The Nivada Grenchen Chronosport Blue wristwatch is a stunning tribute to the golden era of chronographs, blending vintage aesthetics with modern Swiss engineering. Limited to just 100 pieces worldwide, this exclusive timepiece captures the essence of classic racing watches while delivering robust performance for contemporary enthusiasts. With its 38mm stainless steel case, automatic Valjoux 7750 movement, and 200m water resistance, the Chronosport Blue is built for both style and functionality. Whether you’re a seasoned collector or a newcomer to mechanical watches, this limited-edition release is a compelling addition to any collection.
The 38mm stainless steel case of the Chronosport Blue pays homage to classic chronographs of the past while ensuring a comfortable, modern fit. Its polished and brushed surfaces offer a visually appealing contrast, and its fluted unidirectional rotating bezel adds both aesthetic charm and practical usability.
Unlike many modern oversized chronographs, this 38mm case size ensures the watch remains wearable for a wide range of wrist sizes. The 12.6mm thickness also contributes to its comfortable profile, making it an excellent everyday chronograph.
The blue dial of the Chronosport 77003A45 is a striking feature that immediately captures attention. It has a matte finish, enhancing contrast and legibility. Two taupe-colored embossed sub-dials sit at the 12 and 9 o’clock positions, evoking the classic aesthetics of 1970s racing chronographs.
The white printed markers and luminescent hands ensure readability in low-light conditions, while the date window at 3 o’clock provides practical functionality. This combination of vintage-inspired design and modern enhancements makes the Chronosport Blue a versatile timepiece that works equally well in casual and formal settings.
The aluminum bezel with a 60-minute scale offers added utility for timing events. Unlike ceramic bezels that have a glossy modern look, aluminum provides a vintage feel that aligns with the retro aesthetic of the watch.
Covering the dial is a double-domed sapphire crystal with an anti-reflective coating, ensuring scratch resistance and optimal clarity in various lighting conditions. This makes the watch both durable and legible, a crucial aspect for any tool watch.
At the heart of the Chronosport Blue is the Valjoux 7750 automatic movement, one of the most respected and widely used chronograph movements in the industry.
• Movement Type: Automatic
• Jewels: 25
• Power Reserve: 42 hours
• Frequency: 28,800 vibrations per hour (4 Hz)
• Functions: Hours, minutes, small seconds, chronograph, date
The Valjoux 7750 is known for its durability, precision, and ease of servicing, making it a reliable choice for a collector’s timepiece. The 42-hour power reserve ensures it can last through an entire weekend without winding, while its robust build allows it to withstand daily wear and occasional shocks.
One of the defining features of this movement is its cam-operated chronograph mechanism, which provides a satisfying tactile feel when engaging the pushers. This makes timing events not just practical but enjoyable for watch enthusiasts who appreciate mechanical engineering.
With a water resistance rating of 200 meters (20 ATM), the Nivada Grenchen Chronosport Blue is more than just a stylish chronograph—it’s a fully capable sports watch.
• Screw-down crown and pushers: Prevents water from entering the movement
• Gasket-sealed case back: Ensures pressure resistance
• Sapphire crystal: Enhances durability against pressure changes
This level of water resistance means the Chronosport Blue can handle swimming, snorkeling, and even recreational diving, making it more versatile than most chronographs in its category.
Nivada Grenchen offers the Chronosport Blue with three distinct strap options, allowing collectors to tailor the watch to their personal style and comfort preferences:
