6 reasons why you should go for the Ratio FreeDiver Helium-safe 1000M watch
-
A well-done watch that’s solidly constructed, theRatio FreeDiver Helium Safe 1000M Blue Dial Stainless Steel Quartzis an all-around instrument for marine enthusiasts and desk-divers alike. This one joined the hit parade immediately after the 200m Freediver made to the scene and became an instant hit.
-
This excellent tool/diver watch makes you aspire for deeper underwater realms. It has amazed everyone with its wide depth range and features. It surfaces for everyone who looks forward to newer experiences perilous yet pleasurable.
-
TheRatio FreeDiver Helium Safe 1000M Blue Dial Stainless Steel Quartz1038EF102V-BLU-V02 is a heavy watch. The heavy-gauge surgical steel construction (case, screw-down crown, engraved case-back w/image of a free diver and the deployment clasp) gives it the weight. It pleasantly assures its presence with its heft while increasing the momentum of your hand’s movements, rather than tying you down with its weight. The thick gauge, surgical-grade stainless steel and the sapphire crystal offers high resistance against tremendous water pressure; physical impacts and violent tugs. The crystal, the case and the case back protect the Japanese quartz movement (with its own shock/magnetism resistant features) within entirely against knocks, bumps and drops.
-
A large sized dial made of brass and painted using silkscreen technique; a big date window and prominent hands and hour markers offer maximum visibility under murky environments and when under pressing situations, you do not have to squint to focus on the dial to read the time (or the bezel/timer reading). A big advantage is the non-radioactive lume-filled prominent hour markers (especially at 12, 6 and 9); they are big, bright and with an almost infinite longevity. It also ensures longer hours of illumination.
-
The serrated bezel, the grooved crown and the knurled helium-valve cover – All facilitate a firm grip with wet fingers, with or without the diving gloves on. It is advised not to operate the crowns under wet conditions. Note: You’ll need the helium valve in your watch for times when you are in a chamber filled with breathing mixture; not necessarily diving bells. You open the valve to let the trapped helium out, which got past the gaskets and seals due to their very fine dimensions. A decreasing external/environmental pressure would make the helium to expand fast and damage the seals, crystal and gaskets in an attempt to escape. The helium valve provides an outlet for the built up pressure to escape.
-
The hour and minute hands of theRatio FreeDiver Helium Safe 1000M Blue Dial Stainless Steel Quartz1038EF102V-BLU-V02 are unique in their shapes. The hour and minute hands are a mix between arrow and sword shapes while the seconds-hand is an improvisation on the sword-style. The red-border on the minutes hand ensures you do not miss out on its position while using the bezel as an elapsed-time indicator.
Ratio FreeDiver Helium Safe 1000M Blue Dial Stainless Steel Quartz: A sum up of time and personal experiences
TheRatio FreeDiver Helium Safe 1000M Blue Dial Stainless Steel Quartzis a great tool watch to which anyone who takes freediving seriously should give a thought. Its specs match that of any pro-grade diver watch but the cost doesn’t. TheRatio FreeDiver Helium Safe 1000M Blue Dial Stainless Steel Quartzwears a tag that’s unbelievably lower than the rest in its league. You’ll be hard-pressed to find another watch from another brand that offers for the same amount.

Luminescence
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.

A beefy scuba diving watch – I have always wanted an authentic beefy scuba diving watch. It checked all my boxes on features a diving watch should have & all without breaking the bank. It’s basically a Seiko SKX diver watch with Seiko guts! The only chink in this watches armor was the band. It’s beefy & hard & uncomfortable. I changed mine out for a much more comfortable silicone band ordered on Amazon.
Nice watch , I like it as much or better than my Tag..
perfect-love the watch-have lots of divers- for day to day use is perfect-highly recommended. shipping super fast. don’t forget about tax and duty . is not included. Still will buy again. this is my first review purchased 3 watches.
Great watch and great value. I have had it for almost a year and it hasn’t missed a beat. It is very accurate and the luminosity is good. The only fault I have found is that the uni directional bezel is easily caught and turned
I’m very satisfied with my new cool watch (Ratio Freediver 1000 meters), for a very good price (69% off).
