When it comes to designing a high-quality watch, attention to detail is key. The specifications of a watch can greatly impact its overall performance and aesthetics. In the case of the watch we are discussing today, every aspect has been carefully thought out and crafted to create a timepiece that is both functional and visually appealing.

Design and Features


The case of this watch is made from durable stainless steel, ensuring its longevity and resistance to various environmental factors. It has a diameter of 43.5mm, which strikes the perfect balance between being noticeable on the wrist while still maintaining a sleek and stylish appearance. The thickness of the case measures 17.2mm, providing a substantial presence on the wrist. Additionally, the lug-to-lug measurement is 49.1mm, offering a comfortable fit for wearers with different wrist sizes.


The dial of this watch is a striking black color, exuding an air of sophistication and elegance. To further enhance its durability and aesthetics, the dial is made from ceramic, a material known for its scratch-resistant properties. One of the notable features of the dial is the GMT bezel, which adds an extra layer of functionality to the watch. This bezel allows the wearer to track multiple time zones simultaneously, making it particularly useful for those who frequently travel or work in international environments.


The bracelet of this watch is also crafted from stainless steel, ensuring its durability and resistance to everyday wear and tear. It features an all-satin finish, giving it a sleek and polished appearance. The three-link design adds to the overall elegance of the watch, while the pivoted end links allow for a comfortable fit on the wrist. The bracelet is an essential component of any watch, and this particular model does not disappoint in terms of both style and functionality.


The clasp of this watch is solid and machined from solid materials, ensuring its strength and reliability. It features a single swingarm twin trigger release mechanism, allowing for easy and secure fastening of the watch. The polished bevel adds a touch of refinement to the clasp, while the sizing slider allows for precise adjustment to ensure the perfect fit on the wrist. The clasp is designed with both practicality and aesthetics in mind, complementing the overall design of the watch.

Helium Escape Valve

For avid divers or individuals engaged in underwater activities, a helium escape valve is a crucial feature to look for in a watch. This particular watch is equipped with a helium escape valve, which allows for the safe release of helium gas that may have built up within the watch during deep-sea diving or saturation diving. This feature ensures the integrity and longevity of the watch, making it suitable for even the most extreme diving conditions.

Water Resistance

Water resistance is an essential feature when considering a watch for everyday wear or for water-related activities. This watch offers an impressive water resistance of 600 meters, making it suitable for recreational diving and water sports. The display case back and dual-sided crystals further enhance the water resistance of the watch, providing added protection against moisture and ensuring clear visibility of the dial in any conditions.


The bezel of this watch is designed with both functionality and aesthetics in mind. It features a ceramic insert, known for its durability and scratch resistance. The bezel is bi-directional rotating, allowing for easy adjustment and tracking of elapsed time. In addition to its general functionality, the bezel also includes GMT functionality, making it a versatile choice for frequent travelers. The timing bezel option adds an extra layer of utility, especially for those who require precise timing during various activities. The bezel is made from zirconium oxide material, ensuring its resilience and long-lasting performance.

GMT Functionality

As mentioned earlier, this watch incorporates GMT functionality into its design. GMT, or Greenwich Mean Time, allows the wearer to track multiple time zones simultaneously. This feature is particularly useful for individuals who frequently travel or work across different time zones. The GMT functionality is seamlessly integrated into the watch’s dial and bezel, making it easily accessible and intuitive to use. This additional feature adds to the overall versatility and practicality of the watch, making it a reliable timekeeping companion for the modern global citizen.

High-End Details

In addition to its functional features, this watch is distinguished by its high-end details and finishing touches. From the meticulously crafted case to the intricately designed dial, every aspect of this watch exudes a sense of luxury and attention to detail. The combination of brushed and polished surfaces on the case and bracelet adds depth and visual interest, while the discreet engravings and markings showcase the brand’s commitment to quality and craftsmanship. These high-end details elevate the watch to a new level of sophistication and make it a true statement piece for the discerning individual.


The movement of a watch is its beating heart, responsible for the accurate and precise measurement of time. This watch is powered by a high-quality movement, known for its reliability and precision. The movement ensures that the watch keeps accurate time, making it a reliable and trustworthy companion for daily wear or specific activities. The smooth and precise operation of the movement adds to the overall user experience, further enhancing the practicality and functionality of the watch.


When it comes to choosing a watch that combines functionality, durability, and aesthetics, this particular model ticks all the boxes. From its stainless steel case and ceramic dial to its GMT functionality and high-end details, every aspect of this watch has been carefully designed and crafted to create a timepiece that is both visually striking and highly functional.
