Ratio FreeDiver Black Dial Sapphire Crystal Stainless Steel Automatic RTB200 200M Men's Watch

• A well-done watch that’s solidly constructed, the Ratio FreeDiver Black Dial Sapphire Crystal Stainless Steel Automatic RTB200 200M Men's Watchis an all-around instrument for marine enthusiasts and desk-divers alike. It’s among the first Freediver series that made to the scene. They became instant hits and soon went past its teens and young adults demographic and extended to the matured adults, some into hard-hitting jobs.

• This is an excellent tool watch for urban surroundings involving outdoors. It is for the everyday use of the lab assistant as much as for the snorkelling instructor at the bay side. A pleasure to wear when you want to stick to utility without acquiring things that you’ll never need.

• The Ratio FreeDiver Black Dial Sapphire Crystal Stainless Steel Automatic RTB200 200M Men's Watch is all about heavy-gauge surgical steel that doesn’t turn the watch heavy yet turns it heavy duty. Its 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 damaging water pressure (equivalent to pressure exerted by a 200m high water column on the watch’s surface area), physical impacts (including violent tugs) and magnetic resistance to handle magnetic fields from electronic and electrical equipment we come across in daily life.

The crystal, the case and the Freediver-etched case back together protect the Japanese mechanical movement (with its own shock/antimagnetic features) together against violent 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 Japan 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 and the grooved crown facilitate a firm grip with wet fingers, with or without gloves on. It is advised not to operate the crowns under wet conditions.

• The hour and minute hands of the Ratio FreeDiver Black Dial Sapphire Crystal Stainless Steel Automatic RTB200 200M Men's Watch are unique in their shapes. The hour and minute hands are a mix between arrow and syringe shapes while the seconds-hand is an improvisation on the sword-style with a circle at the tail-end. All the hands are sumptuously filled with Japan-made lume the hour markers alike. The lume dot on the bezel ensures you do not miss out on the correct time-reading.

Luminescence

Ratio uses Japanese luminescent paint for the luminescence in the Freediver 200m 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.
