Swiss Quality from a good brand
Color: Grey
This is my 4th Tissot watch. I only have a few quibbles. The band adjusts by removing wide or narrow pieces, not by adjusting with pins with a range of holes. I prefer that way to adjust a metal band. The color blue of the dial is darker in real life than the picture. I also wish the day indicator was a little larger (or my eyes were younger).

A LOT of watch for the money
Color: Grey
I purchased this piece with low expectations but was pleasantly surprised by the quality and overall esthetics. If you are a young man looking for your first watch that doesn’t break the bank, this is the one.

Not giving accurate time.
Color: Grey
Watch looks so fancy and standard but regretted to say that the pins on the bands are coming out easily, and does not giving accurate time. doesn’t worth it. Wish i can return it if possible.
