The first thing you should know about Traska as a brand is that all of its models have reasonable dimensions. The Summiteer comes in two sizes, one with a diameter of 36.5mm and one with a diameter of 38.5mm. The smaller version has a lug-to-lug of 44mm and a total thickness of 10.55mm. The larger version has a lug-to-lug of 46mm and the same thickness of 10.55mm. Both models feature a 20mm lug width and a fully-articulated bracelet that tapers from 20mm at the lugs to 16mm at the clasp.
