Buy a moonphase watch by verifying the function, movement, fit and support before the dial makes the decision for you.
1. Is it a real moonphase?
A real moonphase tracks the waxing and waning moon, while a day-night display normally makes a 24-hour rotation. Check the calibre, manufacturer documentation and setting instructions.
2. Does quartz or automatic suit your routine?
Quartz keeps running while off your wrist. Automatic offers mechanical character, but may need resetting after its power reserve runs down.
3. What crystal is over the dial?
Mineral crystal is common at accessible prices; sapphire offers stronger scratch resistance. Check whether the specification is solid sapphire, not simply a coating.
4. How will the case wear?
Compare lug-to-lug length, thickness, lug shape and wrist photos alongside diameter. The Lunar Gunmetal is listed at 40 mm, 45 mm lug-to-lug and 8.8 mm thick.
5. What does water resistance mean in real life?
ATM and metres are laboratory ratings, not a diving instruction. Follow care guidance, keep the crown closed and treat leather straps cautiously around water.
6. Are materials named precisely?
Look for 316L steel, exact crystal and coating, bracelet material, calibre and water-resistance rating. Vague claims do not make comparison easier.
7. Can it be serviced?
Ask whether the battery, bracelet, clasp and spring bars can be replaced. MIYOTA lists day, date, month and moonphase for its 6P00, with about three years of battery life and ±20 seconds per month.
8. What will you actually pay?
Compare tax, delivery, possible import charges, return costs and warranty terms—not only the price beside the buy button.
9. Is there evidence beyond the product render?
Look for wrist photos, close-ups, complete specifications, clear returns terms and purchase-linked reviews.

Compare total cost before trusting a discount.
FAQs
Can a quartz watch have a real moonphase?
Yes. Moonphase describes the display; quartz describes the power and timekeeping system.
What should I check first?
Confirm the calibre and function, then compare crystal, dimensions, water resistance, materials and support.
Is 40 mm too big for my wrist?
Not necessarily. Lug-to-lug length, thickness and case shape matter as much as diameter.
Is sapphire crystal worth it?
For daily wear, it is often valuable for scratch resistance.
How often does a quartz moonphase need a battery?
It depends on the movement. MIYOTA states around three years for the 6P00.
Conclusion
Choose the watch whose verified details match your life, then choose the dial you love.
