Quiet Elegance, Redefined: Minase Unveils the Mastercraft J3 at Geneva Watch Days 2026

Quiet Elegance, Redefined: Minase Unveils the Mastercraft J3 at Geneva Watch Days 2026

An Ode to Ultimate Simplicity and Japanese Craftsmanship

In the quiet universe of high horology, true luxury often speaks in a whisper rather than a shout. This August, Japanese boutique manufacture Minase unveils its latest creation, the Mastercraft J3, set to make its official debut at Geneva Watch Days at the Beau-Rivage Palace.

Drawing inspiration from the iconic M3 series, internationally celebrated through special editions like the M3 Nori, the Mastercraft J3 pays homage to Minase’s origins while introducing a fresh, modern aesthetic. It represents a subtle, poetic dialogue between timeless Japanese artisanal tradition and contemporary lifestyle requirements.

Refined Dimensions and Micro-Artisanal Sallaz Polishing

To achieve a silhouette that feels like a natural extension of the wrist, Minase has thoughtfully refined the timepiece’s proportions. The Mastercraft J3 features a versatile 37.0 mm cushion-shaped case with an ultra-slim 9.9 mm profile, offering a unisex design suited for both his and her wardrobes.

At the heart of Minase’s design philosophy is an unwavering dedication to hand-finishing. Each steel surface of the J3 is painstakingly hand-polished using the ancient Sallaz polishing technique. This rare artisanal method yields mirror-like, distortion-free surfaces juxtaposed with razor-sharp edges, catching the light in a delicate dance of highlights and soft shadows.

Light Sand Dials and Japanese Heartbeat

The dial of the Mastercraft J3 acts as a canvas of subtle texture and depth. Offered in three classic colorways, White, Beige, and Black, the light-sand finished dials interact gracefully with ambient lighting. Sharp-cut luminescent hands and indexes ensure optimal readability, bathing the dial in a gentle blue glow after dusk.

Marking a historic milestone for the brand, the J3 is the first Minase line to feature a high-grade Japanese movement: the MIYOTA 90S5 automatic caliber. Boasting a 28,800 VPH (4Hz) frequency and a 42-hour power reserve, this reliable engine reflects Minase’s commitment to delivering accessible, authentic Japanese mechanical craftsmanship.

Personalized Versatility for the Modern Collector

Designed for effortless adaptability, the Mastercraft J3 incorporates a one-touch quick-change strap mechanism. Wearers can effortlessly customize their look across a range of options:

  • Classic Stainless Steel Bracelet
  • Crocodile-Embossed Calf Leather Straps
  • Versatile Rubber Straps
  • Smooth Calf Leather Straps

Illuminated Elegance: Discover the Frederique Constant Classics Moneta Solarmetre

By
Illuminated Elegance: Discover the Frederique Constant Classics Moneta Solarmetre

The pursuit of an inexhaustible energy source has accompanied watchmaking for centuries. While traditional mechanical watchmaking continues to refine the autonomy of its movements, modern innovation presents an elegant alternative. Frederique Constant, staying true to its philosophy of accessible luxury, proudly unveils the Classics Moneta Solarmetre, a timepiece where classic aesthetic codes gracefully conceal cutting-edge solar technology.

The Seamless Integration of Solar Innovation

At the heart of the new Classics Moneta Solarmetre beats the pioneering FC-120 solar calibre, meticulously developed in collaboration with the renowned Manufacture La Joux-Perret. While photovoltaic energy is not a novel concept in the industry, its application has historically compromised design due to the visual impact of solar cells.

Frederique Constant has masterfully overcome this hurdle. The architecture of the dial is constructed in three ingenious layers:

  • The visual dial: Appears entirely opaque but is microscopically permeable to light.

  • The solar layer: Houses the photovoltaic cells situated on the second tier.

  • The movement: The remarkably slim FC-120 caliber houses a rechargeable battery capable of converting and storing light as electrical energy.

As long as there is light, the watch continues to run. Even in complete darkness, the Classics Moneta Solarmetre retains an astonishing power reserve of up to ten months.

Aesthetic Harmony: The Coin-Edged Masterpiece

The Solarmetre inherits the collection’s hallmark: a beautifully fluted inner bezel inspired by the ridged profile of antique coins. This new iteration introduces a refined 39 mm polished stainless-steel case, beautifully proportioned with a slender thickness of just 8.52 mm. The sophisticated grained finish on the dial, a first for the collection, adds exceptional depth.

Versatility for the Modern Luxury Consumer

Understanding the dynamic lifestyle of today’s clientele, Frederique Constant delivers the Classics Moneta Solarmetre with a versatile dual-strap system. Each timepiece is accompanied by both a classic crocodile-pattern leather strap and a sleek, interchangeable stainless-steel Milanese mesh bracelet.

Technical Specifications for Press & Retailers

  • References: FC-120W3S6 (Cloud White), FC-120LB3S6 (Glacier Blue), FC-120BRG3S6 (Bordeaux)

  • Movement: FC-120 Solar Quartz Caliber

  • Autonomy: Up to 10 months in total darkness

  • Case Details: 39 mm diameter, 8.52 mm thickness, 5 ATM / 50m water resistance

A New Benchmark in Accessible Luxury

Priced at €1,250, the Classics Moneta Solarmetre stands as a testament to the brand’s ingenuity. It is an invitation for watch enthusiasts to embrace a technologically advanced timepiece without compromising on traditional Swiss elegance.

Sparkling PR is the official PR and Communications agency for Frederique Constant in the Portuguese market.

Classics Manchette Turquoise: The Ultimate Summer Statement

By
Classics Manchette Turquoise: The Ultimate Summer Statement

Some colors define a season. This summer, turquoise takes center stage.

Radiating freshness, elegance, and a sense of escape, turquoise has become one of the most sought-after shades of the season. Evoking crystal-clear waters, sun-drenched destinations, and endless blue horizons, it effortlessly complements summer wardrobes while bringing a vibrant touch of sophistication to every look.

Frederique Constant embraces this seasonal icon with the launch of the new Classics Manchette Turquoise, a timepiece that combines Swiss watchmaking expertise with the allure of fine jewelry.

ICON OF SUMMER

At the heart of the watch lies its most distinctive feature: a dial crafted from natural turquoise stone. Long associated with protection, serenity, and positive energy, turquoise has been admired for centuries for its unique beauty and symbolism. No two stones are identical, and each dial reveals its own natural veins, textures, and reflections, making every watch a unique creation.

The latest evolution of the Frederique Constant Classics Manchette Turquoise revisits a design first introduced in 2012. Reimagined for today, the new model features seven articulated gold-tone links adorned with Frederique Constant’s signature Clou de Paris pattern. The result is a bold and contemporary silhouette that balances elegance with a subtle glam-rock spirit.

Designed to wrap fluidly around the wrist, the bracelet transforms the watch into a true jewelry piece. Its sculptural presence, combined with the vibrant intensity of the turquoise dial, creates a striking contrast that captures the energy of summer while remaining timeless in its appeal.

More than a timepiece, the Classics Manchette Turquoise is an expression of individuality. Its unique natural stone dial ensures that each piece tells its own story, reflecting the personality of the wearer and the beauty of nature itself.

For those seeking a distinctive accessory that embodies both sophistication and summer spirit, the Frederique Constant Classics Manchette Turquoise offers a refreshing interpretation of contemporary luxury.
