This Omega Speedmaster Professional automatic chronograph measures 39mm across. It was manufactured by Omega in the late-1990s and features a triple-date and triple-chapter chronograph, with day/night (24-hour) indicator. The domed, coated (glare-resistant) sapphire crystal is in fine shape, as is the case and Omega bracelet. The Omega automatic winding movement is flawlessly functioning and accurate. The exotic dial is very colourful having a grey background with black chapters and blue 24-hour chapter.
