By wëbuënt?mën I assume you mean wënutëntamën.  This word would work okay:  nepe nutëntamën in SU, if what you are watching over or guarding is something definite that is inanimate ("it").  You could even make the inanimate object indefinite ("something") by saying nepe nutëntam. 

In NU, I would say, nepe n'woachpasimsa; which, by using the archaic imperfect tense (what Goddard calls the present aspect), would more nearly match your English phrasing ("I too, I have kept the watch").  In SU (if it ever existed in SU) it would be written as nëwahpasimsa.

[Note: The forum will not reproduce the SU short a with the grave accent, so I've simply used the plain a in the Lenape words in the first paragraph.]

If you need a definite inanimate object then go with the SU word.  The stem of woachpasimsa is woachpasi- ('keep watch').  It's an intransitive verb, so there is no object. It just means you're engaged in keeping watch.  Stress is on the next-to-last syllable.
