Introducing MB&F Special Projects (ref. SP1.RL.B), a refined timepiece that blends thoughtful design with reliable performance. A study in proportion and durability: crafted in red gold and measuring 38 mm in diameter, with a thickness of 12 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 3000 meters. The dial composition is deliberate and legible: a black tone with sunburst finish, framed by stick / dot hour markers, and dauphine hands. Beneath the caseback lies dependable performance: the SP One caliber. Introduced in 2025. Comfort and balance define the wearing experience, making it an easy daily companion. Subtle transitions between textures elevate the overall impression. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
