Reservoir, a brand renowned for its instrument-inspired timepieces, has introduced its latest Mark II series, showcasing a notable advancement in its design philosophy. This new collection moves beyond just distinctive dial displays, presenting a complete re-imagining of the watch's architecture with a seamlessly integrated case and bracelet. The series embodies a fusion of mechanical inspiration and sophisticated aesthetics, solidifying Reservoir's identity in the luxury watch market.

The Mark II series emphasizes a cohesive design, where the case and bracelet merge into a unified form. This integrated approach, combined with the brand's signature jumping hour and retrograde minute functions, creates a powerful visual and mechanical statement. The collection's release, featuring three distinct models, signifies a new chapter for Reservoir, highlighting their commitment to innovation while honoring their foundational inspiration from automotive, aeronautical, and industrial gauges.

Refined Aesthetics and Integrated Construction

The new Mark II series from Reservoir represents a significant leap in design, moving towards a fully integrated case and bracelet structure. This development goes beyond the brand's previous focus on instrument-inspired dials, creating a cohesive and identifiable overall silhouette. The 41mm stainless steel case showcases a fresh geometric language, characterized by sharp angles, faceted surfaces, and prominent screws, all drawing from the rich aesthetic of mechanical instruments that have long been a source of inspiration for Reservoir. This meticulous construction is further enhanced by a diverse mix of finishes, including satin-brushed and vertically brushed surfaces that offer a compelling contrast with polished bevels, allowing light to interact dynamically and highlight the watch's intricate forms.

This sophisticated design ethos extends seamlessly to the integrated bracelet, which mirrors the case's angular construction and alternating brushed and polished finishes. Every element, down to the crown, folding clasp, and caseback, has been thoughtfully redesigned to align with this new aesthetic, each proudly bearing the brand's emblem. This comprehensive design approach ensures that the Mark II series stands out not only for its unique time display but also for its unified and elegant physical presence. The result is a collection of timepieces that feel both robust and refined, appealing to enthusiasts who appreciate both technical prowess and distinctive visual appeal in their luxury watches.

Signature Time Displays and Advanced Mechanics

While the external design of the Mark II series has undergone a notable transformation, the core philosophy of Reservoir's distinctive time display remains central to these new models. The collection integrates the brand's emblematic jumping hour and retrograde minute mechanisms, along with a power reserve indicator positioned at 6 o'clock. This unique way of telling time is consistent across the three models introduced in the Mark II series: the GT Tour, Kanister, and Airfight Jet, each drawing inspiration from different types of classic measuring instruments, whether automotive, aviation, or industrial.

These watches are powered by the Calibre RSV-240, a sophisticated proprietary complication module with 113 components, developed by movement specialist Telos. This module is expertly paired with a modified La Joux-Perret G100 automatic base movement, ensuring precision and reliability. Operating at a frequency of 28,800 vibrations per hour, the movement provides a substantial 56-hour power reserve. This slightly reduced power reserve, compared to the standard G100, is a result of the energy required by the intricate jumping hour and retrograde minute module. The mechanism is designed for seamless operation: every 60 minutes, the minute hand elegantly sweeps back to its starting position, prompting an instantaneous jump of the hour. This combination of innovative display and robust movement underscores Reservoir's commitment to both unique aesthetics and high-performance horology.
