The Spider Classic embodies mechanical purity with sculptural restraint. Built around the rare ETA Unitas 6497-2 (BL109) Spider Skeleton, its bridges are adorned with stones that highlight every gear and spring of the legendary hand-wound caliber. The polished stainless-steel case and dark leather strap bring modern elegance to the raw, industrial core within.

Encased in a 42 mm in-house polished stainless-steel body, the Spider Classic reflects a balance of refinement and strength. Its rounded silhouette contrasts elegantly with the angular geometry of the skeletonized bridges beneath the sapphire crystal, allowing light to flow through every mechanical layer. The black crocodile-pattern calfskin strap anchors the composition with quiet sophistication, emphasizing its modern classic character.

This is not a production model. It is an individual work: one movement per stone colour, one finish, three configuration available to choose. Your purchase includes a signed Certificate of Uniqueness, a 5-year Mazzo Warranty Card, and our signature presentation box with protective travel case. Because each Spider Diver is assembled and regulated by hand.

This model belongs to Mazzo’s exclusive Spider Series, where every movement exists only once per stone color. The first configuration sold, whether Diver or Classic, becomes the definitive edition; all other builds of that color are immediately retired.
