Unmistakable aesthetics

POWER RESERVE

Back

The POWER RESERVE remains true to the family’s neoclassic style. A display back reveals the spirited beauty of the movement. From the front, Arabic numerals, a crisp minute scale, and the case with its delicate bezel as well as the gracefully tapered lugs project refined elegance.

The sublime, manually crafted hands provide an accurate reading of the time from any angle. Additionally, a two-colour power-reserve indicator tells the owner when the time has come to rewind the movement. It showcases the modernity of this perfectly balanced model.

The novelties

The lineage continues with the POWER RESERVE. The new facets of the calibre 100.2 movement follow the tradition of carefully premeditated progress. Inside the second generation, the newly developed Grossmann balance, the Grossmann winder with pusher, and the power-reserve indicator based on a planetary gearing system come together as an exclusive composition in haute horlogerie. Externally, the POWER RESERVE emphasises the technical perfection of this manually wound watch, and with the pusher below the winding crown for the new handsetting train. As a systematic refinement, the POWER RESERVE visually remains true to its watch family. The slender three-part case with the gracefully elegant bezel puts the focus on the suave face of the watch. The generously dimensioned sapphire-crystal display back, which has an antireflective coating on the inside, reveals the full beauty of the movement of the POWER RESERVE.

The dial

A crisply drawn peripheral scale and pragmatic Arabic numerals grace the solid-silver dial. The face of the new BENU line is enriched with a two-colour power-reserve display, a modern detail that harmoniously complements the time indications and the brand signature.

The winding crown and the pusher

Aestitic and functional: the circumferential groove makes it easy to pull the crown. The pusher for the new handsetting train is set directly below the winding crown.

The hands

The gleaming hands are crafted from stainless steel in a proprietary process. A white HyCeram filling is applied to the small hand openings; it is ground flush with the metal and polished to a high gloss.

The saphhire-crystal

A sapphire-crystal glass protects the dial. It has an antireflective coating on one side to prevent viewdisturbing reflections of incident light. The extra-thick slightly cambered glass has a precision-ground chamfer that refracts the geometry of the succinct minute scale.

The butterfly clasp

The optional available butterfly clasp affords extra protection and remains firmly locked until the lateral safety buttons are pressed. It features an engraved logo and assures a particularly snug fit on the wrist.
