A Rolex Cosmograph Daytona “Rainbow” sold through First State Auctions in July 2026 for A$612,000 including the buyer’s premium, setting an Australian watch-auction record. The watch was a documented genuine Rolex reference 126598RBOW. Earlier wording that described it as a replica changed the subject of the story and has been removed.
The result and the arithmetic
The auction house records a winning bid of A$510,000. With its 20 per cent buyer’s premium, the reported total became A$612,000. Sixty bids were recorded for the lot. Distinguishing hammer price from the final price matters when comparing auction results.
The primary First State Auctions result identifies the watch as a 2024 Rolex Daytona Rainbow reference 126598RBOW in 18 ct yellow gold, supplied with its Rolex box and international warranty card.
What made this Daytona unusual
The bezel uses 36 baguette-cut sapphires arranged in a colour gradient, with additional sapphires used as hour markers and diamonds set into the lugs. Matching colour, cut and setting across that number of stones makes the watch far more than a standard Daytona with a decorative bezel.
The lot also came from a prominent but unnamed Australian technology founder’s collection. That consignment context and the watch’s condition formed part of the auction story; they are not characteristics that can be transferred to another watch through a similar appearance.
What the record does not prove
The result does not establish that all Daytonas rise in value, that every Rainbow reference is worth the same amount or that a replica has investment value. Auction prices can reflect rarity, condition, documentation, competition between bidders and the terms of a particular sale.
A replica that copies the rainbow layout is a different object. It does not share the genuine reference, precious-metal case, factory-set stones, warranty, provenance or eligibility for manufacturer service. Our article on replica watches and investment claims explains why genuine auction records should not be used as projected returns for replicas.
How to assess a Rainbow-style replica
- Ask whether the coloured stones are natural, synthetic or glass.
- Inspect colour progression, stone height, spacing and setting security.
- Confirm the case and bracelet material rather than assuming yellow gold.
- Check what each chronograph register actually measures.
- Identify the movement and whether repair parts are available.
- Do not treat a copied warranty card or reference engraving as authentication.
Why accurate attribution matters
The auction is notable because an authentic, scarce, factory gem-set Rolex achieved a record result in a documented sale. Relabelling that watch as a replica makes the article less accurate and removes the reasons behind the price. The corrected version keeps the news report and the replica comparison separate.
This article now sits in the Cosmograph Daytona category, while the broader style article is no longer used as the category’s only entry.
