Tag Heuer has announced a new Connected watch, bringing some innovation to smartwatches with modularity.

It looks very much like the previous Connected watch, with both offering a sporty style and firmly placed in the luxury segment of the smartwatch market. 

So which Tag should you go for? Here's how the differences break down. 

  • Both offer sporty design
  • Modular 45 offers much greater customisation
  • Better waterproofing on Modular 45

The Tag Heuer Connected Modular 45 sticks to the same design as the Connected, offering sporty looks like Tag's "normal" Carrera watches. Both watch bodies are titanium (although there's rose gold and other material options), but the original Connected is grade 2, the new Modular 45 is grade 5, a titanium alloy.

The Modular 45 is a smaller diameter at 45mm compared to 46mm of the older model. The older Connected is 12.8mm thick whereas the new Modular 45 is 13.75mm thick. The new Modular model is 62.5g compared to 52g of the 2016 model. 

The case back on the new Modular 45 is also titanium, whereas the original Connected is plastic. The original watch is IP67 rated, whereas the new Modular 45 is rated to 5ATM, so it's better protected.

However, the biggest design change is that the lugs are a separate piece from the watch module - so the lugs can be changed - and the watch module can be swapped from the Android Wear unit to a mechanical unit on the Modular 45. You'll be able to buy a Calibre 05 automatic or tourbillon chronograph module separately, providing a lot more options.

The strap designs are similar, with both offering rubber in many colours, leather, ceramic and metal band options.

  • AMOLED display with higher resolution on the 45
  • Old Connected has a larger display 

Ignoring the mechanical options on the Modular 45, the new watch comes with an AMOLED display that's 1.39-inches diameter with a 400 x 400 pixel resolution, for 287 ppi. The original Connected has a 1.5-inch LCD display with 360 x 360 pixel resolution for 240ppi. 

The new model is smaller, but it's a better type of display technology with a higher resolution, so it's going to look better.

Both are topped with a sapphire glass cover. 

  • Same processor
  • Less RAM in the new watch
  • Same battery 

Both watches are Intel powered, the Connected offering an Atom Z34XX processor with 1GB RAM and 4GB storage. The new Modular 45 is also powered by an Atom Z34XX processor, but is detailed as having 512GB RAM and 4GB storage. There's unlikely to be much difference in performance. 

Both Tag Heuer models also have 410mAh battery that use contact changing. Both watches also claim to be able to give you 24 hours of use, although the new model is pushing a higher resolution display and has more sensors to support. 

  • Modular 45 gets NFC
  • Modular 45 gets GPS

The new Tag Heuer Connected Modular 45 gets a range of new upgrades that open the door for more options. Both watches offer the regular Bluetooth and Wi-Fi for connectivity, and both also include motion sensors and gyroscope. 

The Modular 45, however, has GPS, meaning its better placed to serve you as a sporty device. You'll be able to track your location in various apps, so you'll know how far you've walked, run or biked without the need for your phone.

NFC also means you can use the Modular 45 with Android Pay. This adds convenience, meaning you can just tap your watch on compatible payment terminals, so there's no need to get your card or phone out of your pocket.

  • Tag Heuer Connected is £1100
  • Tag Heuer Connected Modular 45 from £1400

The Tag Heuer Connected is £1100, with the Modular 45 £300 more at £1400. As detailed, you get a range of enhanced technologies for your money like those additional sensors and a better display. The expense is more likely to be explained away by the modular nature, in addition to the titanium backplate. This is only at the core level, however. 

The advantage that the Modular 45 offers is the wide range of customisation you're offered. Although the Connected offers 11 base models - apart from opting for the £7500 rose gold body - the only real difference is the strap.

The Modular 45, however, has 56 base models in the collection. Not only can you choose the straps, you can choose the lugs - diamond set, rose gold, black ceramic - you can change the buckle, buy a mechanical watch body to replace the digital body, as well as pick a body that with a different colour bezel.

There's the potential to spend a lot more money with the Modular 45 as you choose the perfect watch for you, but at the same time, there's so much choice, you can make your watch a masterpiece.
