Ratio NATOR04 Black 20mm Nylon Watch Strap (worth US $15.00)
Ratio Skysurfer Pilot Black Textured Dial Leather Automatic RTS310 200M Men's Watch
Ratio Skysurfer has been ranked among the best men's watches by Wrist Enthusiast.
This young, Singaporean brand might not be on your radar, but their skysurfer collection offers a refined take on the WWII-era pilot's watch. Contrary to strict, military usage, it offers more versatility and is one of the few pilot’s watches with a diving capability and is a far more affordable option. The ruggedness is in its build; not in its looks.

Designed in Italy
Each of the hour and minute hands of the Ratio Skysurfer watches comprises two parts. These are the base part and the top part placed one atop the other. The 3D visual effect comes from this design maneuver; its prominence is further enhanced by the application of the high-quality luminous paint from Japan! The thin, cylindrical seconds-hand has the Ratio logo attached to its end. This logo, apart from counter-balancing the seconds-hand, enhances the overall visual appeal of the watch face.
We have chosen a non-radioactive, nontoxic photo-luminescent paint from Japan for Ratio Skysurfer watches. When charged under bright sunlight continuously for 8 hours, it will give you an afterglow that will last through the night without the glow fading too much.
Both the Type A and Type B Ratio Skysurfer watches have the lume material applied in two formats upon the same brass base, which is the dial. Either the lume is applied to their indices and markers and the hour and minute hands or it's just the reverse - lume on the entire dial except on the hands, the indices and the markers i.e. where it previously had been.
Regardless of the layout, both offer excellent visual clarity in dark and dusk. Your choice will depend upon how much you want to stay visible at those times.
Italians are excellent designers capable of creating very intricate designs within small spaces. They are arguably the best in this aspect all over the world. That's why Ratio opted for designers from the land of Da Vinci and Michelangelo.

The 200m water resistance of the Skysurfer watches is double that of most other pilot watches. 30m to 50m or sometimes, even 100 meters is common, but you must stay prepared for the worst when out on an adventure. Ratio Skysurfer watches are one of the very few pilot watches that have 200m water resistance and doesn’t cost big bucks.
From the skies to the seas, get a Skysurfer to turn your every adventure into some serious fun and frolic!

Carved from a single block of the steel, the cases of the Ratio Skysurfer watches are brushed and polished maintaining the utmost quality. The 316L stainless steel is used for the screw-in case backs, hands, pins, and buckles alike. The low carbon content of 316L steel has high corrosion and magnetic resistance with a relatively good hardness @ 222HV (HV = Vickers Hardness).
The Skysurfer dials use three different lume layouts including a fully lumed dial in both Type A and Type B designs, the terms loosely translating to a simple, traditional clock layout and a more technical layout respectively. The dial designs are clever twists upon the Beobachtungsuhren (navigators’ watch) issued to the Luftwaffe during WWII, the entire colouring, luming and indexing done through silk-screen printing technique upon a brass base.
Brass takes colours better than any other metal and therefore, is least likely to fade over time and the silkscreen method helps us to keep the costs down without compromising on precision finishing. It also helps to us to keep up with the demands, for it is also the fastest way to apply the fine Japan lume in the most perfect way, resulting in smooth, even applications of the paint/coating materials. The slight double-domed sapphire crystal makes the dials appear bigger and the lume brighter, facilitating higher visibility whether its light, dark or twilight.
Skysurfer watches are powered by the 24-Jewels Seiko NH38A movement. The beat rate for this mechanical, automatic movement is 21,600bph (3Hz). It can run for 40+ hours on a fully wound mainspring. The seconds-hacking feature allows for accurate time-setting. Factory regulation sets it at +20 seconds but it can be further regulated to stay within +10 seconds or less. But this will break the factory seal.
