In the world of independent watchmaking, few names resonate with the same reverence as Grönefeld. Brothers Bart and Tim Grönefeld have carved out a distinguished niche, celebrated for their meticulous craftsmanship and innovative complications. Yet, their journey extends beyond the exclusive confines of haute horlogerie. With the introduction of GRØNE Oldenzaal, the brothers have opened a new avenue, offering a distinct expression of their watchmaking philosophy that is both more accessible and deeply personal. This initiative, launched in the fall of 2024, represents a thoughtful expansion, allowing a broader audience to connect with the Grönefeld legacy, which is rooted in their Dutch hometown of Oldenzaal.
The Grönefeld Legacy: From Oldenzaal to Haute Horlogerie

The story of Bart and Tim Grönefeld is inextricably linked to Oldenzaal, a city in the eastern province of Overijssel, Netherlands. Their family's watchmaking heritage spans over a century, with foundations laid in 1912 by their grandfather, Johan Grönefeld. As the third generation to carry this torch, Bart and Tim have always felt a profound connection to their origins. After years of honing their skills abroad, they returned to Oldenzaal, driven by a desire to bring watchmaking back to their ancestral home. As Bart Grönefeld himself articulated, “We are proud of where we come from. It’s quite rare that you can find a watchmaker here in the Netherlands.” This sentiment underscores not just a geographical pride, but a dedication to preserving and evolving a unique craft within their community. While Oldenzaal may not possess the horological renown of Geneva, it holds a deeper, more personal significance for the brothers, enriching the narrative of every timepiece they create.
The Genesis of GRØNE: A New Chapter in Accessibility

The creation of the GRØNE brand emerged during a period when many high-end watchmakers explored diffusion lines, aiming to make their distinctive design languages more accessible. For Bart and Tim Grönefeld, GRØNE is more than just a commercial venture; it is a project they approach with seriousness and, as some observe, a labor of love. It allows them to share their passion and design sensibilities with friends, family, and enthusiasts who might find their largely handmade, high-luxury Grönefeld atelier pieces beyond reach. This accessible line is a deliberate effort to distill their unique aesthetic into products that, while distinct from their bespoke creations, still embody the spirit and personality of the Grönefeld brothers. It represents a commitment to broadening the reach of their watchmaking artistry, ensuring that their heritage and contemporary vision can be appreciated by a wider community.
Distilling Design: GRØNE vs. Grönefeld Atelier

It is crucial to understand the distinction between the Grönefeld atelier and the GRØNE Oldenzaal brand. The Grönefeld name, without the umlaut and with the full spelling, refers to their haute horlogerie creations—pieces known for their intricate, often handmade feel and complex movements, typically accompanied by years-long waitlists. These watches represent the pinnacle of their artisanal craft, where every component is meticulously finished to exacting standards. In contrast, GRØNE Oldenzaal is designed to be more approachable. While it does not aim to replicate the handmade intricacy of their atelier pieces, it successfully captures the aesthetic cues and unique design language that define the Grönefeld brothers' work. The GRØNE line serves as a testament to their ability to translate their sophisticated design philosophy into a more widely available format, offering a different, yet equally compelling, expression of their watchmaking identity. It's a thoughtful balance between exclusivity and broader engagement, allowing their signature style to reach a new audience.
The Horologium: A Showcase of GRØNE's Evolution
The latest offering from GRØNE Oldenzaal, the Horologium, stands as a prime example of this distilled design philosophy. As Man of the Hour previously reported, the Horologium is a new three-hand timepiece that effectively captures the aesthetic cues of the Grönefeld brand while also showcasing the distinct personalities of Bart and Tim. It represents a refinement in GRØNE's design evolution, building upon previous efforts to present a cohesive and engaging collection.
The Horologium's Distinct Personalities: "Quirky" and "Classic"

The Horologium is presented in two distinct variants: “Quirky” and “Classic,” each reflecting a different facet of the brothers' character. The “Quirky” variant features a vibrant bright orange dial complemented by baby blue accents, a nod to the brand’s Dutch heritage. Adding a personal touch, the inside of its caseback crystal is printed with the Dutch phrase “Zoals het klokje thuis tikt, tikt het nergens,” which translates to “home sweet home.” For those who prefer a more understated elegance, the “Classic” variant offers a refined salmon dial with a sunray finishing, presented without any text on the crystal. Both versions share common design elements, including diamond-cut and polished applied hour markers, and a multi-layer dial construction that incorporates a bowled subsidiary seconds display at 6 o'clock, adding depth and visual interest.
Crafting the Horologium: Case and Dial Details

The case of the Horologium measures 39mm in diameter and 10mm thick, a size chosen for its versatility and wearability. For this release, the case has undergone subtle refinements from previous GRØNE designs. The caseband now features a satin brushed finish, which the brand states creates an illusion of thinness, enhancing its elegant profile. Furthermore, the lugs have been slightly redesigned with a more pronounced downturned angle, a deliberate choice to improve the watch's ergonomic fit on the wrist. These thoughtful adjustments underscore the brand's commitment to both aesthetic appeal and practical comfort, ensuring the Horologium is a pleasure to wear.
The Heart of the Horologium: A Custom-Finished Caliber

For the first time in a time-only GRØNE piece, the Horologium features a display caseback, offering a view into its mechanical heart. Powering the watch is a manually wound La Joux-Perret caliber, which has received a surprising amount of custom finishing for this execution. Enthusiasts will appreciate the intricate details, including sunburst snailing, blued screws, machine anglage, and a combination of surface treatments such as sandblasting and mirror polishing. Both the “Quirky” and “Classic” variants also incorporate a visible orange gasket on the caseback crystal, a subtle yet distinctive touch. Each Horologium variant is limited to 188 pieces, with a retail price of €2,390, excluding taxes and shipping, making it a carefully considered offering within the accessible luxury segment. Delivery for these limited editions is expected in September.
The GRØNE Oldenzaal line, and the Horologium within it, stands as a testament to Bart and Tim Grönefeld's enduring passion for watchmaking. It is a bridge between their celebrated haute horlogerie and a broader audience, embodying their unique design language and the rich heritage of their Oldenzaal roots.
