Great looking watch
Color: Blue Gradient on Stainless Steel
This is the first Mido watch I've purchased. My first impression is it's a very nice looking watch, good quality and very attractive. The way the black to blue dial fades is very well done. The only drawback is it's almost to small for a common wrist size. I absolutely love the adjustable band and find myself using it all the time.

Total Disappointment
Color: Blue Gradient on Stainless Steel
Watch looks great but feels cheap. In addition, the advertised luminous features on the watch are non-existent.

Easily the equal of more expensive brands
Color: Black on Black Rubber
Interesting black dial and beautifully finished solid black PVD case. 39 mm perfect for my 7.25 inch wrist. Keeps time within +4 sec/day even though not COSC certified. Easily the equal of watches costing 2-4 times more like Breitling or Tag Heuer.
