Lower armband may haps?
Get some of that fancy flex tech for screens toss it on an lower arm band water proof it as much as you can turn that into your smart phone. At least that have a use all the power of a smart phone or tablet with more show off of then a digital watch. Put gold on it and it will be big in Dubai and coffee bars. Personally I want mine in gun metal grey with a blow torch and stun darts.
