Crafted from steel with a round, 40mm case and matching steel case back, this Speedmaster Moonwatch Professional carries the hallmarks that have defined the line for decades. The black dial sits beneath an anti-reflective, scratch-resistant sapphire crystal, while a fixed bezel frames the overall silhouette with understated precision. Water resistance is rated to 100m/330ft.
Powering the watch is an automatic movement certified as a chronometer by COSC, delivering chronograph functionality alongside the accuracy standards the certification demands. The steel bracelet features a brushed and polished finish and is secured by a push button folding clasp.
Reference 311.30.42.30.01.003 is presented in new/unworn condition, making it a compelling opportunity to acquire one of watchmaking's most storied chronographs without compromise.
