Glycine timepieces were created specifically for pilots. Glycine is one of the first watch manufacturers to measure time across the world. Combat watches were developed for adventurers and extreme sports enthusiasts. Glycine is well known for its Airman brand of GMT watches, which include 24-hour analog dials and rotating bezels and are popular among military and commercial pilots. The Airman is a stunning vintage aviation-style watch that is one of Glycine's most recognizable collections. The Airman is ideal for any international traveler, thanks to its leather-stitched bands and ability to measure several time zones. While Glycine's Combat watch line is noted for its strength and durability, this range of clocks stands out from the others thanks to high-grade steel, sturdy construction, and a classic 1960s-inspired design.
