Why Collectors Love This
Breguet Marine ref. 5857ST/12/5ZU is a straightforward take on the line, with dual-time functionality in a clean 42mm steel case. The silver dial and rubber strap keep the look crisp and modern, leaning into the Marine collection's sportier side. Its automatic movement adds GMT and date functions without making the dial feel busy. At 12.3mm thick, it has solid presence on the wrist without feeling bulky.
