Oris Big Crown Calibre 113vsBell & Ross BR-X5 Blue Lum

The Oris Big Crown Calibre 113 is noted for its distinctive mint green and rose pink dial, a 43mm stainless steel case, and an in-house hand-wound movement offering a 10-day power reserve. It includes a business calendar complication, day, date, and a non-linear power reserve indicator, with excellent readability provided by Super-LumiNova. One reviewer found the bold dial color potentially clashes with a business context and wished for a smaller case size. The Oris Big Crown Calibre 113 is priced at CHF 6,350 / €6,350 and includes a five-year warranty. Overall, reviewers highlight the Oris Big Crown Calibre 113's unique dial and extensive complications as its primary draw.

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.
