Perfect, but packaging could use some improvement.

The Casio B640D-1A features a legible positive dial display and no distracting colored text. The screen shows the month, date, and day of the week, without unnecessary clutter. It also offers an adequate backlight for viewing in low light. The stainless steel strap is unpainted, reducing the visibility of scratches and wear. The watch arrived in perfect condition, without any damages, however the circular case it was in was ajar and not fully closed. Despite that, everything was in order and there was no damage, so I have no complaints.

good watch with display features I need

I need the display features for my work - the day of the week and month-date are helpful for me as I have to work back and forth on data entry from today to yesterday on reports. The watch is helpful since I can at a glance keep the dates and days correct.
