OMEGA Speedmaster 38

The Omega Speedmaster 38, reference 324.30.38.50.02.001, is a chronograph with a 38 mm steel case. The case measures 14.7 mm thick with a lug-to-lug span of 44.9 mm. A silver dial sits under a sapphire crystal treated with anti-reflective coating on both sides. The self-winding movement is the calibre 3330, built with a column-wheel mechanism and Co-Axial escapement, and runs with a free sprung-balance and silicon balance spring for 52 hours of power reserve. Beyond the chronograph function, the watch offers a date display, small seconds and a tachymeter scale, and it carries chronometer certification. A steel bracelet with a butterfly clasp completes the piece. Omega rates the case to 100 metres.
