Grenade is modelled after the historical MKII grenade with an M6A4C fuse that uses a pin that is pulled to activate the explosive. In a similar way, the L’Epée 1839 Grenade features a pin that doubles as the key, which when pulled allows for setting the time and winding the eight-day movement. The moment you pull the pin on a grenade the mind is focused: the grenade is live, and you must concentrate on the here and now to survive.
