Whatever you do, own it with the Instinct 2/2S series of rugged GPS smartwatches. They're tough enough to keep up with you and unique enough to fit your style. Instinct 2S/2S Solar models are slightly smaller, coming in at 40mm as opposed to 45mm on the Instinct 2/2 Solar, which will fit smaller wrists better. Non S models also feature a slightly longer battery life.
