Comfort is a 10! Appearance is very very nice!! Readability is excellent! Accuracy is 💯 !! Quality is a 10! Value - couldn’t love it more!! At first I didn’t think that he sent me a watch without a battery, but lo and behold I opened the box again and definitely saw the watch was working! I’ve been scammed several times- but this is truly AWESOME !!! Thank you all!!!

Hard to set day/date.

Color: A-Black

Watch very professional looking and appears to be well made. Everything about this watch is what I have been looking for at a reasonable price. The only issue I have is how to set the watches features, time, date, and day. The instructions are very clear and well written, to a point. That point being the instructions say to move the "crystal" to the first notch, to adjust the day/date, and the second notch for to set the time. What the instructions fail to mention is the day/date adjustment must be turned a full 24 hours to the next day or date settlings. Also, trying to hit just the second notch is almost impossible as the is no distinct way of knowing if you are in it or not,

Big face, easy to read.

Color: A-Green Luminous

Great watch ! Large face and hands makes it easy to read, Backface glows in dark if enough light is exposed to it. Showered a few times, no problem. Will hit the waves later this week. Update on that later. Very happy with purchase and seller. Can recommend.
