Casio MDV-107D-1A3 Duro Men's Dive Watch Black Dial Green Bezel

The Casio MDV-107D-1A3 Duro is a men's dive watch with a black dial and a green rotating bezel. It pairs a stainless steel case and bracelet with quartz timekeeping, 200-meter water resistance and a date window, making it a practical choice for daily wear and recreational water use.

Built for swimming, snorkeling and recreational diving, the Casio MDV-107D-1A3 Duro men's dive watch is rated to 200 meters (20 bar). A scratch-resistant mineral glass crystal protects the black dial, while luminous hands and hour markers stay readable in low light. The green unidirectional bezel turns one way to track elapsed time, and the stainless steel bracelet closes with a deployment clasp. A date window at three o'clock adds a useful daily detail, and the quartz movement keeps the analog display simple to live with.

Key features and benefits of the Casio MDV-107D-1A3 Duro

• 200-meter water resistance: The case is rated to 20 bar, a pressure rating that covers swimming, snorkeling and recreational diving. That means you can keep the watch on for time in the water rather than taking it off at the pool or beach.
• Stainless steel case and bracelet: Both the case and the bracelet are made from stainless steel. The metal construction gives the watch a solid feel and suits regular wear with casual or business-casual clothes.
• Black dial: The dial is black, which creates contrast behind the hands and markers. A dark background helps the time stand out when light is low or glare is strong.
• Green unidirectional bezel: The green bezel rotates in one direction only, so it will not slip backwards if knocked. You can set it at the start of a swim or dive to keep an eye on elapsed time.
• Luminous hands and hour markers: The hands and hour markers carry luminescent material that charges in light. They then glow in dim conditions, so you can read the time at night or in dark water.
• Scratch-resistant mineral glass: A mineral glass crystal covers the dial and is treated to resist scratches. It protects the face from everyday contact with sleeves, bags and poolside surfaces.
• Quartz movement: The watch runs on a quartz movement, which is battery powered. Quartz timekeeping is known for accuracy and needs little attention beyond battery changes.
• Date window: A date window sits at three o'clock on the dial. It shows the day of the month, which is handy for daily planning and travel.
• Deployment clasp: The bracelet fastens with a deployment clasp rather than a simple pin buckle. The clasp keeps the band closed and makes the watch easier to put on and take off.
• Analog display: The analog face uses hands rather than a digital screen. That layout suits quick reads and gives the watch a traditional dive-watch look.

Using and caring for the Casio MDV-107D-1A3 Duro

Fresh water is the simplest care step for the Casio MDV-107D-1A3 Duro. After a swim in the sea or a chlorinated pool, rinse the case and bracelet under lukewarm tap water and dry them with a soft cloth. A mild soapy brush now and then lifts salt and grime from the stainless steel links. Keep the crown untouched while you are underwater, and treat the mineral glass and bezel with the same ordinary care you would give any metal watch.

• Rinse under fresh water after salt water or chlorine exposure.
• Clean the stainless steel bracelet with a soft brush and mild soap, then dry it fully.
• Avoid pressing the crown or buttons while the watch is submerged.
• Have the water resistance seals checked by a professional every one to two years.
• Replace the battery when the second hand begins to jump in two-second steps.
