Review: Robust yet practical - Pretty sturdy watch. Easy to use and practical.
Review: A lovely Saffron Sunburst Dial - Just got my Free Diver Ratio 1000 m Helium Safe Automatic, the screw down crown is amazing and for a minute I was wondering how to get the watch initiated. Its a safe guard system and once released you can adjust the date day and time and hacking helps catch the seconds. Today the 18th Sept '25 my Ratio 'PI' watch arrived from desertcart aand it is the first day of time keeping with it, so let's see how the watch movement delivers . The lumen is the best among all my watches, almost blue fluorescence and the dial is rather more Saffron in color and a beautiful Sunburst dial. Ratio does not have a service centre but it should be able to be serviced by local professional watch keepers! Will update this review after a good use of the watch
