Founded by the Netherlands-based brothers Bart and Tim Gronefeld, their eponymous brand carries a legacy of watchmaking that dates back to 1912, bringing a wealth of expertise to each meticulously crafted timepiece. Combining contemporary aesthetics with classical mechanics, Gronefeld’s design language culminates in watches that are not merely timekeepers but wearable pieces of art. Offered here as a very testament to that is the the exquisite Gronefeld 1941 Principia for Sydel and Sydel, a highly coveted edition limited of just 10 pieces exclusively for Sydel and Sydel of Chicago. This remarkable watch boasts a striking two-tone blue dial known as Gröneblue that draws inspiration from an 8-second Remontoire with similar blue-gray hues. The dial showcases a vibrant blue sunburst finish on the outer track and a deeper blue matte finish in the center, this timepiece offers a dynamic interplay of colors that shift from a bright, vibrant blue to a midnight blue in varying lighting conditions. Celebrating Gronefeld’s craftsmanship from outside to inside, the 1941 Principia features an exceptionally well-finished 226-piece movement on display behind its exhibition caseback that showcases the skills the brothers refined during their time at Renaud & Papi.

Watch is in like-new condition, with little to no signs of wear.

Exceptionally rare and truly stunning, the 1941 Principia for Sydel and Sydel showcases Grönefeld's exceptional craftsmanship while maintaining the brand's understated aesthetic and under-the-radar designs.
