Breguet gives the Marine 5517 an icy-blue guilloché dial

In 2026 Breguet refreshed its Marine range with an icy-blue dial inspired by the shifting light of the sea. The Marine 5517 pairs the classical house's decorative traditions with a contemporary sports-watch silhouette.

The 40mm case is made from 18-carat white gold, framing an intricately hand-guilloché dial that catches light at different angles. Applied hour markers and luminous hands make the elaborate finish practical as well as decorative.

An automatic calibre 777A provides a stated 55-hour power reserve. The watch includes a date display and offers 100 metres of water resistance, retaining the Marine collection's everyday versatility.

The edition feels unmistakably Breguet through its careful surface work, even as the colour and sporty case design give the watch a more modern mood.
