Watch charm
In this era of pursuit of individuality and taste, a suitable watch can not only help us control time, but also show our unique charm. Recently, Hamilton has launched a new Khaki Navy Series Frogman black PVD watch. The watch model is H77855330. This is a watch that combines diving functions with daily wearing comfort. It is very suitable for watch friends who like to dive.
The dial of this watch adopts a black matte grain design, and the minute, minute, second hands and time scale at 6 o’clock are all decorated with orange, which not only improves the overall aesthetics, but also enhances visibility, even in a dark environment, it does not affect reading time. Moreover, the hands and time scales of this watch are coated with white SuperLumiNova, which can also emit a faint light at night or in an underwater environment to guide the direction forward.

The most commendable thing is the crown locking device of the Hamilton diving watch. This design is inspired by the navy’s diving equipment, which can effectively prevent seawater from penetrating into the case. Even during deep-sea diving, there is no need to worry about the watch being damaged. Hamilton’s design was put into use as early as 1943, which shows its long history.
Movement performance
In the movement part of the watch, H77855330 is equipped with the H10 automatic movement independently developed by Hamilton. This movement is improved based on ETA 2824 and has higher stability and accuracy. The H10 movement has 25 jewels, a vibration frequency of 21,600 times per hour, and a power reserve of up to 80 hours. This means that even if you don’t wear the watch on the weekend, you don’t have to worry about it stopping if you leave it for three days.

As a Swiss watch brand, Hamilton’s continuous innovation in mechanical watch technology has long been a well-known fact in the industry, and the H10 movement is the best proof. Compared with ETA 2824, it has significant improvements in core components such as the balance wheel and barrel, which not only improves the performance of the movement, but also shortens assembly time and improves production efficiency.
Moreover, the balance wheel frequency of the H10 movement is 6 times per second, which is already a very good parameter among watches in the same price range, ensuring the accuracy of the watch’s travel time.

Suitable to wear
The H77855330 watch is 46 mm in diameter and 13.6 mm thick, making it ideal for wearing a diving suit. Although this watch is 300 meters waterproof, Hamilton did not cut corners because of this, but is equipped with a screw-in crown with a protective device.
In this way, even during deep sea diving, there is no need to worry about the crown loosening and causing seawater to penetrate into the case. Water resistance is the most important indicator of a diving watch, and Hamilton has obviously done enough homework in this regard.
This watch uses a black PVD-coated stainless steel bottom cover, which is not only beautiful and elegant, but also has good corrosion resistance. Neither sea water nor high temperatures will cause any harm to it.

This watch features a black rubber strap, which is extremely comfortable and ideal for long-term wear. Paired with a black PVD-coated stainless steel pin buckle, it not only improves the overall aesthetics, but also facilitates the wearer to adjust the tightness to ensure a comfortable wearing experience.
This watch sells for 1,275 Swiss francs, which is equivalent to about 11,200 yuan. For such a watch that combines diving performance with daily wearing comfort, the price is still very worthwhile.
Conclusion
This Hamilton watch is really both practical and beautiful. It can not only accompany you to dive in the sea, but also show your personality in daily life. I personally think this price is reasonable, especially for friends who like diving, the price-performance ratio is very high! What do you think? Has it been planted?
