The Mazzo Spider Diver is a one-of-one statement: a deliberate collision of raw mechanics and refined finishing. At its heart sits the rare ETA Unitas 6497-2 (BL109) Spider Skeleton, exposed to reveal the movement’s architecture and the subtle artistry of its skeletonized bridges. Each variant is distinguished by its distinct stone color. A single movement exists for each color, making every watch a unique collectible.

Encased in a striking 50 mm XL diver case, this piece combines presence with purpose. Super-LumiNova C1 hands ensure legibility in low light, while the genuine calfskin strap balances the case’s scale with refined wearability. Every component is selected for character and durability, then assembled, engraved, and hand-regulated in Canada to Mazzo’s precision standards.

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, it embodies both mechanical honesty and artisanal care.

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.
