Bell & Ross BR-X5 Blue LumvsPagani Design PD-1791

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.

Owners widely find the Pagani Design PD-1791's skeleton dial unattractive, with one owner describing it as "ugly" and another disliking the "circle inside square" aesthetic. Some suggest it would be better suited for modifications. On balance, the consensus is that owners rate the Pagani Design PD-1791 poorly due to its polarizing and widely disliked dial design.
