FS: 1950s Sea Wolf prototype ref. 691 before Zodiac named it

Ultra-rare very first Zodiac Sea Wolf prototype without Sea Wolf on the dial. A must-have talking piece for a Zodiac collector and especially anyone into the Zodiac Sea Wolf series. With the first reference 691 screw-back case. Automatic 10ATM diver from my private collection. Unique count-up bezel that turns as it should. Comes on what may be its original unsigned JB Champion USA ratchet-clasp bracelet. Features a unique Zodiac signed AS1361 movement. Considered one of the most collectible Sea Wolf models and rarely seen available for sale in this condition.

Many more photos available on request. Email inquiries to
