Minerva's Crownless Innovations
In 1927, Minerva developed one of the first military watches to include bezel-activated functionality using an indicator, which allowed pilots wearing large gloves to easily set an internal timing ring to measure legs of their flight plan—essential for navigation. Today, bezel-activated functions have become a distinguishing feature for select Minerva timepieces, placing the recognisable fluted bezel into the spotlight both visually and functionally.
After introducing a bezel-activated chronograph through the Minerva Unveiled Timekeeper in 2023, Minerva now unveils its first crownless timepiece: Minerva The Unveiled Crownless, where the bezel becomes responsible for both the manual winding and time-setting functions of the watch.
Calibre M15.08
In order to assign the manual winding and time-setting functions to the bezel, Minerva had to develop an entirely new calibre: the Calibre M15.08, a time-only, manually-wound movement with small-seconds crafted entirely in-house in at the Minerva manufacture in Villeret, Switzerland. The top power reserve is a full 80 hours, which, given the traditional beat rate of 18,000vph (2.5hz), indicates the large mainspring. Composed of 139 components and featuring curvaceous bridges in rhodium-plated German silver decorated with polished bevel edges and abundant Geneva striping, the Calibre M15.08 carries Minerva's classic movement architecture and rigorous hand-finishing.
Precision is attained via a free-sprung balance wheel with an array of finely tuned regulating weights mounted to an in-house hairspring. The regulator takes the signature shape of Minerva's arrow.
The Symmetry of a Crownless Watch
Though offered at a modern 41.5mm diameter, Minerva The Unveiled Crownless evokes the meticulous handcraft of Minerva's earliest wristwatches dating back to the 1920s, a manufacturing tradition carried on today in the same building in Villeret, Switzerland. The timepiece comes presented in a stainless steel and 18K rose gold case that possesses an especially strong symmetry due to its lack of a traditional crown. Measuring 12mm tall, including the 18K rose gold fluted bezel and crystal, the watch offers traditional dress-watch proportions. Chamfered lugs reach downward for a comfortable fit on any wrist, while the fully polished surfaces meet to form precision contours that spell out the subtle curvature of the lugs as they meet the dark green alligator strap with semi-matte finish. A new deployant clasp featuring the Minerva arrow emblem includes a fine adjustment system for convenient sizing.
The dial of Minerva The Unveiled Crownless echoes the design of a 1950s Minerva timepiece, masterfully reinterpreting its colourway alongside its guilloché engraving and opaline textures. In its configuration, the dial emphasises the poise of the crownless case, with the inset small-seconds at 6 o'clock visually counterbalancing the vintage Minerva logo and rose-gold-coated Arabic numeral '12' above. The opaline-textured center dial is set into an outer ring of guilloché engraving onto which the faceted hour markers are applied. These indices are tonally matched by the rose-gold coated beveled hands, a nameplate “Villeret 1858” on the mid-case, and, of course, the signature fluted bezel.
The Crownless Case
The sapphire caseback allows a clear view of the highly decorated Calibre M15.08. On the 3 o'clock side of the caseback's stainless steel frame is a lever for switching the bezel's function between winding the movement (lever in) to time-setting (lever extended). Because this lever is discretely concealed in the case-back ring, the harmony of the crownless case stays visually balanced.
Minerva The Unveiled Crownless remains rooted in Minerva's legacy while also displaying the manufacture's ongoing dedication to watchmaking innovation at the highest level.
Packaging
Minerva The Unveiled Crownless is presented in a new box crafted entirely in Switzerland by expert woodworkers. A secret opening system makes for a clean appearance as well as an engaging experience for the owner.
The box's elegant natural walnut-veneer is topped with a stainless steel plate with a special engraving of the Minerva manufacture in Villeret, Switzerland, where it has stood since 1858. The VRF logo with the Minerva arrow, one of Minerva’s signatures, is also included here. Standing for Robert Frères Villeret, the logo had been used on watch cases and movements up into the early 20th century. The location of Villeret is also expressed on the latch, which includes an engraving of the village’s coat of arms. Inside the box is a generous padded storage compartment for the watch along with a loupe magnifier which also carries the Minerva logo, this tool allowing the owner to explore the watch in great detail.
