The stainless steel case gives the watch a robust and substantial feel, while the black dial adds a touch of elegance. The combination of these elements creates a visually striking timepiece that is sure to turn heads. The stainless steel bracelet complements the case perfectly, adding to the overall sophistication of the watch.

One of the standout features of the Moonwatch Professional is its Lemania-based Master Chronometer caliber 3861 movement. This highly accurate and reliable movement ensures precise timekeeping and is a testament to the watch’s exceptional craftsmanship. The Hesalite crystal, known for its scratch-resistant properties, protects the dial and enhances its clarity.

In terms of its dimensions, the Moonwatch Professional features a 42mm case, which provides a perfect balance between wearability and presence on the wrist. With a thickness of 13.7mm, the watch sits comfortably on the wrist without feeling overly bulky. The 47.2mm lug-to-lug distance ensures a snug fit and enhances the overall comfort of the watch.

Lugs and Bezel

The Moonwatch Professional features design elements that enhance its overall functionality and durability. The liar-style lugs, characterized by their downward curvature, ensure a comfortable and secure fit on the wrist. The polished bevel at the tips of the lugs adds a touch of refinement and emphasizes the attention to detail that goes into the creation of this timepiece.

The anodized black tachymeter insert on the bezel is not only aesthetically pleasing but also serves a practical purpose. It allows the wearer to calculate speed based on time and distance, adding a useful feature to the watch. The diagonal orientation of the dot at 75 further enhances the readability of the bezel, making it easier for the wearer to track elapsed time.

Dial and Hands

The dial of the Moonwatch Professional is protected by a thermoplastic crystal, also known as Hesalite. This crystal, originally developed for NASA’s space programs, offers excellent clarity and minimizes reflections, ensuring optimal legibility even in bright lighting conditions. The functional and NASA-approved design of the dial pays tribute to the Moonwatch’s storied history and adds a sense of authenticity to the timepiece.

The white varnished hands on the black dial provide a high contrast that enhances legibility. This is particularly important in low-light situations, where the luminosity of the hands allows for easy timekeeping. The subtle changes in indices and registers add a touch of sophistication and demonstrate the attention to detail that Omega is known for.

Movement and Certifications

The Moonwatch Professional is powered by the caliber 3861 movement, which is based on the Lemania cam lateral clutch chronograph. This manual-winding movement offers exceptional accuracy and reliability, ensuring precise timekeeping. With a power reserve of 50 hours, the watch can go for extended periods without requiring winding, providing convenience and peace of mind to the wearer.

The free sprung balance and silicon hairspring of the movement further enhance its accuracy and resistance to external shocks. The coaxial escapement, a hallmark of Omega’s watchmaking prowess, ensures long-term stability and performance. The Master Chronometer certification guarantees the watch’s superior precision, magnetic resistance, and overall quality. Additionally, the Moonwatch Professional meets the COSC (Contrôle Officiel Suisse des Chronomètres) and METAS (Swiss Federal Institute of Metrology) standards, further affirming its reliability and precision.

Water Resistance and Durability

The Moonwatch Professional boasts a water resistance of up to 50 meters, making it suitable for everyday wear, including activities such as swimming and shallow diving. This level of water resistance ensures that the watch remains protected even in wet conditions, adding to its overall durability.

The stainless steel case and bracelet, combined with the scratch-resistant Hesalite crystal, contribute to the watch’s robustness and long-lasting performance. The meticulous attention to detail in the construction of the watch ensures that it can withstand the rigors of daily wear and remain a reliable timekeeping companion for years to come.


In conclusion, the Moonwatch Professional is a contemporary timepiece that combines timeless design with exceptional functionality. Its stainless steel case, black dial, and stainless steel bracelet create a visually appealing watch that exudes refinement and elegance. The Lemania-based Master Chronometer caliber 3861 movement ensures precise timekeeping and reliability, while the Hesalite crystal protects the dial and enhances legibility.
