Pre-owned Yema Navygraf Chrono 2024, An affordable timepiece for watch and adventure enthusiasts

The Yema Navygraf Chrono, reference YNAV22CM, is a timepiece designed for enthusiasts of fine watchmaking, combining technicality and elegance with a bold character. Built to accompany its owner in a wide range of situations, it stands out for its versatility and robustness. Sold pre-owned as a full set from 2024 by Mostra, this watch comes with its original box, papers, and three interchangeable straps, allowing you to adapt its style to any occasion. It retains all its aesthetic and mechanical qualities, ensuring optimal wear for chronograph lovers and those seeking a reliable, sophisticated watch.

The Navygraf Chrono is primarily designed for demanding everyday and all-terrain use. Its 316L stainless steel case, measuring 40 mm in diameter and 13.9 mm thick, offers a bold wrist presence while maintaining comfort thanks to its balanced proportions. Its 1.80 mm thick domed sapphire crystal provides excellent scratch and shock resistance, ensuring long-term durability even in harsh environments. The blue sapphire bezel, bi-directional and fluted, offers excellent grip and clear readability with its Arabic numeral markings coated in Super-LumiNova BGW9 grade A, a technology ensuring optimal visibility in the dark.

Designed for versatile use, this watch suits both professionals and sports or outdoor enthusiasts. Its midnight blue dial, decorated with white printed indexes and a minute track, allows for intuitive time reading. The hour and minute hands, as well as the central second hand, are also coated in Super-LumiNova BGW9, providing perfect legibility in all conditions. As a high-performance chronograph, it features three sub-dials: a small seconds indicator at 9 o’clock, a 30-minute counter at 12 o’clock, and a 12-hour counter at 6 o’clock, the latter topped with the brand name. A dual day-date window positioned at 3 o’clock completes the display, offering convenient functionality.

At the heart of this timepiece is the renowned ETA Valjoux 7750 automatic movement, one of the most reliable and robust calibres available. Operating at a frequency of 28,800 vibrations per hour, it ensures high precision with a daily variation of -5 / +10 seconds. With a 48-hour power reserve, it allows the user to set it aside over a weekend without needing to wind it. This movement is widely appreciated for its ability to absorb shocks while maintaining optimal performance.

One of the Navygraf Chrono’s main strengths lies in its versatility, thanks to its brushed and polished stainless steel bracelet. It gives the watch a sportier or more formal look, secured with a double folding clasp engraved with the brand’s logo. This robust bracelet is easily interchangeable with a leather strap for a dressier, neo-vintage aesthetic, or a waterproof silicone or NATO strap, ideal for extreme conditions and aquatic activities while maintaining optimal comfort.

Designed to be worn both in urban settings and aquatic environments, the Navygraf Chrono is water-resistant to 10 ATM (100 meters), allowing for use during showers or swimming sessions. However, it is not suitable for scuba diving or the use of high-pressure water jets (see our water-resistance chart). To preserve water resistance over time, it is highly recommended not to operate the pushers or crown while the watch is submerged or wet.

With its aviation-inspired design and high-performance chronograph movement, the Yema Navygraf Chrono YNAV22CH.FR is the ideal choice for anyone seeking a stylish, durable, and versatile watch. Sold as a full set from 2024 by Mostra, this pre-owned piece is a rare opportunity for mechanical watch lovers looking to acquire a high-end timepiece in excellent condition, ready to meet the demands of everyday life.
