The Engineer Master II Telemeter is the world's first night-readable mechanical telemeter timepiece. It is equipped with Swiss-made Valjoux 7750 automatic calibre that has 27 bearing jewels. A 42-hour power reserve is available for the convenience of the wearer. Hands, numerals and indices are illuminated through the use of 27 self-powered micro gas tubes that glow 100 times brighter than luminous paint. The watch is protected from shock, magnetic influences and water penetration. Accumulated chronograph measurements reach up to 30 minutes. Other useful functionalities include a telemetric scale, subsidiary seconds, day and date display at 3 o'clock, screwed-in crown and scratch-resistant sapphire crystal glass with anti-reflective coating.
