Casio MTP-M307D-3BV Green Dial Stainless Steel Men's Watch

The Casio MTP-M307D-3BV is a green dial moon phase men's watch with a stainless steel case and bracelet and a Japanese quartz movement. It suits men who want a dress watch with a useful complication and a distinctive face for business and everyday wear.

The Casio MTP-M307D-3BV men's watch shows the moon phase in a subdial and adds day and date windows at three o'clock. A mineral glass crystal covers the green dial, and the three-hand analog layout keeps the time easy to read. The stainless steel bracelet fastens with a fold-over clasp that has a one-touch three-fold lock. Its water resistance rating of 50 metres covers splashes, rain and hand washing, not swimming. The quartz calibre is battery powered, so the watch does not need winding.

Key features and benefits of the Casio MTP-M307D-3BV men's watch

• Green analog dial: The dial is finished in green and uses a traditional analog layout. The colour gives the watch a different look from common black or silver faces while keeping the hands easy to read.
• Moon phase display: A subdial follows the 29.5-day lunar cycle. It adds a classic watch complication you can check at a glance, and it gives the face more visual interest.
• Day indicator and date display: Two windows at three o'clock show the weekday and the date. Both are visible without opening a phone, which helps when you are checking a schedule.
• Stainless steel case and bracelet: The case and linked bracelet are stainless steel. The material resists corrosion and holds a polished finish, so the watch suits regular wear.
• Japanese quartz movement: The movement is a battery-powered Japanese quartz calibre. It drives the hands accurately and needs no winding, only a battery change every few years.
• 50 metres water resistance: The case is rated to 50 metres of static pressure. That covers rain, hand washing and accidental splashes, but it is not a swimming or diving rating.
• Mineral glass crystal: The crystal is hardened mineral glass. It stands up to everyday contact better than acrylic and helps keep the dial clear.
• Three-hand analog display: Hour, minute and second hands give the time in a standard layout. The clean face remains legible in most lighting.
• Fold-over clasp with one-touch three-fold lock: The bracelet closes with a fold-over clasp and a one-touch three-fold lock. It stays closed on the wrist and opens with a button press.
• Business, formal and everyday style: The green dial, moon phase and steel bracelet work with a suit, a blazer or smart-casual clothes. One watch can move from office hours to evening plans.

Who the men's watch is for

The Casio MTP-M307D-3BV men's watch suits men who want the look of a moon phase complication without a mechanical movement. The green dial gives the face a point of difference, while the day and date windows add practical information for workdays. A stainless steel bracelet and a water resistance rating of 50 metres make it easy to wear for commuting and office use, and the analog layout keeps it simple to read. It is aimed at wrists that suit a mid-size case and a metal bracelet.

• Boardroom meetings where a green dial adds a quiet point of difference.
• Business travel where the day and date windows help you keep track of schedules.
• Evening events where the moon phase display becomes a talking point.
• Daily commuting where the steel bracelet and 50 metres rating handle rain and knocks.

Less suitable if: you need a watch for swimming, diving or high-impact sport, because the 50 metres rating is for static pressure and does not cover dynamic water pressure.

Using and caring for the Casio MTP-M307D-3BV men's watch

The bracelet can be shortened by removing links, which is best done by a jeweller or with a link tool. Wipe the stainless steel case and bracelet with a soft cloth and mild soapy water, then dry them well. Keep the watch away from strong magnets, solvents and perfume. The 50 metres rating allows a rinse under a tap, but do not operate the crown while the watch is wet. Replace the battery at a qualified service centre so the case seal is checked at the same time.

• Have a professional adjust the bracelet length for a secure fit.
• Clean the case and bracelet with a soft cloth and mild soapy water.
• Use a microfibre cloth on the mineral glass to remove fingerprints.
• Store the watch in a dry place when it is not worn for long periods.
• Rinse with fresh water after exposure to salt water or chlorine.

How to choose the right men's watch

When you choose a men's watch, start with the bracelet material, the complication set, the water resistance and the dial colour. The Casio MTP-M307D-3BV uses a stainless steel case and bracelet, adds a moon phase plus day and date windows, and carries a water resistance rating of 50 metres for everyday splashes. Its green dial is the main style choice. If you need swim-rated water resistance, a leather strap or a larger case, this model is not the right match.

Frequently asked questions

What is the case made of?

The case is stainless steel. That material resists corrosion and keeps its polished finish with normal care.

Does the moon phase display need setting often?

The moon phase subdial follows the 29.5-day lunar cycle and only needs occasional correction. It is a display complication, so it does not change the timekeeping.

How water resistant is the Casio MTP-M307D-3BV men's watch?

It has a water resistance rating of 50 metres. That covers rain, hand washing and splashes, but the watch is not intended for swimming or diving.

What movement does the watch use?

A Japanese quartz movement powers the hands. It runs on a battery, needs no winding and keeps time with the accuracy expected from quartz.

Can I adjust the bracelet myself?

Yes, the bracelet has removable links, and you can take them out with a link tool. A jeweller can also adjust the length quickly if you prefer.

Is the mineral glass crystal scratch proof?

No, mineral glass is not scratch proof. It resists everyday scratches better than acrylic, but hard impacts can still mark it.

The box contains the Casio MTP-M307D-3BV watch, a manual and a warranty card. No extra straps or tools are supplied.

Who is the Casio MTP-M307D-3BV suited to?
