This is a good watch for the money but like other reviewers I was disappointed to see a dirty smudge mark under the crystal which is an obvious quality control issue and which should never happen. This mark is quite obvious and spoils what is an otherwise well made, accurate and easy to read timepiece. I really like the luminous function which makes the watch clear and easy to read at night. Have also bought the rose gold and brown model and have had no issues with it.
