I've come across the sentence

> 父は休みの日はずっとテレビを見ている。(My father spends his days off watching television all
> the time.)

where it doubles in using the は particle. From [another
post](https://japanese.stackexchange.com/questions/6366/can-the-
particle-%E3%81%AF-be-used-twice), it seems that this would be a valid
sentence if one of the particles marks the topic, while the other marks a
constrast. Yet in this case, it seems that both particles mark the topic as I
don't believe there is anything obvious to contrast. Would I happen to be
missing something here?

question
particles
Is using the particle は twice here natural?
