover agreeable. It additionally does a decent of holding the watch set up when you're wearing it, regardless of the heaviness of the watch.

In any case, in case you're not into silicone you can likewise get the watch with different lashes, including calfskin and metal. A portion of these do cost somewhat more however.

On the correct hand side of the Full Guard 2.5 you'll discover three fastens that will permit you to wake the gadget and explore around. For one thing, a catch camouflaged as a crown sits at the 3 o'clock mark. We especially like this as turning it permits you to burn through menus on the watch's showcase.

Above and underneath it there are littler catches that can be customized to your requirements. As a matter of course the top catch dispatches some Diesel highlights and the base catch begins Google Fit, yet you can change what these initiate in the settings easily.

We saw the presentation of the watch as large enough that you can associate with it effectively, the goal is high at 400 x 400 and it's brilliant enough to easily use every day.

The Diesel On Full Guard 2.5 functions admirably, however it's not the quickest watch we've at any point utilized.

The Qualcomm Snapdragon Wear 2100 chipset utilized inside has been around for two or three years at this point, and it's beginning to feel somewhat drained as far as everyday execution.

We wish the organization had utilized the refreshed Snapdragon Wear 3100 chipset that is inside the Montblanc Summit 2 and Fossil Sport, however that doesn't mean this watch is unusable.

The Full Guard 2.5 can deal with ordinary errands easily, and keeping in mind that it won't overwhelm you with its speed it's far-fetched you'll discover this continually baffling to explore around.

Different highlights on the watch incorporate NFC, which permits you to make contactless installments utilizing the Google Pay application. We discovered this to work rapidly and effectively - it's a major advantage in the event that you ever end up without your cards on a run or an excursion to the shop.

The watch likewise associated with the Wi-Fi effectively, so you don't generally must have your telephone close by to utilize it. It's significant that there isn't a LTE variation of this watch however, so you wont have the option to get warnings and such without your telephone.


The Diesel On Full Guard 2.5 comes running Wear OS programming, which implies it's perfect with both your iPhone and Android gadget.

The Full Guard 2.5 gives you a plenty of watch countenances to look over just as every one of those applications, and we like the manner in which you can dodge and plunge around the product easily.

On the off chance that you've utilized an Apple Watch in the past you may think that its somewhat hard to become acclimated to Wear OS, yet it shouldn't require you much exertion as it's a comparable kind of interface.

The center distinction here to different smartwatches is the reality you can show Diesel watch faces. There's an application to discover these on the watch called Diesel T-On-I, and these change the fundamental screen of the gadget to give it a novel and clear look.

This is a straightforward method to see the entirety of your center details, for example, your progression tally, your plan for the afternoon and what climate to anticipate. It is anything but a center selling purpose of the watch, yet you may think that its a stylishly satisfying decision in case you're a major enthusiast of the Diesel brand.

Google Assistant worked rapidly on the watch – or as speedy as it does on other Wear OS gadgets – and we preferred how you can rapidly pose inquiries and find a solution over Bluetooth right away.

At that point there's the cell phone application that interfaces your watch to your telephone. Similarity savvy, you'll have the option to utilize the Diesel On Full Guard 2.5 in association with your Android gadget as long as it runs Android 4.4 or higher programming.

It likewise works with an assortment of iPhones, yet on the off chance that you have a more seasoned gadget you might need to check the similarity on the official Diesel site.

Rather these are decent augmentations that you may discover valuable to follow your day by day wellness or the odd run. Anyway it has GPS implicit, so you won't need to take your telephone with you to follow your area when out practicing with this tied around your wrist.

In addition, there's a pulse screen on the back of the watch, which we saw as precise and to work rapidly.

The Diesel On Full Guard 2.5 is likewise waterproof, so you'll have the option to bring this into the pool and track your exercises there. We haven't yet tried the swim highlights of the watch, however these have functioned admirably on past Fossil smartwatches we've utilized.

In general, don't accepting the Diesel On Full Guard 2.5 for its wellness ability, yet rather think about this as a decent touch that gives you the additional advantage of having the option to check your pulse or your progression tally.

Battery life

Battery is a region where the Diesel On Full Guard 2.5 battles, and it's one reason we wish we had seen the organization grasp the more up to date Snapdragon Wear 3100 stage.

We once in a while got past an entire day without the Diesel watch waiting be revived once more.

With insignificant use you might have the option to get two brief long stretches of utilization out of the smartwatch before expecting to charge it, however every time we attempted to go a night without putting it on the charging cushion it wouldn't arrive at the finish of the subsequent day.

With more escalated utilization – that is utilizing GPS, warnings and different highlights – you'll discover the watch will last precisely a day.

This watch in fact charges remotely, yet you won't have the option to utilize any Qi charger. Rather it utilizes an exclusive charger, so you will need to make sure to take that with you when you disappear.

Energizing it doesn't take long however and we discovered it could charge from void to full in around an hour and a half.
