Read this blog ! Practice your English! Come on ( venga ya)!. No deadlines (fechas tope). No exams. It's just a fun way to learn the language.
I have read all the article and I think I can answer to some of your questions. First of all, I agree with you, we live in a moment where the watches are a little bit "old", now everybody use their mobile phones to know what time is. Secondly, the students in the exams can't use the mobiles but, at least in UEM, we can see the time in the left corner of the blackboard. Finally, about the "clock tower", I'm not 100% sure about if it is what I think but there is a clock in the sports centre in D building.
