Yelang V5.1 Professional Mens Diving 300m Waterproof Green Luminous Automatic Mechanical Wrist watch With ETA 2836 Movement,T100 Tritium Tubes,Dual Calender,Exhaust Helium Device

I loved the blue face Yelang V5.1 with blue tritium so much that I got this one too. Side by side comparison, the green tritium glows more than the blue. That's not to say that the blue is weak, because it isn't, it is very good and looks great, but the green tritium has an even stronger glow in case you are looking for the maximum brightness. I love these Yelang watches. They are substantial, very classy looking watches for 10% the price of a Breitling or Rolex and in my opinion look as good as a Breitling or Rolex in the day and even better at night, because you can actually see them and night, and read the time in pitch black darkness all night with zero ambient light and without pushing a button for a light. These are so bright that in pitch black darkness you can actually see objects about 2 feet away using the watch.

the tritium is brighter than my seiko sun019 after it settles from initial charge but by no means even close to the freshly charged Seiko which only lasts for 2-3 minutes. i was hoping it was close to that searing bright glow of the Seiko during the super bright phase but i guess that was wishful thinking. the watch is quite thick and sturdy. the bezel feels clicky and is a bit tough to turn. have to get a good grip on it and turn it just right. feels very well built. wish there was a way to tell how much of a charge is in the watchthe crystal has a magnifying effect on it. not so prominent in the pictures but very present when looking at it.
