- Case and Dial Design
- The Quenttin is characterized by its large, rectangular architecture measuring 53 mm by 45 mm and 20 mm in thickness. The case is constructed from magnesium aluminium, featuring a mix of polished and brushed surfaces, complemented by carbon fiber inlays along the sides. Sapphire crystals protect both the dial and the mechanical aperture. The dial configuration departs from traditional analog layouts, utilizing three black vertical disks to display the time and power reserve status. These disks are marked with luminous Arabic numerals, designed for legibility against the dark background.
- Movement and Mechanics
- The watch is driven by the Caliber 5, a movement developed by BNB Concept. The central technical achievement of this caliber is its 31-day power reserve, which is sustained by seven vertically-stacked barrels mounted coaxially. This high-capacity energy system is coupled with a vertical lever escapement, which features a one-minute tourbillon regulator to counteract gravitational effects. The tourbillon carriage, for example, utilizes bearings rather than traditional rollers to minimize friction. The movement contains 40 jewels and is signed, as are the dial and the case, maintaining consistency across the horological components.
- Accessories and Provenance
- This watch, identified as number 10 of the 18 pieces produced in 2007, is provided with a comprehensive set of accessories. These include the original certificate of origin and an instruction booklet. The timepiece is housed in a large, motorized display case designed specifically for this model. The display case incorporates lighting and an automatic winding mechanism, reflecting the intended requirements for maintaining a watch with such an extensive power reserve capacity. The auction description includes a grading system for the object, reporting the movement and dial as 'As new' (Grade 1), while the case is listed as 'Very good' (Grade 2). The watch is accompanied by a transportation bag for the motorized case, ensuring its portability despite the size of the display apparatus.
