I'm not fond of plastic, rubber, or silicone watch straps. I prefer leather, nylon, or steel bracelets.For a Suunto Vector, leather doesn't make much sense an a proportionally sized steel bracelet would weigh more than the watch and have me walking lop-sided. But the attachment points on the Suunto aren't amenable to a strap wide enough for the watch.So Suunto offers this accessory. Installing the two plastic loops for the strap requires two screwdrivers and some coordination, but I was able to do it with just the screwdrivers. The attachments were fairly obvious, and went on easily enough.It is well made for the kind of environment where the Suunto watches wouldn't look completely geeky, and the plastic attachment points could be used for other nylon straps.It makes the Vector a lot more comfortable for me.E.M.
