It's okay. I'm a fan of the numeral + marker dial (Nomos club as one example), the mix of surfaces on the dial is nice, and I'm a sucker for a hand winder. But, I'm not sure how I feel about the hands, and I think a polished top bezel would work better with this design. Is it dressy, is it tooly, who can say? Also don't think the Zelos logo looks great with this particular watch (works well on their divers IMO). Perhaps some other colors would resonate with me more.
However, not totally sure how this would be a competitor to a Halios...does the Zelos have diver specs? Even if it does, I don't totally buy that it'd be a serious option for someone in the market for a Halios. Much like Zelos, Halios has a very distinct design language that permeates all of their watches to one degree or another. I don't necessarily see these two brands competing against one another for the same slot in a watch collection, specifically from a design perspective.
