Yes, Sara.  I mean it´s timeless.

Be aware that, timeless can be:

1- adj. remaining beautiful, attractive and not becoming old-fashioned.

2-literary.   continuing for ever, as in 'the timeless universe'.

Source: Collins, with slight rewording that I did.

   As for the 'son of a beach' stuff, you could say 'son of a gun' as well, to avoid

the 'grammatical existential crisis', he he.

    But, son of a beach would be fine (pun intended).
