Fifth Question

Exploration Stage: Post Office
From: Mr. Black
Description: Your evidence looks convincing, but it's not enough. We need to make sure the title of Mystery Solver isn't just empty words. If you are chosen by the City, it will reveal information that nobody knows to only you! Where is the Collector now? Where did he go?
Completed: There are two dials on this watch, each showing a different time. The watch surely belongs to the Collector, but what does it mean?
