Looking in all the Catalogs, I can not find a Sea Dragon Zodiac watch.
Was there such a flavor vintage Zodiac?   :godfather;

On another note, the catalogs saved me today from buying a too small Zodiac for my wife.
The numbers on the back of the 90's Zodiacs really help to know the size and the one dual tone
Sea Wolf silver point was the smallest version, I was looking for the larger women's model.

The "sea Dragon" line  was introduced after the Fossil take over.

Iktomi is correct and that is because Fossil lost the rights, or never had them world wide may be a better way to say it, to the Sea Wolf model name, in one word or two. Hence the Sea Dragon.
