I don't have a good enough overview of the current watch market, nor of the history of watch design; I'll go though my collection of pictures in the evening to suggest a few examples that fit the bill. I suppose one design like that was that dot-matrix radio-controlled Seiko that everybody loves, but then again, that thing's been around for five years at the least. But it was definitely very modern at the time of its release, so to me, it's worth mentioning.
Oh yeah, one more thing: it would be easy to say that the only modern design is a solar-powered, capacitor-backed digital watch (accurate, easy to read, months of autonomy, very little to break down, essentially maintenance free). I think to get anything meaningful out of the discussion, the realities of the "watch universe" should be considered, but even a mechanical chronograph may be a simple reissue (very non-modern) or a product at which the designers worked hard in order for it to make sense in the present moment, if you know what I meean.
