Wristwatch/Piano wire garrotte
Used with lethal effect by Red Grant, this device is a wristwatch, which conceals a retractable piano wire that can be used to strangle victims. Grant kills Bond's double at the SPECTRE training school using the wire and attempts to murder the real 007 in a brutal fight aboard the Orient Express. Alas, Bond turns the tables and kills Grant with his own device.
