| Although the Engineer was one of Crews' first, it is still one of the most popular of its styles. Constructed from a nickel-silver alloy it is available in two fashionable styles: Aviator (54mm or 58mm lenses) and Conventional (58mm lenses). It boasts spatula temples constructed of a brass alloy for easy adjustment and had a nose pad that is adjustable and constructed from soft, pliable PVC. Sideshields are permanently attached. The Lady Engineer features the same construction as the Engineer, but in a 55mm round lens to conform to smaller faces. Replacement lenses are available.
