# Harry Winston Precious Emerald – A High‑Jewellery Timepiece in Miniature The Harry Winston Precious Emerald is a miniature marvel that sits at the intersection of haute joaillerie and horology. Housed in a 17.5 mm platinum case that echoes the geometry of an emerald‑cut gemstone, the watch is less a conventional chronometer than a wearable piece of art. Its mother‑of‑pearl dial is cradled by a sculptural platinum bracelet set with 126 marquise‑cut diamonds that cascade from the case’s extremities to a discreet clasp. Powered by a Swiss quartz movement (Caliber HW1051), the piece belongs to the brand’s High Jewelry Timepiece collection, a line that treats each model as a jewel first and a timekeeper second. In this review we examine where the Precious Emerald fits within Harry Winston’s heritage, dissect its design and technical underpinnings, and assess how it feels on the wrist and where it belongs in a modern wardrobe. --- ## Heritage — the model's place in the brand's line and its launch context Harry Winston has long been synonymous with extraordinary diamonds and bold, architectural jewellery. The brand’s foray into high‑jewellery timepieces began as an extension of that DNA: watches that are conceived as jewels, with the same meticulous gem‑setting and sculptural sensibility found in its haute couture collections. The Precious Emerald is part of the **High Jewelry Timepiece** collection, a tier‑1 line positioned at the very top of the brand’s offerings. Within this tier, the model is classified as a **dress** watch, meaning it is intended to complement formal attire rather than serve as an all‑day sports companion. The collection’s overarching narrative is rooted in Harry Winston’s fascination with “exceptional diamonds and coloured stones,” and each piece is designed to be a standalone treasure that can also harmonise with the brand’s broader jewellery archives. Although the exact launch year is not disclosed in the available sources, the watch appears alongside other Precious Emerald variants on the brand’s official site, indicating a coordinated release within the collection. The model’s reference number, **HJTQHM18PP009**, follows the brand’s systematic coding that denotes material (platinum), collection (Precious Emerald), and specific configuration. This systematic approach underscores Harry Winston’s intent to treat each watch as a distinct, collectible artefact within its high‑jewellery lineage. --- ## Design & Case — case dimensions, materials, dial ### Case The case measures a modest **17.5 mm** in diameter, a size that places it firmly in the realm of petite luxury watches. Its silhouette is inspired by the **emerald‑cut**—the iconic rectangular shape with beveled corners—translated into an octagonal, sculptural form that feels both modern and timeless. Crafted from **platinum**, the case exudes a muted, luxurious luster that serves as a perfect backdrop for the surrounding diamonds. The **water resistance** rating of **30 m** (3 atm) reflects the watch’s primary function as a decorative piece rather than an adventure‑ready instrument. While sufficient for everyday exposure to rain or hand washing, the limited resistance means the watch should be removed for swimming, diving, or prolonged water exposure. ### Dial The dial is a **mother‑of‑pearl** canvas, its iridescent surface catching light in a subtle, ever‑changing play of colour. The choice of mother‑of‑pearl aligns with the watch’s jewellery‑centric ethos, offering a soft, organic contrast to the hard brilliance of the surrounding diamonds. Hour markers are discreet, allowing the dial’s natural beauty to dominate the visual field. The quartz movement drives a simple, clean hands set that is easy to read despite the small case diameter. ### Bracelet Perhaps the most striking element is the **platinum bracelet**, described as an “artistic masterpiece” that “glows with the light of 126 marquise‑cut diamonds.” The diamonds are set in a flowing pattern that begins at the case’s extremities and continues seamlessly to the clasp, creating a continuous band of sparkle. The bracelet’s design is a reinterpretation of the **Winston Cluster**, a signature motif in the brand’s jewellery, rendered here as a fluid, wearable band. The clasp is discreet, maintaining the piece’s overall elegance while ensuring secure wear. ### Overall Aesthetic The Precious Emerald is unmistakably a **high‑jewellery** creation. Its proportions, materials, and gem‑setting speak to a philosophy where the watch is an extension of a jewellery set, meant to be paired with other Harry Winston pieces. The octagonal case and diamond‑laden bracelet together form a cohesive narrative that celebrates both geometry and natural brilliance. --- ## Movement & Performance — caliber, power reserve, accuracy At the heart of the Precious Emerald lies the **Caliber HW1051**, a Swiss‑made quartz movement. While the source does not detail the movement’s inner architecture, it is identified simply as a **quartz** calibre, indicating that the watch relies on a battery‑powered oscillator rather than a mechanical mainspring. Quartz movements are celebrated for their reliability, low maintenance, and consistent timekeeping under normal conditions. Because the watch is positioned as a high‑jewellery piece, the emphasis is placed on the visual and material qualities rather than on technical horological feats such as extended power reserves or ultra‑high accuracy specifications. No explicit power‑reserve figure is provided, as quartz watches typically run for several years on a single battery. Likewise, there is no documented claim regarding accuracy margins (e.g., ±5 seconds per month), and therefore no such figure is presented. The **30 m water resistance** is a functional limitation inherent to the case construction and the delicate nature of the mother‑of‑pearl dial and