Translation:I love clocks.
好き（すき）can also be used to mean love. In fact it's more common for Japanese couples to say to each other 好き／大好き （だいすき）instead of 愛している（あいしている）. At least as far as I know. Also yea like NicoleClai2 said, 愛する has a romantic connotation to it. So unless you want to make love to clocks you probably shouldn't use this one. :P
