After a period dominated by collaborative timepieces, Milan’s Unimatic returns to its independent roots with the Diving Heritage Collection—a comprehensive nine-watch series that channels Mediterranean warmth through vintage-inspired design.
This isn’t just another nostalgia play; it’s a carefully curated exploration of sun-faded aesthetics that transforms the brand’s familiar silhouettes into something distinctly evocative of aged seaside adventures.
The collection’s structure reveals Unimatic’s methodical approach to design expansion. Three core models—the reliable Modello Uno diver, the travel-ready Modello Uno GMT, and the sporty Modello Tre chronograph—each appear in a trinity of colorways that speak to different eras of diving history.
Matte black channels the professional tool watch tradition, while tropical brown evokes the patina of decades spent in saltwater and sunlight. The “vintage navy” option strikes a balance between military heritage and maritime elegance, creating a palette that feels both timeless and distinctly contemporary.

Heritage Meets Modern Performance
Unimatic hasn’t sacrificed functionality for aesthetics in this vintage-focused release. Each timepiece maintains the brand’s commitment to serious water resistance, with all models rated to 300 meters and individually pressure-tested to ensure reliability beneath the waves.
The brushed steel cases retain their robust construction, while screw-down crowns across the line—and screw-down pushers on the chronograph—reinforce the collection’s professional diving credentials.
The vintage aesthetic extends beyond surface-level color choices into thoughtful details that enhance the nostalgic appeal. “Old radium” colored Super-LumiNova creates an aged luminescence on indices and hands, suggesting decades of faithful service without compromising modern visibility standards.
The GMT model’s oversized, hollowed arrow hand receives matching lume treatment, while the unidirectional aluminum bezels showcase Unimatic’s refined typography in warmer, darker tones that complement the overall vintage narrative.
Accessible Luxury
Unimatic has strategically positioned this collection in its mid-tier segment, utilizing proven Seiko movements that deliver reliability without premium pricing. The Modello Uno employs the workhorse NH35A automatic movement, while the GMT variant features the NH34A “caller” GMT caliber for dual time zone functionality.
The Modello Tre chronograph utilizes the VK64A mecha-quartz movement, offering precise timing capabilities with the satisfying mechanical feel of traditional chronograph operation.
This movement selection keeps the entire collection accessible, with the Modello Uno diver and Tre chronograph priced at €625 each, while the GMT commands €750—all comfortably under the thousand-euro threshold. The limited production run of 300 pieces per model creates appropriate exclusivity without artificial scarcity, allowing enthusiasts to acquire these vintage-inspired pieces while maintaining their collectible appeal.
The Diving Heritage Collection represents Unimatic’s maturation as a brand capable of mining its own design language for fresh inspiration. By applying sun-baked aesthetics to proven case architectures and reliable movements, the Milan-based manufacturer has created a cohesive collection that honors diving watch heritage while establishing its own distinctive voice in the vintage-inspired segment.
