RATIO FreeDiver Helium-Safe Dive Watch Sapphire Crystal Automatic Diver Watch 1000M Water Resistant Diving Watch for Men

The watch itself is fantastic. The built quality

bell'orologio da immersione di fattura robusta. Il movimento è preciso.

What a bargain ! great looking dive watch with helium valve . I use it in a medical hyperbaric chamber so haven't got it wet yet, but it keeps great time and is not to heavy. It appears to be well made and has a solid feel to it which I like. The luminosity is great and its easy to ready at night especially if its been in a bright place during the day. It claims to be 1000m waterproof I cant comment on that but I would be comfortable and will be recreational and tech diving with it ,

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 amazon 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

Nice white dial, decent weight, no issues so far,decent price, especially for the specs you get, very happy.

Excelente reloj, tamaño, peso, correa, mecanismo, colores, funcionalidad, estética muy muy bien, superó mis expectativas...si duda es de colección...y recomendable...
