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.

Orient M-Force AC0N

Reviewers and owners consistently flag excellent lume and a superior diver bezel, though one owner notes poor low-light legibility due to weak lume. Accuracy figures vary, with one owner reporting stable +12 seconds/day timekeeping while another found it kept near-perfect time when fully wound; a wobbly crown was also noted by one owner.
