Nivada Grenchen Chronosport Blue: Vintage Spirit, Modern Execution
Nivada Grenchen continues to expand its Chronosport collection with a striking new edition—the Chronosport Blue. This latest release builds upon the retro foundation of the original Chronosport, a series inspired by the brand’s 1970s chronograph lineage, now enhanced with modern mechanics and refreshed design cues. Limited to just 100 pieces worldwide, this exclusive edition adds rarity to an already distinctive timepiece.

A Vintage Soul with Contemporary Precision
At the heart of the Chronosport Blue beats the reliable ETA 7750 automatic chronograph movement, known for its robustness, serviceability, and decades-long presence in professional-grade timepieces. The movement operates at a frequency of 4Hz (28,800 vibrations per hour) and provides a 42-hour power reserve, ensuring consistent performance for daily use.
While the 7750 typically powers tri-compax layouts, the Chronosport Blue adopts a bi-compax configuration. It features a 30-minute counter at 12 o’clock, a running seconds sub-dial at 9 o’clock, and a date display positioned at 3 o’clock for a balanced and highly legible dial layout.
A Textured Dial with Character
The defining visual element of this model is its matte petroleum-blue dial, enriched with a granulated texture that lends depth and a tactile character under varying light. The black sub-dials offer a sharp contrast, reinforcing the tool-watch aesthetic while remaining faithful to the original Chronosport’s vintage charm.

Around the dial’s perimeter lies a printed tachymeter scale, useful for measuring speed over a fixed distance. However, due to the curvature of the double-domed sapphire crystal, the scale is more decorative than functional at a glance. The sapphire glass adds both durability and a subtle distortion that enhances the vintage feel.
Dimensions and Comfort
The stainless steel case of the Chronosport Blue measures 38 mm in diameter, 15.7 mm thick and a length of 44.30 mm. The case is crafted from brushed 316L stainless steel and topped with a bidirectional fluted bezel featuring a black aluminum insert, 60-minute countdown scale, and lume-filled pip at 12 o’clock, adding functionality for timing and visual orientation in low light.

Versatility in Wear
Water resistance is rated to 200 meters, making the Chronosport Blue not only a capable chronograph but also suitable for swimming and light diving. The model is offered on multiple strap options, including leather, rubber, and a retro-style steel bracelet. The bracelet features a folding clasp with double push-button security and a toolless micro-adjustment mechanism, allowing for up to 13 mm of extension for on-the-fly comfort.
Pricing and Availability
The Chronosport Blue is priced at € 2,395 on strap variants, while the full stainless steel bracelet version is available at € 2,625 (taxes included). With only 100 pieces produced globally, this limited edition adds collectible appeal to an already well-rounded timepiece.

Conclusion
The Nivada Grenchen Chronosport Blue represents a thoughtful evolution of a classic chronograph design. With its automatic movement, textured dial, vintage proportions, and strictly limited production, it’s a compelling choice for collectors and enthusiasts who value both heritage and exclusivity.
