My FreeDiver Helium Safe 1000M Sapphire Quartz 1038EF102V arrived last week. It fulfills everything that it promises and, although I do not do saturation diving, I can say it worked very well at 17 meters of depth. It is very accurate, lightweight and very comfortable to use. As for the appearance of this Ratio, an observer can tell it is a - good quality - tool from many meters away. I say that getting a Seiko workhorse movement, saphire glass and a Helium safe valve for so little money it's a steal. My only criticism is the quality of the lume on hands, markers and pip that do not store light for a long time, but it is nitpicking because one cannot ask for every little thing for this low price. Creation Watch's service was excellent. I'm so glad I bought from them. Keep up the good work, and we will do business again.
