Rolex

I went through my picture and the dial of the watch gives a totally different impression on shallow draft coral reefs... That was in about 10 meters. When diving into about 20 meters, the dial is still playing tricks. And finally, when diving to the maxim...  

Kari, those are really nice photos of the green monster. I have to admit, I am really beginning to like the green sub a lot. Nice to see the sub right at home in its natural element. Best, respo

I bet Rolex has a secret test verifying this effect. Beautiful watch!

Looks like you have been enjoying your Green C to the fullest. Wear it in the best of health and in the safest of depths Best regards, Alex

as I am a big fan o' Green! Cool pics!

Nice shots u have there. I supposed that the color change on the dial due to the dismissal of certain color spectrum correlated to the increase of depth when going underwater. U picked the right watch, but still i think u must rely most on your Dive Comp,... 

their stuff. It would be very difficult to explain the Color Absorption in water but I will try, anyhow, to give some kind of idea. Our eyes see only a narrow segment of the entire electromagnetic spectrum - the wawelenth range from about 400 nanometers (...  

..but the colour loss is not so exact. But to depend on your watch dial for depth...nice romantic thought! But the real demonstrate the vaguaries of colour change....the 40m photo....green dial is now black....green bezel is...still green... The blue lume... 

thank you... Cheers

There is always some good science to learn behind these phenomena. Now how about the difference in perception of green at depth between the bezel and the dial? Does that have to do with additional absorption of wavelengths by the sapphire crystal?

for me. In certain light, even on surface, the dial turns black. but I guess this is the charm of the watch. Best, Kari

that you are really warming up to your watch.... Great.... Cheers

but still, the good old Kermit feels "easier". I will wear both, every other they the Kermit, every other day the new Frog, and in some months I will know hat I like. Best, Kari

Just guessing here, jporos, but the black of the dial vs the green of the bezel is probably attributable to the different paths light will take between the two. In the case of the bezel, light (already stripped of some of the colour spectrum due to depth)... 

Seems like a viable hypothesis to me. We now require Dr. Kol to dive sans crystal to confirm
