Swatch is heeding the warnings. The company said it is introducing fitness functions, a key feature of smartwatches, to its Touch line of digital watches to be launched in 2015. Industry analysts see brands like Swatch as being more vulnerable to the wave of smartwatches than more luxury-focused competitors. They also predict that once the iWatch hits the market, Smartwatches could take away as much as 10% of the sales of Swatchs entry-level watches and 5% of its mid-range brands, which include Tissot and Mido. Apple will be the real test. The upcoming launch of Apples smartwatch could be the biggest challenge Swatch has faced since digital watches upended the market. Earlier this year, Swatch opposed Apples attempts to trademark the iWatch name in several countries, claiming it was too close to the companys own iSwatch. However, the success of smartwatches is far from assured. Internet-linked watches made by Sony and Samsung have had disappointing sales thus far. Yet, technology is what most of the younger generation wants. Another brand that makes wearable smartwatches is Pebble. Their smartwatch was a crowdfunded phenomenon and is reported to have sold over 100,000 units. It has a 1.26-inch LCD screen and is compatible with both Android and iOS. Car manufacturer Nissan has also recently announced the launch of its own smartwatch, which highlights how advances in technology blur the boundaries between different industries. Nissans smartwatch Nismo will enable users to monitor their vehicles efficiency by measuring average speeds and fuel consumption. The only concerns about smartwatches are to do with battery life, comfort and screen size. A significant hurdle facing the smartwatch is its design. A watch is ultimately a fashion accessory, which means it is going to be huge challenge for a first-generation smartwatch to have mass market appeal. If the choice is going to a fancy party sporting a Piaget or a Rolex rather than a Pebble or Galaxy Gear, its a no contest.
