Back in 2019, German watchmaker Sinn and watch publication Revolution collaborated on the 155 Bundeswehr “Dark Star,” a black version of the former’s famed 155 chronograph, but featuring the latter’s star symbol at the bottom of the dial. Limited to just 150 pieces, this watch had a domed plexiglass crystal and a weathered appearance with a bezel effect that made it look old and a custard-colored Super-LumiNova meant to look like aged tritium. Five years later, the two brands reunite for a follow-up, this time doubling the edition size and focusing more on modern tech to get the job done.
Not merely random, the aged look on the 2019 watch was a tribute to the model’s long history, dating back before even Sinn got its hands on them. The original 1550 SG chronographs were commissioned pieces made by Heuer for the West German Federal Defence Force. They were given Bund straps, which put an extra piece of leather behind the caseback to protect fighter pilots from rising temperatures of the metal on their skin. In the 1980s, Sinn acquired decommissioned chronographs, refurbished them, and sold them to civilians as the 155 Bw. While reissued a handful of times in the 21st century, the watches have always strived for the same specs and overall aesthetic as the originals.
Rather than going for a worn look, the stainless steel case on the new 155 model features a TEGIMENT-treated case, which is Sinn’s proprietary tech that hardens the steel to prevent wear and scratches over time. Dubbed the 155 S Bright Star TEGIMENT for its lumed star on the dial, the bi-compax chronograph is the first 155 watch to be all black and the first to feature a sapphire crystal (rather than plexiglass). Like previous iterations, this Bright Star version is housed in a 43mm case with a bidirectional 60-minute bezel. Powered by a Sellita SW510 chronograph movement, the timepiece returns with a Bund-style leather strap like the vintage pieces.
Limited to just 300 pieces, the Sinn x Revolution 155 S Bright Star TEGIMENT is available for pre-order from Revolution’s site for $3,600.