extensive diamond setting. The watch is best treated as a dress accessory, with care taken to avoid exposure to moisture beyond everyday splashes. --- ## On the Wrist — wearability, lug‑to‑lug, comfort notes ### Size and Fit With a **17.5 mm** case, the Precious Emerald is decidedly petite, appealing to those who favour a subtle wrist presence or have smaller wrist circumferences. The small diameter ensures that the watch does not dominate the wrist, allowing the bracelet’s diamond‑laden design to take centre stage. The lug‑to‑lug spread is proportionate to the case size, resulting in a balanced silhouette that sits comfortably between the wrist bones without overreaching. ### Bracelet Comfort The bracelet, while visually opulent, is also engineered for wearability. Platinum, though dense, is softened through careful polishing, and the setting of 126 marquise‑cut diamonds is executed with a focus on smoothness to avoid snagging. The “fluid bracelet” design, inspired by the Winston Cluster, distributes weight evenly across the wrist, mitigating the feeling of heaviness that can sometimes accompany high‑jewellery pieces. The clasp’s discreet nature adds to a seamless wearing experience. ### Practical Considerations Because the watch is a quartz‑driven, high‑jewellery piece, it is relatively low‑maintenance from a movement perspective—no winding is required, and the watch will keep time reliably as long as the battery remains functional. However, the extensive diamond setting demands careful handling; the watch should be stored in a soft pouch or a dedicated jewellery box when not worn to protect the gems from scratches or accidental impact. The **30 m water resistance** means that the wearer should avoid submerging the watch, and even prolonged exposure to sweat or humidity could affect the setting over time. Routine professional cleaning by a jeweller familiar with high‑jewellery watches is advisable to maintain the brilliance of the diamonds and the integrity of the mother‑of‑pearl dial. --- ## When to Wear — occasion, setting and dress‑code fit The Precious Emerald is unmistakably a **formal, dress‑code** accessory. Its platinum case, mother‑of‑pearl dial, and diamond‑encrusted bracelet make it a natural companion for black‑tie events, gala evenings, and high‑society functions where jewellery takes a starring role. The watch’s modest case size ensures it does not overwhelm a tuxedo or evening gown, while the sparkling bracelet adds a touch of glamour that can echo the sparkle of a necklace or earrings from the same collection. Because the piece is part of Harry Winston’s high‑jewellery line, it pairs best with other **Harry Winston jewellery**—for instance, a matching diamond necklace or a pair of earrings featuring the same marquise‑cut diamonds. The cohesive aesthetic reinforces the brand’s narrative of “jewels first, timekeepers second,” making the watch a seamless extension of a coordinated jewellery set. In less formal settings—such as business meetings or daytime social gatherings—the watch can still be appropriate, provided the overall attire leans toward the elegant side. A tailored suit or a refined cocktail dress can accommodate the piece without feeling overdressed. However, the watch’s delicate nature and limited water resistance suggest it should be avoided during activities that involve physical exertion, sports, or exposure to harsh environments. --- ## Value & Verdict — price‑positioning + final take ### Price Positioning The source data does not disclose a retail price for the Precious Emerald, and no public pricing information is provided. Consequently, the review refrains from speculative cost assessments. As a **tier‑1, high‑jewellery** watch from a brand renowned for exceptional diamonds, the model is positioned at the premium end of the market, targeting collectors and connoisseurs who value craftsmanship and gem‑setting above conventional watchmaking metrics. ### Verdict The Harry Winston Precious Emerald succeeds admirably in its stated mission: to be a **jewel‑first timepiece** that offers a wearable expression of the brand’s diamond heritage. Its **platinum case** and **octagonal emerald‑cut silhouette** deliver a refined, architectural aesthetic, while the **mother‑of‑pearl dial** adds a subtle, organic glow. The **bracelet**, studded with **126 marquise‑cut diamonds**, is arguably the watch’s most arresting feature, turning the band into a flowing cascade of light that mirrors the iconic Winston Cluster. From a technical standpoint, the **Caliber HW1051 quartz movement** provides dependable timekeeping without the need for regular winding, aligning with the watch’s role as an ornamental piece rather than a horological showcase. The **30 m water resistance** and the delicate nature of the dial and gem‑setting remind the wearer that this is a dress‑watch, best reserved for formal occasions and careful handling. Potential drawbacks include the **very small case size**, which may limit legibility for those accustomed to larger dials, and the **limited water resistance**, restricting everyday utility. Additionally, because the watch relies on a quartz movement, purists who favour mechanical complications may find it less compelling from a horological perspective. Overall, the Precious Emerald is a **masterclass in high‑jewellery watchmaking**—a piece that feels more like a sculptural accessory than a conventional timepiece. For collectors seeking a wearable treasure that can sit alongside a Harry Winston diamond necklace or be displayed as a standalone work of art, the Precious Emerald delivers on both aesthetic ambition and refined execution. Its value lies not in chronometric performance but in the **exquisite craftsmanship, rarity of materials, and the brand’s storied legacy of diamonds**, making it a worthy addition to any serious high‑jewellery watch portfolio.
