Rolex Cosmograph Daytona Steel Rolesor - Black 126503

Overview 

The 126503 occupies the Rolesor position in the steel Daytona lineup — Oystersteel case with 18k yellow gold tachymeter bezel, gold sub-dial rings, and gold hour markers. The two-tone configuration has a long history in the Daytona family, traceable to the original yellow gold–bezel references of the Zenith-movement era.

The case is 40mm Oystersteel with an 18k yellow gold tachymeter bezel and polished gold ring at the outer edge. The dial is black with yellow gold sub-dial surrounds, markers, and hands — the gold elements provide warmth against an otherwise dark layout. The Oyster bracelet alternates Oystersteel and yellow gold centre links in the Rolesor format. The combination is less assertive than a full gold Daytona and more visually specific than the all-steel variants.

Calibre 4131, 72-hour power reserve. Same movement specification as all 126500-series Daytonas.

The 126503 is priced below the all-steel white panda 126500LN at current retail and secondary — the Rolesor configuration does not command the demand premium that the white-panda all-steel variant does, which creates an interesting value proposition: a two-tone Daytona with gold bezel and markers at a lower secondary entry than the mono-material steel variant. For buyers who specifically want the Rolesor configuration, we believe this is a fair entry point. This piece is currently sold out, complete with box and papers dated May 2026, at RM113,500.
