Product Information

Full details

The Oris Aquis Date Calibre 400 is designed for professional divers and watch enthusiasts who demand both aesthetic sophistication and high-performance engineering. Its key benefit is the reliable in-house Calibre 400 movement, which offers an impressive five-day power reserve and advanced anti-magnetic properties for modern daily wear. One caveat to consider is its 43mm case size, which may feel substantial on smaller wrists, requiring a trial fit before purchase to ensure comfort.

FAQs

What is the power reserve of this watch?

The Oris Calibre 400 features an impressive 120-hour, or five-day, power reserve.

Can I wear this watch while diving?

Yes, it is rated for 300 meters of water resistance and features a functional uni-directional rotating bezel.

Is the dial green or another color?

This model features a distinct gradient green dial.

How do I maintain the water resistance?

Always ensure the crown is screwed down completely before any water exposure and have the seals checked by a technician every few years.

What is the bezel made of?

The bezel insert is made from high-performance ceramic, which is highly resistant to scratches.

Is this watch magnetic resistant?

Yes, the Calibre 400 is engineered with advanced anti-magnetic properties.

Troubleshooting

Watch stopped despite regular wear

Ensure the crown is fully pushed in and verify if the power reserve has been fully depleted by manually winding the movement.

Bezel is difficult to rotate

Rinse the bezel under warm fresh water to remove dried salt or debris, then rotate it gently to clear any sediment.

Date is not changing at midnight

The watch is likely set to 12 hours offset; advance the time by 12 hours so the date change aligns with midnight.

Setup, Compatibility & Care

To set the time and date, unscrew the crown until it pops into the first position for date adjustment and the second position for hacking the seconds and setting the time. Always ensure the crown is fully screwed down before entering water to maintain the 300-meter seal. For care, rinse the watch with fresh water after exposure to saltwater to prevent salt build-up on the bezel and links. Use a soft, lint-free cloth to clean the case and crystal. While the movement is robust, have the watch pressure-tested by a professional authorized service center every two years if you regularly engage in professional diving activities.
