"Naquele relógio"

[aniger]

Why can't it be something "on" the watch, such as a leather strap?

[Ker]

Thanks we will fix it!

[robdas]

Why is "in THIS watch" wrong?

[Ker]

There is nothing wrong with the sentence, but it becomes hard because there is no context, so we are changing it. Thank you!

[Quentinho]

Cheers!

The dictionary also lists "at that" as an acceptable answer yet it's marked wrong.

[Quentinho]

What is it supposed to mean?
