Unworn Harry Winston Midnight Big Date Automatic 18K Rose Gold — Black Dial, Box & Papers, Under Warranty (Ref. MIDABD42RR002)
Harry Winston bought the Hope Diamond in 1949 and gave it to the Smithsonian in 1958. Forty years after that purchase, the company that bore his name decided it was ready to make its own watches. The results have never been ordinary.
Available now at Black Tag Watches (Aventura, Florida), this unworn example — reference MIDABD42RR002 — is cased in 18K rose gold, powered by the 72-hour calibre HW1018, and offered complete with its original Harry Winston box, warranty card, and full delivery accessories dated 2026, remaining under factory warranty.
What Is the Harry Winston Midnight Big Date?
A Jeweller's House That Earned Its Watchmaking Legitimacy
Harry Winston is not, at its foundation, a watchmaker. Harry Winston (1896–1978) founded the eponymous company in New York in 1932 and spent the following four and a half decades handling some of the most significant gemstones of the twentieth century — the Jonker Diamond in 1935, the Hope Diamond in 1949, the Taylor-Burton, the Idol’s Eye, hundreds of stones passing through the Fifth Avenue salon. His nickname was the King of Diamonds, and his innovation was as much cultural as gemmological: he was the first jeweller to lend jewellery to an actress for the Academy Awards, in 1943. The house entered watchmaking in 1989 — deliberately late, deliberately ambitious, and structured from the outset to bring jewellery-atelier discipline to the case, dial, and finishing rather than to compete with the established Genevan houses on movement heritage. The Midnight collection is the modern mainline extension of that argument.
Why This Unworn Full-Set Example Matters
This is the unworn, current-catalogue configuration of the Midnight Big Date, offered with complete original delivery dated 2026 and active factory warranty. For a buyer, that position carries specific weight: Harry Winston boutiques and service centres continue to service the reference under the standard programme, and the 2026 warranty date carries forward from the original delivery. An unworn example with full box, papers, and active warranty is the strongest possible provenance and after-sales-service position a pre-owned Midnight Big Date can occupy — and the version of the reference that requires the least due diligence from the buyer.
Case & Dial Design: Fifth Avenue Architecture, Offset Black Dial
The Three-Rectangle Case Signature
The 42mm case is rendered in polished 18K rose gold, standing 10.7mm thick, with lug and case geometry that reads as intentionally architectural. The three-rectangle bezel and lug motifs found across the Harry Winston catalogue are a direct citation of the façade of the maison’s Fifth Avenue boutique, opened in 1960 — a design signature that ties the watch to the house’s retail identity rather than to a watchmaking convention. The signature emerald-cut motif — Harry Winston’s own favourite diamond cut, and part of the brand’s identity system — appears in the case work.
The Offset Black Dial as an Object
The dial is the reference’s argument, and Harry Winston treats it as an object rather than as an instrument surface. The main time display sits offset to the top of the dial, rendered in a two-tone black composition with rose-gold hour indices, small Arabic numerals in outline form, and slim rose-gold hands. A magnified date aperture at the bottom of the dial — the reference’s namesake feature — displays the date in large-format double digits through a rounded window that reads as a second, complementary dial rather than a conventional aperture. A subtle diamond set beneath the six o’clock marker is the only external decoration. The composition is jewellery-house rather than watchmaker-house — and deliberately so.
Movement: Harry Winston Calibre HW1018 — 72-Hour Automatic
A Three-Day Reserve That Justifies the Price Band
Inside is the Harry Winston calibre HW1018 — a Swiss automatic movement of 35 jewels with a 72-hour power reserve, a specification that meaningfully separates the reference from mid-tier competition, most of which runs at 40 to 48 hours. The three-day reserve is the specification that most cleanly justifies the reference’s price band: a watch that keeps running through a weekend off the wrist behaves the way a dress reference should, staying set rather than restarting from cold each time it is worn.
The Geneva Manufacture and Swatch Group Infrastructure
The HW1018 is produced for Harry Winston at the maison’s Geneva manufacture, opened in 2007 to consolidate the watch operation’s technical infrastructure. Under Swatch Group ownership since 2013, the watch business benefits from access to ETA-family movement architecture and Swatch’s supply chain — but the calibres carrying the HW designation are specifically configured for Harry Winston, with proprietary bridge geometry and finishing to the maison’s Geneva-atelier standards: Côtes de Genève on the bridges, perlage on the mainplate, and a signed oscillating weight visible through the sapphire display caseback. The movement is a genuine manufacture-configured calibre, not a stock ébauche cased unchanged.

Why Buy the Unworn Harry Winston Midnight Big Date?
Watchmaking Legitimacy Earned Across Three Phases
The Midnight Big Date is easy to underestimate if Harry Winston reads as a jewellery house that happens to sell watches. That reading is out of date. The maison’s watchmaking legitimacy has been earned across three specific phases: the 1989 launch, which included the world’s first double-retrograde perpetual calendar; the Opus series (2001–2015), which commissioned annual collaborations with independent watchmakers of the calibre of F.P. Journe, Christophe Claret, Vianney Halter, and Greubel Forsey — and was originally managed by Max Büsser before he left to found MB&F; and the Geneva manufacture opened in 2007 under the maison’s own operational control. The Midnight collection is the mainline everyday-luxury dress line that those deeper Opus and Histoire de Tourbillon experiments existed to give a foundation to.
Current-Catalogue Access, Below Retail, Fully Documented
Against contemporary rose-gold dress watch retail — and against the current Harry Winston catalogue on the Midnight Big Date reference — this unworn example with active factory warranty offers direct current-catalogue access to one of the more architecturally distinctive dress watches in the modern haute-horlogerie market, at a level that rewards horological literacy over badge recognition. For the collector who reads Harry Winston’s Geneva operation as a substantive watchmaking ambition rather than a jewellery-house side project, an unworn full-set example under warranty is the cleanest way to acquire the reference.
