Reference 331.12.42.51.01.002 presents the Speedmaster '57 in its most classic form: a round stainless steel case measuring 41.5mm in diameter and 16.5mm thick, fitted with a fixed bezel and closed by a transparent case back that reveals the automatic Co-Axial movement within. The black dial is protected by anti-reflective scratch-resistant sapphire crystal, keeping legibility crisp in virtually any lighting condition.
The chronograph complication remains central to the Speedmaster identity, and this reference delivers that functionality through a well-sorted automatic movement. Water resistance reaches 100 metres (330 feet), lending everyday versatility to a watch that carries a rich motorsport heritage.
A brown leather strap with a push-button folding clasp completes the ensemble, offering a warm contrast to the stainless steel case and black dial. This piece is presented in new/unworn condition.
