This watch has met or exceeded almost all my expectations for quality, reliability and features. The digital and analog clocks are separately set, supporting three time zones (ex. analog, digital and digital 'DL'), and all keep accurate time. There is a twenty beep alarm and two beep hourly notices. The hourly alarms are synchronized to the first digital setting. The bidirectional bezel is clicks along smoothly and generally stays put. Occasionally I'll ding it against a wall or table and afterward notice it is a click or two off 12. I cannot comment on the original band's durability, however Armor-All or other protection is suggested to extend the original band's life. I immediately replaced the factory band with a nylon 22mm Zulu NATO.

The face markers and hands are illuminated and large. but last only briefly. If you need a watch for night or low-light activities select an tritium or electroluminescent (Timex Indiglo or Casio Illuminator) watch or carry a light source for quick lume recharges.

Casio's AMW320 series offers multiple case and face styles at very affordable prices. Later, I purchased a Casio AMW320B-1A and a MDV-106D-1A1VDF. The AMW320B-1A is completely blacked out with even less night visibility, but all the same great ana-digi features. Unless you have to have that all-black look, avoid it.  In contrast, I highly recommend the MDV-106D.  This analog-only model has incredible illumination (+8 hours and strong) and a metal band. For the money, you can afford to purchase more than one Casio.

UPDATE: After purchasing a SEIKO ProspEx model, the Casio watches are all in a drawer. My brother likes them, so I gifted a few to him.
