What people say

Owners + reviewers, side by side

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

Bell & Ross BR-X5 Blue Lum

The Bell & Ross BR-X5 Blue Lum features a composite case with blue luminescent quartz fibre and titanium, and its dial, indices, hands, and power reserve indicator are treated with blue Super-LumiNova. The watch is powered by the Kenissi-manufactured Caliber BR-CAL.323 automatic movement, which provides a 70-hour power reserve. The luminous composite case components appear a pale blue in daylight and emit a bright aqua blue glow in the dark, though the date numerals are unlit. On balance, reviewers highlight the BR-X5 Blue Lum's distinctive luminous case and dial as its primary appeal.

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.
