Longines debuts the Ultra-Chron Carbon, a lightweight, high-frequency dive watch, to start 2025.

The Ultra-Chron Carbon features Logines’ 43 mm diameter cushion-shaped case, crafted in an all-new lightweight forged carbon-epoxy resin case.

A sapphire crystal protects the dial side. The screw-down crown and engraved solid screw-in caseback are made of titanium. The dive watch is depth rated to 300 meters.

Thick baton-shaped hour and minutes, a long thin baton-shaped central seconds hand, and faceted indices — coated with a gray PVD treatment — display the time only against a matte (sandblasted) anthracite dial.

A generous amount of lume on the hands, indices, bezel, and chapter ring, ensure excellent visibility in low-light situations.

Completing the ultra-sporty look is a black textile strap. Retail is $4,900.
