Presented here is Zodiac Sea Wolf as stated in the Title.
Overall good used condition. Dial, case and crystal are in very good state.
Works. Crown unscrews, watch winds, hands set and date quick set performs nice and easy.
Service history is unknown though. Internal side of the case back bears markings "Feb 2008" (see pictures). Likely it is the date of last service.
I noticed only one imperfection: the bezel is worn and turns easily which, on my opinion, should be turned with some struggle.
Original Zodiac bracelet.
Asking $250 shipped with in Con US and Canada, OBO. Prefer PayPal (have confirmed PayPal address).
Thank you for attention. :pimp;

 crown is original?

Don't know. Attaching the picture. Let me know if more pictures from other perspective are needed.
