A vastly different watch from the expensive dive computers, it is for free divers, recreational water-sports enthusiasts and professionals alike. It is nothing more (or less) than a good timekeeping device, with a timer to set your dive span. The unidirectional rotating bezel does that. You need this if you want to go further. Also makes for a stylish street-wear.

Ratio FreeDiver Helium-Safe 1000M Sapphire Automatic 1068HA90-34VA-RED Men's Watch

Meet the Ratio Ratio FreeDiver Helium-Safe 1000M Sapphire Automatic 1068HA90-34VA-RED Men's Watch!

The Ratio FreeDiver Helium-Safe 1000M Sapphire Automatic 1068HA90-34VA-RED Men's Watch is not just a timepiece, but a symbol of your adventurous spirit. This watch is more than just an accessory, it's a companion that's always ready to take on the harshest realities and toughest challenges. With its sleek design, solid construction, and unmatched performance, the Ratio FreeDiver Helium-Safe 1000M Sapphire Automatic 1068HA90-34VA-RED Men's Watch is the perfect tool for the modern-day adventurer.

A Dive watch that goes beyond the mere design!

Crafted from surgical-grade stainless steel, this watch is designed to handle the toughest conditions. With a water-resistance of up to 1000m, it's perfect for skin diving, scuba diving, deep diving, swimming, snorkelling, surfing, spear-fishing, and moderate to high-intensity land sports. The Seiko Caliber NH36 movement ensures reliability and accuracy, while the bi-directional winding system and 41-hour power reserve make it a practical and convenient choice.

Perfectly balanced!

It's not just only about performance, rather this watch is a work of art. The red dial with uniquely shaped hands and hour indices, covered by a thick A/R coated sapphire crystal, offers a perfect view above or under the water. The luminescent paint on the hands and indices ensures easy visibility in the dark, making it perfect for night dives or late-night adventures. The two screw-down crowns are placed in a manner that minimizes damage to the watch in case of a frontal impact and eliminates the chances of wrist bites if your palm folds against your wrist. Moreover, the helium escape valve allows any helium molecules that may have entered the watch to escape during deep sea diving and keeps the watch safe.

Crafted for Freediving! Prepared for beyond!

Ratio Freediver’s extreme capabilities, sum up of time and personal experiences, and its unbelievably low-cost tag make it a must-have for anyone who takes freediving seriously. Don't miss out on this opportunity to own a watch that goes beyond the mere design and is prepared for something more!

Ratio uses non-radioactive luminescent paint for the luminescence in the Freediver 1000m watch. It is a non-radioactive, radiant paint that's applied generously on the hands and the indices of the Freediver. The paint exhibits greater intensity and longer-lasting luminescence. Its output duration doesn’t let you compromise on visibility; let it even be for a few extra hours in the dark! A 10-minutes long exposure to 500 lux or higher intensity light will charge the lume for the next 3-5 hours.

A continuous 8-hour exposure to Sunlight on a normal summer day will let it glow for 10+ hours. The longevity of the paint is semi-permanent, ensuring full functionality of the watch even after years of active use.

Remarkable watch

I found it impossible to not fall in love with this watch.
This watch delivers beauty, functionality, precision, robustness and lumes galore.
Granted, I could have waited months or years to leave a proper review, but given that the watch may not even be available years from now, I can only update this review at a later date if something changes.

This watch either gains 0 seconds, or 0.5 seconds in the few days I have worn it constantly, including showers, dish-washing, sleeping, but alas, not diving yet. The precision blows my mind. I do have a 20 years old Eco-drive that basically keeps atomic time (no radio) and to get this kind of precision on an automatic is either luck or the stuff of legends.

As others have stated before me, this watch is a tank. It even looks like a melted tank. Everything is so precise and gorgeous, including the bezel action. Simply delicious sound as you rotate it and it comes to a fully centered state.

The lume, as imaged, I took from inside a closed closet and adjusted the camera to image as close to what my eye sees. The lume lasts through the whole night, all the way to the morning hours and is easily readable even then. I don't do anything special to charge it. The image was taken after 5 seconds exposing to direct sunlight, but even in office light, and then going to bed, it just shines, almost like it is an LED. Simply remarkable.

There is no question that the watch can easily be upgraded to be even more gorgeous but clearly that would increase the cost without increasing functionality, and this watch is incredibly functional.

Now, the silicon straps that it came it, I replaced with the nylon straps, but those too are far too short. If you have large wrists, like I do, I barely get to the very first hole without cutting the blood circulation and that is annoying and has nothing to do with the watch itself. It is also nearly impossible to get XL canvas or nylon straps (non Nato) from Amazon. Many brands say they have XL versions, but no option to select during ordering.

So I wonder if this watch could survive for however long on the surface of Venus, with surface atmospheric pressure of about 92 bars and 600 degree Fahrenheit temps. Both the melting point of sapphire and steel are much higher, so who knows :)

Un reloj imponente

Un reloj muy bien construido, la correa un poco corta pero en general muy bonito. Si tuviera los marcadores horarios aplicados y no pintados sería mas elegante. ¿La válvula de helio es funcional? o solo estética?


This is my first RATIO watch. I loved the dial color. The accuracy +15 spd and the beat errors is 0.5 and she has a strong amplitude.I will regulate the watch but I need more time for let the movement run couple weeks. The strap is comfortable and I think soft silicone. Inside u can see a double gasket for a deep diving. To check the watch has healthy movement I need it to open and to put on the timegrapher. I'm satisfied about everything on the lume is bad. I do recommend this model and I'm waiting for a white dial version to available for purchase.
