Omega 378.0801 Speedmaster 125 SS Black Dial

The Omega Speedmaster 125, reference 378.0801, stands as a truly monumental release from 1975, representing an ambitious milestone in chronograph history. Introduced to commemorate Omega’s 125th anniversary, this pioneering chronograph was the first automatic chronograph wristwatch to achieve Chronometer certification, powered by the robust caliber 1041—a highly modified Lemania base. Its imposing 42mm by 51mm stainless steel case, an enduring testament to 1970s design, balances bold geometry with remarkable wrist presence. The integrated stainless steel bracelet underscores its period-correct styling, while the deep black dial delivers excellent legibility with applied hour markers and crisp chronograph registers. Complication-wise, collectors value its combined chronograph and date functions, all integrated seamlessly into the reliable automatic movement. While not intended for aquatic exploits—its case is not water resistant—the Speedmaster 125 earns distinction as a technical and historical landmark. Its rarity is amplified by a limited production run, making it highly sought after by discerning collectors appreciative of Omega’s legacy and boundary-pushing spirit. In the pantheon of Speedmasters, few iterations carry as much horological gravitas as the 125—a chronometer-certified chronograph that set expectations for generations to follow. Excellent condition.
