Sartory Billard x Studio Underd0g SB05 Sunfl0wer: A Limited Edition Marvel
The collaboration between Sartory Billard and Studio Underd0g introduces the SB05 Sunfl0wer, a limited-edition timepiece that brings together precise craftsmanship and an artistic approach to dial design. Limited to only ten pieces, this model stands out for its unique dial execution and technical refinements.
Case Construction and Design
The SB05 Sunfl0wer features a 38.5mm stainless steel case with an ultra-slim 8.5mm profile, balancing elegance with modernity. The case is crafted by Voutilainen & Cattin SA, a renowned case manufacturer, ensuring high-quality construction. The concave, polished bezel contrasts with the media-blasted case flanks, creating a refined visual effect. The short, curved lugs are brushed and feature polished bevels, adding complexity to the overall aesthetic. With its curvy design, the case presents a sophisticated yet contemporary silhouette that blends traditional craftsmanship with modern sensibilities.
Dial Execution and Materials
One of the defining aspects of this timepiece is its sunflower-inspired dial, designed by Studio Underd0g and meticulously executed by Sartory Billard. The dial showcases a grand-grain guilloché pattern, forming a sunflower motif with a brown central area that mimics sunflower seeds and a golden outer section engraved with 24 petals. Adding to the depth and complexity, the hour markers and minute track are applied on a floating sapphire disk, which appears suspended above the main dial components. Sartory Billard’s signature Y-shaped design elements are subtly integrated into the guilloché pattern, reinforcing the brand’s distinct aesthetic. The two-piece hour and minute hands feature a green base with a silver upper portion, harmonizing with the small seconds sub-dial and branding tags. Completing the ensemble, the watch is paired with a green Epsom calfskin strap from The Strap Tailor, which enhances the overall visual appeal.
Movement and Performance
The SB05 Sunfl0wer is powered by the SMB01 caliber, a manual-winding movement based on the La Joux-Perret 7380, developed exclusively for Sartory Billard. This movement offers a 90-hour power reserve, ensuring long-lasting performance, and operates at a frequency of 21,600 vibrations per hour (vph), providing smooth functionality. Equipped with 21 jewels, the movement reduces friction and enhances durability. The finishing details are equally impressive, featuring circular satin-brushed upper plates with a gray NAC treatment, polished screws and beveled edges, and radially satin-brushed wheels that contribute to its refined appearance. The sapphire caseback allows for an unobstructed view of this meticulously decorated movement, emphasizing Sartory Billard’s dedication to technical excellence.
