If you like watches, you probably have strong feelings about smartwatches. On one hand, you’re probably in favor of watches that do as much as possible, even if it’s not something you’d use (what lunar phase is it?), but on the other hand, an electronic device is so far divorced from most of the elements of horology that you love. As a result, you may have briefly considered one of the sexier examples, like the Asus ZenWatch, but then decided to just stick with your existing watch.

Montblanc clearly feels similarly, and has announced the E-Strap, which attaches to your existing watch and has a small device that sits under your wrist that performs some basic smartwatch functions. It works as the obligatory fitness tracker, shows email and SMS previews, caller ID, alerts the wearer based on calendar apps, and give social media updates. It’s compatible with Android and iOS, and will cost around €250 (~$300 USD) when it goes on sale.
