Design

Case and Design
The MB&F SP One is constructed with a platinum case measuring 38 mm in diameter. According to the provided information, this model represents the first special project from the brand to employ a platinum case. The design is characterized by a minimalist approach intended to prioritize the internal mechanical arrangement over a larger case structure. The watch departs from the brand’s larger designs, featuring a more classical and slender profile. The case is designed to house a proprietary caliber and provides a view of the internal assembly through its structure. The overall design language focuses on the presentation of the movement as the focal point.
Visible features
• Y-shaped bridge supporting the movement components • Inclined black dial displaying hours and minutes • Exposed balance wheel and barrel assembly within the case perimeter • Platinum case with polished finish
Movement and Architecture
The movement is composed of 189 individual parts. Its construction centers on a Y-shaped bridge, which serves to hold the key functional elements of the movement, including the barrel and the balance wheel, in a circular arrangement. The layout incorporates an inclined dial which is mounted on a stepped, sloped edge. Maximillian Büsser refers to this configuration as an amphitheatre structure. This arrangement is designed to expose the moving mechanical parts, ensuring they remain visible and structurally balanced within the case.
Technical Status and Provenance
The initial design concepts for the SP One were developed by Maximillian Büsser in 2018. The model is described as a representation of the brand’s philosophy, focusing on the mechanical display of the watch without extraneous elements. Technical details regarding the current functional state or service history of the watch are not provided. The information is based on specifications from the manufacturer and other listed sources. It is noted that independent verification of the movement's technical condition or authenticity has not been conducted by the documenting entity.
