CASIO MTD-140-2A Men's Blue Dial 100M Water Resistant Watch

The Casio MTD-140-2A is a men's analog watch from the Marine Sports series, recognised by its blue dial and 100-meter water resistance. It combines a silver stainless steel case with a black resin band, so it suits active days and everyday wear. The watch is made for men who want one timepiece for swimming, training and casual office use.

The Casio MTD-140-2A men's watch has a silver stainless steel bezel and case around a blue face. Thick luminous hands and geometric index markers are treated to glow after light exposure, which helps when you check the time in low light. A date window at 3 o'clock shows the day of the month. The black resin band closes with a pin buckle, a simple strap fastening with a metal pin through a hole. Inside, an analog quartz movement keeps time, and the 10 bar rating supports swimming and snorkeling.

Key features and benefits of the Casio MTD-140-2A

• 100-meter water resistance (10 bar): The watch is rated for 10 bar, a measure of pressure used for water resistance. That rating covers swimming and snorkeling, but not scuba diving.
• Luminous hands and geometric index markers: These parts of the blue dial glow after exposure to light. They make the time easier to read in dim conditions, such as early morning or evening.
• Silver stainless steel case and bezel: Stainless steel is a metal that resists rust and everyday knocks. The case and bezel protect the movement and give the watch a clean silver finish.
• Black resin band: Resin is a lightweight synthetic strap material that dries quickly. The band stays comfortable during long wear and is easy to rinse after a swim.
• Pin buckle clasp: The strap fastens with a metal pin through a chosen hole. This simple closure lets you adjust the fit quickly.
• Date window at 3 o'clock: A small calendar opening shows the day of the month. You can check the date without reaching for your phone.
• Analog quartz movement: Quartz movement uses a battery and a quartz crystal to keep time. It gives reliable timekeeping with little routine attention.
• Blue dial with silver case: The blue face sits against a silver stainless steel case. The pairing gives a neat look that moves from swim gear to casual office clothes.
• Marine Sports series design: The watch belongs to Casio's Marine Sports line, which is styled for water sports and daily wear. Its shape and colours work across active and relaxed settings.
• Men's analog format: The watch is intended for men and uses a traditional analog display. Hands and markers give a quick read without menus or modes.

Who the Men's Watch is for

The Casio MTD-140-2A suits men who want a single analog watch for water sports and everyday routines. It is a practical choice for swimmers, snorkelers and outdoor enthusiasts who need 100-meter water resistance, and for professionals who prefer a tidy blue dial at work. The resin band and luminous display also help during early training or late finishes.

• Lap swimming and recreational snorkeling in a pool or open water.
• Gym sessions and outdoor runs where a secure resin strap helps.
• Office days that call for an understated analog watch.
• Weekend hikes or boat trips when low-light readability matters.
• Travel where a date window and water resistance reduce the need for extra watches.

Less suitable if: you need a dive computer with depth logging, or you want a metal bracelet for formal occasions. The Casio MTD-140-2A is rated for swimming and snorkeling, and it comes on a black resin band.
