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.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
