Hanhart has long been synonymous with precision, reliability, and a distinct tool-watch sensibility. From its iconic chronographs with the signature red pusher to its sturdy field watches, the brand's heritage is deeply rooted in functional, purpose-driven timepieces. This established identity makes the introduction of the Square by Square a truly unexpected, yet intriguing, development. As detailed by Worn & Wound, this limited edition of six prototypes represents a bold foray into shaped cases and avant-garde design, challenging the market's prevailing focus on sports watches and offering a fresh perspective from the historic German marque.
A Design Born from Collaboration and Competition

The genesis of the Square by Square can be traced back to a collaborative effort with Munich-based designer Marcus Wiedemann, a creative partner with whom Hanhart has previously worked. This partnership culminated in an entry for the prestigious Dubai Watch Week x Grail Watch Design Competition. The design garnered significant recognition, earning a finalist spot in the highly specific category of "Most out-of-the-box, innovative yet viable shaped watch design." This accolade underscores the watch's unique approach and its successful navigation of both creative ambition and manufacturing feasibility.
The core inspiration for the Square by Square extends beyond the brand's extensive archives of shaped watches, delving into abstract scientific and mathematical concepts. Hanhart notes that the design draws heavily from the idea of "curved spacetime" and the intricate geometry of "hyperbolic paraboloids." These complex forms manifest in surfaces that appear to curve both inwards and outwards simultaneously, creating a dynamic and visually captivating effect that defines the watch's aesthetic.
A Study in Geometric Form and Optical Illusion

The case of the Square by Square is perhaps its most distinctive feature. While it initially presents as a square, it is designed to sit on the wrist in a tilted, diamond-like orientation. This unconventional alignment immediately sets it apart. The case itself is a masterclass in subtle curves and contours, with the lugs gently sloping downwards, contributing to an ergonomic profile despite its angular appearance. The interplay of these surfaces, inspired by hyperbolic paraboloids, creates a fascinating visual paradox, where the watch seems to shift and undulate with light and movement.
Central to the Square by Square's unique optical effect is its domed sapphire crystal. According to Hanhart, as reported by Worn & Wound, the manufacturing process for this crystal presented significant challenges during the prototyping phase, involving multiple broken crystals before the correct process was perfected. The crystal extends precisely to the edges of the case, a design choice that is crucial in producing the distinctive visual distortion and depth that defines the watch. This meticulous attention to the crystal's integration is key to achieving the desired aesthetic, making it an integral part of the watch's identity.
Distinct Dial Variants and Refined Details

The Square by Square is offered in two distinct dial variants, each exuding its own character while maintaining a cohesive design language. Both versions feature a deep, saturated blue hue that dominates the dial, providing a rich backdrop for the intricate details. An Art Deco-influenced stepped rehaut frames the dial, adorned with custom-designed numerals that subtly echo the angular shape of the case itself, reinforcing the watch's geometric theme.
Where the two variants diverge is in their interior sections and case finishes. The first option showcases a classic blue sunburst design, offering a radiant, dynamic play of light across its surface. This version is paired with a matte-finished case, which provides a sophisticated contrast to the dial's shimmer. The second variant is perhaps even more visually arresting, featuring a mosaic mother-of-pearl dial. This iridescent material creates a mesmerizing, ever-changing display of colors and patterns. To complement this luxurious dial, the mother-of-pearl version is housed within a polished case, enhancing its elegant and refined appeal.
Technical Specifications and Exclusive Availability

While the Square by Square's design is undeniably its most striking aspect, its technical specifications ensure it remains a capable timepiece. As reported by Worn & Wound, the watch measures 40mm from the 12 o'clock to 6 o'clock positions and 38mm from 9 o'clock to 3 o'clock. The lug-to-lug measurement is listed at a compact 32.8mm, with a case height of 10.9mm. These dimensions, particularly for such an unconventionally shaped watch, suggest a unique wrist presence that would best be understood through personal experience.
Powering the Square by Square is a Sellita SW1000 automatic movement, known for its reliability and precision. This movement provides a practical power reserve of 46 hours, ensuring consistent performance. Furthermore, the case offers a water resistance of 100 meters, adding a layer of durability and versatility to this design-forward piece.
Perhaps the most significant aspect of the Hanhart Square by Square is its extreme exclusivity. This release is strictly limited to just six pieces, which Hanhart explicitly refers to as prototypes. There are three examples of each dial variant available. As reported by Worn & Wound, Hanhart has not yet made a final decision on whether this innovative design concept will eventually lead to a serially produced collection. This prototype status underscores the experimental nature of the release, making these six watches exceptionally rare and potentially highly collectible. The retail price for the Square by Square is listed at EUR 1,890, which includes 19% VAT, as per Worn & Wound's report.
