Ace Jewelers × Elka Diversity Series II: The Swiss Collaboration That Redefines Cultural Design in Watchmaking

In 2025, as Amsterdam-based Ace Jewelers marks its 50th anniversary, the retailer has unveiled one of its most thought-provoking collaborations yet - the Ace Jewelers × Elka Diversity Series II. This exclusive pair of limited-edition watches goes far beyond mere aesthetics: it’s a sophisticated dialogue between cultures, craftsmanship, and contemporary design

. Each model - one featuring Hebrew numerals, the other Eastern Arabic numerals - embodies a philosophy of inclusivity within horology that few brands dare to explore.

From Boutique Retailer to Global Collaborator: The Story Behind Ace × Elka

Ace Jewelers has long been known for its innovative spirit. Since opening in Amsterdam in the 1970s, the family-run retailer has transitioned from a classic jeweler to a modern hub for fine watches and exclusive collaborations. Its partnership with Elka Watch Co. - a reborn Swiss brand with historic roots in Amsterdam - represents a full-circle moment in European watchmaking heritage. Elka, originally founded in the late 19th century, was reintroduced in 2022 by Dutch entrepreneur and watch designer Hakim El Kadiri, a veteran of the Swiss watch industry.

The first Ace × Elka collaboration launched in 2023 as the Diversity Series, offering four dial variations that celebrated global scripts - Western Arabic, Eastern Arabic, Chinese, and Hebrew numerals. The concept resonated strongly with collectors for its blend of culture and craftsmanship.

Now, the Diversity Series II refines that idea with two meticulously designed references: MN03 (green dial with Eastern Arabic numerals) and MN04 (blue dial with Hebrew numerals).

Design Philosophy: Where Language Becomes Art

At first glance, the new Diversity Series II might appear simple, even minimalist - but beneath that restraint lies a profound concept. Time is universal, yet the way we express it varies by culture. By incorporating numerals that represent two ancient languages, these watches remind us that design can transcend language barriers. The Eastern Arabic script on the MN03 evokes the mathematical origins of timekeeping, while the Hebrew numerals on the MN04 pay tribute to historical artistry and personal heritage - inspired by a vintage Elka owned by Ace CEO Alon Ben Joseph.

The numerals are not merely decorative: they symbolize connection. In an era where globalization often erases cultural nuances, this collaboration invites dialogue about identity and craftsmanship

. It’s a celebration of diversity, framed within the precise geometry of Swiss watchmaking.

Smaller, Sharper, Smarter: A New Case for Modern Collectors

The Diversity Series II introduces a redesigned 36 mm case built on Elka’s N Series platform. The size reduction from the original 40.8 mm ensures a more wearable, gender-neutral form that suits both modern wrists and traditional tastes. Measuring 36 mm across, 41.1 mm lug-to-lug, and 10.5 mm in height, the new dimensions create a balanced wrist presence without sacrificing durability or refinement.

The case’s pebble-like curvature, polished lugs, and domed sapphire crystal add tactile sophistication. It feels smooth, organic - like a perfectly worn river stone - yet it retains strong Swiss structural precision. Despite its elegant appearance, the new model boasts 50 meters of water resistance, up from the previous 30 m, making it more practical for daily wear. Each piece is completed with a sapphire exhibition caseback showcasing the movement within.

Inside the Movement: La Joux-Perret G101 - Swiss Powerhouse of Precision

Both versions are powered by the La Joux-Perret G101, one of Switzerland’s most respected modern calibers. Operating at 28,800 vibrations per hour (4 Hz) with a 68-hour power reserve, it’s a movement celebrated for reliability and efficiency. The no-date configuration keeps the dial clean and symmetrical - an intentional design decision that reflects Elka’s purist philosophy.

La Joux-Perret, part of Citizen Group, has established itself as a go-to manufacturer for independent brands seeking high-end performance without excessive cost. Its robust architecture, fine finishing, and long service intervals make it a natural choice for a collaborative project that prioritizes longevity and practicality.

Straps, Bracelets, and Customization

In keeping with the collaborative ethos, the Diversity Series II offers flexibility in presentation. The MN03 (Eastern Arabic) features a brown leather strap, while the MN04 (Hebrew) pairs with a dark blue one. For the first time, buyers can also select a beads-of-rice stainless-steel bracelet - a vintage-inspired option that adds tactile charm and versatility. A NATO-style nylon strap option rounds out the collection for those who prefer a more casual aesthetic.

While details of the bracelet clasp and link system remain scarce, early feedback from collectors suggests it adds visual weight without compromising comfort. This modular approach - offering multiple wear styles - signals a broader trend in modern luxury: customization and individual expression.

Pricing, Value, and Availability

Both models are limited to 50 pieces each, commemorating Ace Jewelers’ 50th anniversary. Pricing remains refreshingly reasonable given the exclusivity: €2,180 EUR on leather or NATO strap, and €2,230 EUR on the steel bracelet (including VAT). For customers outside the European Union, VAT-free prices come to €1,802 and €1,843 respectively - roughly $2,100 and $2,150 USD at current rates. Remarkably, this is the same retail price as Elka’s regular-production N Series watches, signaling that the brand’s commitment to accessibility outweighs the temptation of limited-edition markups.

Comparing the Diversity Series II to Competitors

In a market crowded with collaborations, most limited editions lean heavily on branding rather than purpose. The Ace × Elka Diversity Series II stands out precisely because it’s meaningful. Where many boutique partnerships - such as TAG Heuer’s artist editions or Swatch’s bioceramic collaborations - focus on visual novelty, Ace and Elka emphasize cultural storytelling. It’s not a watch designed to flaunt; it’s one designed to start a conversation.

Comparable microbrand collaborations often sell in the same price bracket but rely on off-the-shelf designs. By contrast, Elka’s proprietary N Series case and La Joux-Perret movement elevate this series to a category of its own. It competes directly with entry-level luxury offerings from brands like Longines, Nomos, or Oris - yet carries a deeper narrative layer rarely found at this price point.

Expert Insight: The Rise of Cultural Expression in Modern Watch Design

Watch industry analysts have noted a growing appetite among collectors for timepieces that tell stories beyond mechanics. According to data from the Federation of the Swiss Watch Industry, demand for limited editions grew 24% in 2024, particularly among younger buyers seeking authenticity and meaning. “The Ace × Elka partnership hits a sweet spot,” says Dutch watch historian Jeroen Koster. “It fuses historical reference, multicultural symbolism, and mechanical excellence - all without becoming pretentious.”

Indeed, watches like the Diversity Series II reflect a wider shift in horology: a movement toward personalization and cultural acknowledgment. They’re not just tools for timekeeping; they’re emotional artifacts.
