Impressive, zero-distortion domed sapphire with a slightly bluish tinge. It is stronger than flat crystals of the same thickness and disperses impacts more efficiently. It is less likely to shatter and/or crack than a flat crystal. It is also more scratch-proof than other types of crystals
The hour and minute hands of the RTA100 are unique in their shapes. The hour and minute hands are a mix between arrow, syringe and sword shapes while the seconds-hand is an improvisation on the sword-style with a lume-filled 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.

Of course it being a diver watch it's going to be heavy. I purchased it for the large illuminated numerals . they are Brite! The day/date doesn't hurt with given my bad memory. Fit an finish are very good. The only downside is the watchband. It is heavy and somewhat clunky, tends to pinch hair and adds to weight of watch. Solved the by replacing band with rice bead band, no more pinched hair.

You can pay more for an SKX clone, but doubt it will be better. I returned an Invicta Pro Diver that felt like a billiard ball strapped to my narrow bony wrist, and after a lot of research went with Ratio. I couldn't be more pleased with my decision, and I challenge anyone to find a better value in a 200m diver with offset crown, good lume, convex crystal, day/date, quality movement, and push-button scissor band.

I was so surprised how well made this watch is. Case polishing isn't Grand Seiko but hey it was $150 USD. Lovely watch!!

Liked it but as soon as I wound it and set the time and tried to screw the crown back in...it would not screw down. I've owned dive watches since the 80s and never had a problem. So I used Amazon's return and got a refund...after a few weeks.I liked the way it looked and considered getting it replaced instead of refunded, but just didn't feel good about the quality since I've never seen a watch do this before.

Extremely well built. Seems like it should hold up under pressure. I Strongly recommend this watch brand, πRATIO. I have a couple more of them and they are great in feel, looks and style. When you put it on you know it's there but it doesn't feel overly chunky on the wrist.Thank you,SgtWall USMC 1981-1992

La calidad del reloj supera al mismo Seiko SKX, la caja y la pulsera súper sólidas, el lume es un espectáculo y dura toda la noche con buena luminosidad.

Lume was brightly lighted for 2-3 minutes was initially and then settled for next 5-6 hours. Wish it came with watch link remover like watchdive watches. Was tought using household items to remove it and save $5-10 at jeweler. Watch keeping time +10 to +20 sec a day. Steel bracelet need filling down to avoid cut from sharp edges
