What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Zelos Hammerhead (Tantalum LE)

The Zelos Hammerhead (Tantalum LE) features a forged carbon dial and bezel insert with infused lume. On balance, owners and reviewers rate the Zelos Hammerhead (Tantalum LE) highly for its unique material composition and substantial feel.

Studio Underd0g Project Passion Crew

The Studio Underd0g Project Passion Crew is noted for its unique "coarse dégradé amber and royal purple" multi-layer dial and manual-wind Sellita SW510 M chronograph movement with a 63-hour power reserve. However, its accessibility is severely limited as it is only sold as a $64,900 set with another watch. Overall, reviewers highlight the distinctive dial and chronograph movement as key features, though the high price and bundled sale significantly restrict its availability.
