If you like the look and feel of a classic analog watch but crave the functionality of a smartwatch, the newly released Tag Heuer Connected Modular 45 Watch offers both. How? You can swap out the 45mm smartwatch module — powered by Android Wear 2.0 — with a purely Swiss-made mechanical option that transforms the watch into a traditional luxury timepiece. But it’s not just the watch modules that are interchangeable, as just about every part of the watch, including the straps, buckles and lugs, can be replaced. There are 11 different core designs, with the watch module available in either silver or black, alongside a slew of different material and color options, including patent leather, 18K rose gold and titanium with diamonds.
