Frequently Asked Questions
How do I calibrate the multiple calendar and moon phase functions?
The OLEVS 6721 is equipped with an ergonomic multi-button side adjustment system designed for seamless time setting. The central crown controls the primary watch hands and coordinates the continuous rotation of the 24-hour moon phase indicator. The upper and lower precision push-buttons flanking the crown allow you to independently advance the date and day-of-the-week sub-dials, letting you easily synchronize the full calendar mechanism in seconds.
Are the diamond dial accents and openwork elements durable against daily impacts?
Yes, durability is built into every layer. The intricate openwork dial structure and simulated diamond markers are rigidly secured beneath a high-hardness coated glass mirror. This specialty crystal is engineered to fiercely resist daily abrasions, fine scratches, and sudden impacts, keeping the visible mechanical movement underneath completely protected while maintaining an immaculate crystalline clarity.
Does this automatic mechanical watch require batteries, and can it handle water?
No battery is ever required. This watch runs entirely on a premium automatic mechanical movement that continuously winds its mainspring by capturing the natural movement of your wrist. To safeguard its intricate multi-dial calendar array, the casing features a reliable 30M (3 ATM) everyday waterproof rating that easily handles heavy sweat, hand washing, and rain splashes. For safety, always remove the timepiece before swimming or stepping into hot showers and saunas.
