"Widzisz tamten zegarek?"

Translation: Do you see that watch?

[Dbossg]

Does "clock" and "watch" differs in polish?

[Jellei]

Yes, 'clock' = 'zegar' is standing somewhere in your house (or you see it somewhere outside your house), while 'watch' = 'zegarek' is something you carry with yourself.

[HarveyPenf]

Should this not be tamtego? as tego is the accusative form of ten which is the nominitive form? e.g. ten pies & lubię tego psa

[Jellei]

Accusative is the only case where it is important whether a masculine noun is animate or inanimate.

If it's animate, the Accusative form looks the same as the Genitive form. "Lubię tego psa. Nie lubię tego psa."

If it's inanimate, the Accusative form looks the same as the Nominative form. "Ten zegarek. Widzę ten zegarek."

You have to also remember that many food articles, especially fruit and vegetables, are considered grammatically animate, although there isn't really any logic to it.
