Product Description

Ratio 2nd Generation FreeDiver Helium Safe Quartz 1038EF102V-BLU-V02 1000M Men's Watch

The Ratio 2nd Generation FreeDiver Helium Safe Quartz 1038EF102V-BLU-V02 is for them who love to explore!

It is a watch that converts your exuberance towards unknown realms into a reality!

TheFreeDiver Helium Safe 1000Moffers you newer chances and challenges amidst newer depths and dimensions.

You never know what or where your curiosity might lead you next! So we made a watch that can take you beyond the maximum Freediving limits if needed; we made it for explorers with inquisitive minds.

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.

Specs and their implications

Water Resistance:

  • Water resistant up to 3300ft (1000m).

  • Suitable for professional and everyday use.

  • Suitable for Skin Diving, Scuba Diving, Deep diving, Swimming, Snorkeling, Surfing; spear-fishing; moderate to high-intensity land sports.


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.

Very happy with this purchase - well-made - looks great - highly recommend

I like a diving watch for everyday since I like using the bevel for timing random things - waiting in line - cooking - drive time. This is a very nice look watch - runs great - well made.

Good price

I am a scuba diver and my last Seiko I had over 30 years is no longer waterproof. Bought this with a coupon for $110. A little smaller than I expected. The bezel is not easy to turn while wearing gloves underwater.

Fox Workshop
Good quality dive watch.

This diving watch features a durable 316L stainless steel casing and a scratch-resistant sapphire crystal window. The face uses non-radioactive paint which though will need to be occasionally charged with light, is actually brighter than the radioactive versions I've seen. Powered by a reliable Japanese quartz movement, this watch delivers accuracy and convenience through its minimal need for maintenance and shock resistance. The inclusion of a helium escape valve and a uni-directional rotating bezel with a screw-down crown elevate its functionality, making it suitable for both professional and leisurely dives.
I initially experienced some discomfort with the PU strap during the first few weeks; however, as I grew accustomed to it, the watch became a comfortable extension of my daily attire. While I haven't yet submerged myself in the depths with this watch, I feel confident in its ability to perform admirably given its innovative features.
The Ratio FreeDiver 2nd generation dive watch is an enticing option for anyone seeking a high-quality and functional accessory to accompany them on their underwater adventures.

Great case, mediocre band

The watch case is really nice. The band is ok. Probably good for scuba diving if you wear it over your wetsuit but not that comfortable if you plan to wear it daily. The glow in the dark paint is good and stays illuminated for several hours if charged well under bright light. I'm going to keep the case and get another band for daily use that's more comfortable.
