Teasers for a new Motorola Moto 360 smartwatch have been coming thick and fast this month and today we can bring you another set of leaked pictures of the second generation wearable, courtesy of @Upleaks. Furthermore, the prolific leakster suggests that a Sport version of the smartwatch is in the works too.

The pictures of the Moto 360 (2nd gen) match up with the previous leaks, showing off a metal build and a variety of leather and metal straps. There also appears to be a third rose gold color option, which wasn’t mentioned alongside the silver and black options that leaked yesterday. The Moto 360 Sport appears to swap out these materials for a plastic case which doesn’t look to offer changeable straps. We don’t have any specifications at this point, but this seems to suggest a waterproof case of some sort, which is pretty much a requirement for a sports wearable.

The rumor also gives us two potential launch dates for the products. The new Moto 360 could arrive sometime in September, while the Sport variant may have a later release around November time. Given that sports wearables still remain the most popular market segment, a dedicated fitness product could help Lenovo reach a wider audience with its new watch.

What do you think about the latest rumors, and which features are on your wish-list for a next gen smartwatch from Motorola?
