Idris Elba wears an Omega Speedmaster

Derek Charles has the executive position, the house, the wife played by Beyonce, and the careful composure of a man who senses how fragile all of it is. Steve Shill's Obsessed (2009) puts Idris Elba in a corporate thriller where a temp's fixation methodically dismantles his life. On his wrist is an Omega Speedmaster, the steel chronograph with three registers and a tachymeter bezel, here with a bright silver dial. It is the watch of a man who has arrived, expensive without being loud, the sort of quiet success a stalker might fix on as something to take apart.
