The "Speedmaster '57 Omega Co-Axial Chronograph 41.5 mm" (3188.8.131.52.01.001) belongs to Omega's "Speedmaster" collection. It features a black dial and is housed in a stainless steel case. This watch is a men's watch. The round case is 41.5mm in diameter and water tight up to 10 bar (approximately 100 m water depth). A transparent case back makes it possible to watch the movement.
The watch is driven by an automatically winding Omega 9300 mechanical movement offering a power reserve of 60 hours and indicators for hours, minutes and seconds (small second). It has the useful chronograph (commonly known as a "stopwatch") function to measure the duration of an event. The measured duration can be read with an indicator for the seconds. A tachymeter scale allows to convert stopped seconds - or travel time in general - to speed. The movement indicates the date. As regulating organ, the movement relies on a co-axial escapement. Other features of the caliber: free-sprung balance and silicon balance spring.
