«We had a dream from the very first day in our journey: to create a watch belonging to our identity, by designing our own movement, made in Italy, and a timepiece that would be its most coherent expression. It seemed like a utopia, before we met Fausto Berizzi, a historic figure in Italian watchmaking. Together, we brought the V5000 to life: our first caliber designed and built in Italy. Today, that dream takes shape in the Redentore Utopia. It’s a milestone — but for us, it’s only the beginning.»
Cal. V5000
The V5000 is our first proprietary mechanical movement, designed and manufactured in Italy. It offers a 60-hour power reserve within a remarkably slim 3.5 mm profile, and an accuracy of ±3 seconds per day. It features a variable-inertia balance wheel made of copper-beryllium with four masselottes, a dual-anchored balance bridge, KIF Elastor shock protection system, and anti-loosening screws. Every detail is finished by hand with artisanal care, including radial Côtes de Genève, polished anglage, and micro-perlage.

The Expertise of Berizzi, Technical Director at OISA
Crafted by Atokalpa from a copper-beryllium alloy, this balance wheel is regulated using four masselottes — small peripheral weights that allow the inertia to be adjusted without changing the active length of the hairspring. Compared to traditional balance wheels with a regulator index, the variable inertia system enables more precise and stable regulation over time, minimizing the impact of shocks or positional changes on the watch’s accuracy. This type of balance wheel is typical of haute horlogerie, where long-term chronometric performance is a top priority.
In this system, the transmission of motion is divided into two separate branches: one dedicated to the seconds, the other to hours and minutes. This mechanical separation reduces interference between the gear trains, preventing the continuous motion of the seconds hand from affecting the consistency of the main timekeeping system. The result is greater running stability and more reliable long-term accuracy. A refined approach to movement construction, designed with precision as its highest priority.
KIF Parechoc is a Swiss company specializing in shock protection systems for mechanical movements. In V5000 caliber, we use the KIF Elastor, designed to safeguard the balance against sudden impacts. A star-shaped helical spring, placed around the jewel setting, absorbs the shock’s energy and get back the balance wheel to its optimal position. This compact system offers greater precision and stability compared to simpler alternatives, enhancing the movement’s durability even under dynamic conditions.
Carefully engineered to balance efficiency and practicality, the V5000 is featured by a 60-hours power reserve — well above the average for mechanical movements. This relevant interval allows the watch to maintain stable and accurate timekeeping even after several days of rest, eliminating the need for unnecessary adjustments or winding. It’s a power reserve designed to naturally adapt to different wearing habits, whether used daily or rotated with other timepieces, always ensuring readiness and consistent performance.

Step 1
CNC machining
Every structural component of the V5000 is crafted from solid brass blocks using high-precision CNC machines. This process allows for the creation of complex geometries and micrometric tolerances, ensuring uniformity and robustness across every part of the movement. Milling begins with raw plates, which are gradually sculpted to reveal the final shape of each component—bridges, mainplates, and more. The quality of this method is evident in the details: crisp surfaces, perfectly aligned holes, and three-dimensional profiles executed with technical precision.
Step 2
Application of Radial Côtes de Genève Finishing
After mechanical machining, each bridge of the V5000 calibre is finished with a radial Côtes de Genève decoration. This technique demands exceptional precision: the optical effect is created by engraving fine, undulating lines in a regular sequence, radiating outward from a central point. Unlike the more common linear finish, the radial pattern requires constant adjustment of the tool and perfect alignment between the surface and its rotating movement. The result is a luminous, dynamic texture that catches the light and enhances the movement’s architecture.
Step 3
Micro-Perlage Applied to the Mainplate
The micro-perlage decoration is hand-applied to the section of the mainplate located beneath the balance wheel—one of the most sensitive and technically crucial areas of the movement. Each circular pattern is engraved individually using a rotating tool, following an overlapping layout that demands steady control, patience, and consistency. This artisanal finishing, performed by skilled craftsmen, not only enriches the surface with a deep, shimmering texture, but also serves a functional purpose: helping to trap micro-particles and protect the movement from potential impurities.
Step 4
Chemical Nickel Plating
The components of the V5000 caliber passed through chemical nickel plating—a finish chosen both for its technical advantages and its aesthetic alignment with the character of the movement. Compared to rhodium, which has a cooler, bluish reflection, chemical nickel offers a warmer, more neutral tone with a softer, less reflective appearance. Beyond aesthetics, this treatment enhances wear resistance and provides long-lasting protection against oxidation, all without affecting the precise tolerances of each part. After plating, every single component is manually inspected to ensure both visual and functional quality before assembly.
Step 5
Assembly and Regulation
Each V5000 caliber is assembled by hand by master watchmakers in controlled environments using high-precision instruments. This phase demands absolute focus: every component—from the balance wheel to the gear train—is positioned with meticulous care to ensure flawless operation. Once assembly is complete, the movement is finely regulated. Using optical tools and specialized testing equipment, each caliber is calibrated to achieve stable performance within a tolerance of ±3 seconds per day.
The First Model with the V5000
Redentore Utopia is the first model to feature our proprietary V5000 caliber, entirely designed and manufactured in Italy. A timepiece that combines essential design, refined artisanal craftsmanship, and a new vision for Italian mechanical watchmaking. A true turning point in our journey.
