The AVI-8 Flyboy Engineer Automatic AV-4075-22 has a utilitarian case of Stainless steel. With a 42mm diameter the case it will fit perfectly on most wrists. The domed, scratch-resistant sapphire crystal adds to the ruggedness of the watch, and makes it suitable for everyday wear. The light, sword-shaped hands contrast nicely with the dark dial (and colormatched date window) for excellent legibility. This watch comes on a comfortable stainless steel bracelet.
