Ruth Belville's Pocket Watch

Origin
Ruth Belville, also known as the Greenwich Time Lady, and her parents were well known in her local area as sellers of time. Every day they would trek to the Greenwich Observatory and wind their pocket watches to the correct time as shown on the Greenwich Clock, then travel back into town and allow people to see their watch for a small fee. Through these means the people of Greenwich were always able to tell the time and set their own clocks.

Effects
When wound, all timepieces in the area will adjust to show the time on the pocket watch. This includes digital clocks, watches, computer displays, egg timers and even, through unknown means, hourglasses. Once changed their time will continue to run as if nothing had happened, despite showing the incorrect time.

It also has an interesting effect on individuals tied to the flow of time, causing them immense disorientation and even blackouts due to their internal clock going out of synch. Because of this, the pocket watch is kept as a means of incapacitating Warehouse consultant Juan Miguel if need be.
