The AVI-8 Flyboy Eagle Squadron Automatic Bronze 85th Limited Edition commemorates the 85th anniversary of the Eagle Squadrons—American volunteer pilots who flew for the RAF before the US joined WWII. The collection includes three distinct variants, each representing a historic squadron and location: Gravesend (AV-4145-01), Southend (AV-4145-02), and Coltishall (AV-4145-03). These watches feature a genuine bronze case designed to develop a unique patina over time and a "hidden courage" dial that reveals a secret inscription under UV light: "First from the eyries / For liberty / Let us to the battle".

Each variant is distinguished by its color scheme: Gravesend features a black sunburst dial with a blue leather strap, Southend sports a blue sunburst dial with a brown leather strap, and Coltishall highlights a green sunburst dial with a black leather strap. All models utilize a compact 39mm case with a notable 15mm thickness, emphasizing a rugged yet balanced pilot's watch silhouette. The commemorative package includes an additional strap—either a secondary leather or NATO style—and anniversary-themed packaging to honor the squadron's legacy.

The collection is powered by the reliable Miyota 8215 automatic movement, a Japanese caliber featuring a 42-hour power reserve and a 21,600 vph frequency. The movement is visible through a sapphire exhibition case back, which also bears the squadron's eagle emblem and a unique limited-edition number. With only 175 pieces produced per variant, the Eagle Squadron 85th edition is a rare, technically robust tribute to aviation history.
