The Engineer Hydrocarbon collection consists of exceptionally resilient timepieces. The Engineer Hydrocarbon Midsize timepiece is equipped with Swiss-made ETA 2892-2 automatic calibre. For convenience, it comes with a 42-hour power reserve. The timepiece is protected from adverse conditions – extremely low temperatures, water penetration and shock. Dial elements are illuminated during the night through the usage of 32 micro gas tubes. The uni-directional rotating bezel can be used to measure elapsed time. Additional functionalities include a date window between 4 and 5 o'clock, screwed-in crown and scratch-resistant sapphire crystal glass with anti-reflective coating.
