Seiko series 5
A UH-60 Black Hawk pilot in the US Army. The Seiko 5 was a gift to self after flight school, and the first hard-core daily driver analog watch in years. It has survived real world use, with "just enough lume to be seen in complete blackout." Two years of wear and tear and about 200 hours of helicopter vibrations later, it is "just starting to show signs of time creep." What was the first watch you bought yourself after finishing a school? If you have a wrist shot from somewhere that matters, submit at the link in bio. Tempus Est Potentia.

Seiko 5
The first Seiko 5 arrived in 1963 as the Sportsmatic 5, which Seiko describes as Japan's first automatic day-date watch. The number stood for five promises Seiko made about every watch in the line: an automatic movement, a day and date display at three o'clock, water resistance, a recessed crown at four o'clock, and a case and bracelet built for durability.
UH-60 Black Hawk
The Black Hawk came out of the Army's Utility Tactical Transport Aircraft System program, started in the late 1960s to find a successor to the Bell UH-1. Sikorsky's YUH-60A won a fly-off against the Boeing Vertol YUH-61 in 1976, and the UH-60A entered Army service in 1979. The aircraft is named for Black Hawk, the Sauk leader.
