The TechnoSport TS-100-AV series models are well built, quality timepieces built in the Aviator style. The octagonal 44mm case of this men's watch is solidly constructed from black ionic-plated stainless steel and houses a very reliable Swiss Quartz Multifunction movement. The color theme for this timepiece is pure black. The stationary bezel offers 8 hex-head screws done in silver which create visual interest against the black bezel. The dial offers a finely textured pattern done in black. Stick-style silver hour markers are present at every hour position. The outer area of the dial provides a rotating chapter ring with 24 world cities listed and allows for the determination of the current time throughout the globe. This ring is controlled by the knob located on the left side of the case. The tips of the hour and minute hands are coated with a luminous material which will glow green in the dark after exposure to a strong light source (i.e. sunlight). The date is located in the subdial at 3:00 and is controlled by the upper right hand function pusher. The subdial at 9:00 displays the day of the week and is set by the lower right hand function pusher. The 6:00 subdial is the 24 hour am/pm indicator. At 10 atmospheres of water resistance, this TS-100-AV is perfect for surface swimming activities. The silky-soft black silicone strap is 9 inches in length. Stylish good looks and fantastic value: This TechnoSport has it all and delivers it at an accessible price! (Please note that most TechnoSport watches will arrive with a protective film covering the crown and any function pushers. These may be seen in our photography as blue or purple colors but they are designed to be removed once your watch arrives).
