Speedmaster '57 Omega Co-Axial Chronograph 41.5 mm by Omega
The "Speedmaster '57 Omega Co-Axial Chronograph 41.5 mm" (reference 3188.8.131.52.01.002) is from Omega's "Speedmaster" collection. It features a black dial and is encased in a stainless steel case. This watch is designed for men. 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 which has a power reserve of 60 hours and displays for hours, minutes and seconds (small second). The movement offers the sporty 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 caliber has a co-axial escapement. Other features of the movement: free-sprung balance and silicon balance spring.
The case is carried on a leather strap with a pin buckle. Omega asks its official retailers to sell the watch at about 7'950 CHF. Please use the "Contact Shop" button to ask an official store of your choice for their offer."
