Engraving of a watch for Christmas

Hey!

My boyfriend is a native Japanese man and I bought him a nice watch for Christmas which Ifd like to have engraved in the back with something really lovely in Japanese (not kanji preferably). Ifd like something short along the lines of eIfll love you timelesslyf (get it cause itfs a watch? Ha..) or just something really romantic to let him know how much I love him and appreciate him. I know English doesnft translate that well directly in Japanese so Ifd love to know some well known and preferably poetic words I could write in Japanese to express this to him in a way thatfs more special to him.

Thanks in advance!

That might be kind of a difficult combination. Generally speaking, writing in Japanese without using kanji gives the message a childish feel to it. Kanji are, of course, harder to learn than hiragana/katakana, and so writing using only hiragana/katakana is usually done by people who haven't learned many kanji yet, i.e. kids.
