Smartwatch manufacturers such as Motorola, LG, and Apple have created technology to appeal to luxury and analog watch fans. Motorola released the Moto 360 with a round screen, LG did the same with the LG G Watch R, but without the small blank area under the screen that the Moto 360 had. Apple intends to release a gold version of the Apple Watch for luxury watch fans. None of these are much like the multi-thousand dollar luxury watches offered by Rolex, Zenith, Emporio Armani, and Chanel, so Montblanc developed the e-Strap technology for their luxury watches. The e-Strap costs $300 USD, but it is designed for timepieces which cost far more than that (over $3,000 USD).
Why have two watches on one band? A good reason is: Public preference for analog watches is still very strong. This may be because watches are often seen as fashion accessories. Anything that is frequently carried in-hand or worn needs to be fashionable. The e-Strap enables you to wear your Montblanc luxury watch as usual, and there is a 128 x 36 pixel OLED touch screen on the underside of your wrist. So far, this is the closest i’ve seen to having your cake and eating it too. The Montblanc e-Strap connects to your smartphone via bluetooth and displays notifications, it has a fitness tracker, among other features.
The e-Strap is “NATO-style” in terms of how it is designed and how it connects to the watch. Montblanc has made it clear that the e-Strap is debuting with the Timewalker Urban Speed but will be compatible with all 42mm or 43mm wide Timewalker watches currently or previously available. It should also fit on various other watches with similar lug space sizes (perhaps 22mm wide or so). Of course, if you simply don’t want the e-Strap, you can get the Montblanc Timewalker Urban Speed without it.
