Casio MDV-107D-3A Men's Green Dial Stainless Steel Dive Watch

The Casio MDV-107D-3A is a men's dive watch with a green sunburst dial and a stainless steel case and bracelet. It suits men who want one watch for swimming, snorkeling, recreational diving and daily wear, and its 200-meter water resistance is the main reason to choose it.

This green dial stainless steel dive watch pairs a 44 mm case with a matching three-link bracelet and a fold-over clasp with safety catch. A quartz Calibre 2034 movement keeps time to within plus or minus 20 seconds per month, so there is no winding routine. Super-LumiNova on the hands and hour markers keeps the dial readable in low light, and the unidirectional rotating bezel tracks elapsed minutes. Hardened mineral glass protects the dial from everyday scrapes.

Key features and benefits of the Casio MDV-107D-3A

• 200-meter water resistance: The case is sealed to 20 bar, which covers swimming, snorkeling and recreational diving. You can rinse the watch in fresh water after a salt-water session without worrying about the seal.
• 316L stainless steel case: The 44 mm case is made from 316L-grade stainless steel, a corrosion-resistant grade used in watch cases. It holds its silver finish through daily knocks and salt-water exposure.
• 316L stainless steel bracelet: The three-link bracelet is also 316L stainless steel and closes with a fold-over clasp that has a safety catch. The clasp stays shut during active movement, and the bracelet can be adjusted with a tool.
• Green sunburst dial: The green dial has a sunburst finish that changes with the light. It gives the watch a distinct look that works with casual and business-casual clothes.
• Quartz Calibre 2034 movement: The battery-powered Calibre 2034 quartz movement is rated to within plus or minus 20 seconds per month. It keeps time without winding and needs a battery change every few years.
• Super-LumiNova hands and markers: The hour, minute and second hands and the applied hour markers carry Super-LumiNova, a luminous coating that glows in darkness. The 12 o'clock triangle helps you orient the dial quickly, so the whole face stays readable in low light.
• Unidirectional rotating bezel: The 60-click bezel turns only counter-clockwise, so it cannot be knocked past your start time. Align the pip with the minute hand to track elapsed minutes underwater.
• Hardened mineral glass: The crystal is hardened mineral glass, which resists everyday abrasions better than acrylic. It protects the dial from sand, rock contact and desk scrapes.
• Screw-down crown and solid case back: The crown screws into the case and the rear is closed with a solid case back. These two seals are part of how the watch reaches its 200-meter rating.
• 44 mm case with 22 mm lugs: The case measures 44 mm across and 13 mm thick, and the lugs take a 22 mm strap. That size fits most wrists comfortably, and a 22 mm rubber, NATO or leather strap can replace the bracelet if you want a different look.

Who the dive watch is for

The Casio MDV-107D-3A suits men who want one watch for the office and the water. Its 200-meter water resistance covers swimming, snorkeling and recreational diving, while the green dial and steel bracelet give it a smart look for casual or business-casual dress. The quartz movement removes the need to wind the watch, and the luminous dial helps in early-morning or late-night outdoor use.

• Weekend recreational divers who log bottom time on trips
• Swimmers and snorkelers who rinse gear after each session
• Commuters who want a tough, legible watch for rain and sweat
• Outdoor enthusiasts who need a timer for hikes, climbs or paddle sessions
• First-time watch buyers moving up from plastic sport watches

Less suitable if: you prefer a slim profile under a close dress-shirt cuff, because the 44 mm case and 13 mm thickness sit visibly on smaller wrists.

Using and caring for the Casio MDV-107D-3A

Rinse the Casio MDV-107D-3A in fresh water after each salt-water session and turn the bezel while rinsing to clear sand from the 60-click mechanism. Keep the screw-down crown fully closed except when setting the time. Store the watch away from strong magnets and extreme heat, and wipe the mineral glass and steel bracelet with a soft cloth to remove marks.

• Rinse and turn the bezel after ocean use to prevent salt buildup
• Check that the crown is fully screwed down before water entry
• Replace the battery every 2 to 3 years at a qualified watchmaker
• Clean the bracelet links with a soft brush and mild soapy water
• Avoid hot showers and saunas, because rapid temperature changes stress gaskets
