The OMEGA Speedmaster ’57 Chronograph 41.5mm (Ref. 331.22.42.51.01.001) honours the original 1957 Speedmaster through its distinctive bi-compax dial layout with seconds subdial at 9 o’clock and combined 12-hour and 60-minute recorder at 3 o’clock, differentiating it from the tri-compax Moonwatch configuration. The 18K red gold tachymeter bezel mounted on the stainless steel casebody creates warm two-tone contrast whilst the black dial with central chronograph seconds hand and date at 6 o’clock provides comprehensive chronograph functionality.

At 41.5mm with 16.17mm thickness through steel and red gold construction, this provides substantial chronograph presence whilst the two-tone combination creates a more refined proposition than a full steel Speedmaster. The scratch-resistant sapphire crystal with anti-reflective treatment on both sides ensures optimal legibility whilst the brown non-grained calf leather strap with foldover clasp provides sophisticated daily wear appropriate to the precious metal bezel.

The Co-Axial Calibre 9300, the first chronograph in OMEGA’s family of in-house Co-Axial mechanical movements, delivers 60-hour power reserve through column wheel construction with silicon balance spring on free sprung-balance and two barrels mounted in series. The time zone function, chronometer certification, and rhodium-plated finish with Geneva waves in arabesque complete a movement specification that significantly advances on the original 1957 calibre it references.

The 100m water resistance and COSC chronometer certification cover practical requirements whilst the transparent caseback reveals the decorated movement. The tachymeter scale on the red gold bezel enables speed calculations that connect this directly to the Speedmaster’s original purpose as a motorsport and aviation timing instrument.
