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.
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!
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.
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.
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.
