Frequently Asked Questions

Water Resistance Guidelines

DLC Coating Maintenance

Our cases are rated to one hundred meters. Ensure the crown is fully screwed down before exposure to water, and rinse with fresh water after marine submersion.

Our midnight-black DLC coating provides extreme scratch resistance. Clean occasionally with a microfiber cloth and warm water; avoid abrasive chemical solvents.

Automatic Movement Winding

Recommended Service Intervals

The mechanical caliber winds automatically with wrist motion. If stationary for over forty hours, manually wind forty turns via the crown to restore power reserve.

To preserve mechanical integrity and water seals, we recommend a comprehensive service by our watchmakers every five years.

Direct Concierge Access

Our dedicated horological concierge is available for technical consultations, secure shipping coordination, and private exhibition showroom bookings by appointment.
