How do I gain access to the clock tower

[Dlamica]

As title says. I am on day 61 and I can't find it . I am assuming the clocktower to is room 19 in the directory bc that one is still empty.

Hmm, it's permanently unlock from the Drafting Studio no ?

Room 19: Isn't the clocktower It's The trophy room. I didn't run into it until I had received my first trophy.
