The Breguet Marine is a timepiece that bridges the gap between classical haute horology and modern sport-luxury design. As part of Breguet’s esteemed Marine collection, the 5817ST blends the brand’s centuries-old watchmaking heritage with contemporary robustness and functionality.

Breguet, founded in 1775 by Abraham-Louis Breguet, is one of the oldest and most revered names in horology, credited with many pivotal innovations—the tourbillon, the Breguet overcoil, and coin-edge case fluting among them. The Marine series adapts these traditional hallmarks into a watch designed for a more active, modern lifestyle while never losing the refinement and artistry that define the brand.

The 5817ST’s blue guilloché dial is crafted with exquisite precision, featuring Breguet’s signature wave-pattern engraving that reflects light in a captivating way. The applied Roman numerals, accented by luminescent hour markers, pair beautifully with the polished blued steel Breguet hands—an unmistakable nod to the maison’s classic aesthetic. Anchoring the dial is the oversized date aperture at 6 o’clock, a defining feature that offers both elegance and practicality.

This piece is housed in a 39 mm stainless steel case with the fluted (coin-edged) caseband—a longtime Breguet signature—and is powered by a finely finished automatic movement, visible through the sapphire caseback. Water-resistant to 100 meters, the 5817ST is perfectly suited for both refined occasions and weekend adventures. The model’s screw-down crown and robust construction add a sporty edge, while the overall craftsmanship remains thoroughly high-end.

This example comes on its original blue Breguet rubber strap with deployant clasp, designed to complement the deep blue dial perfectly. Additionally, it includes an original Breguet brown leather strap, offering a more formal option. Both straps use Breguet’s high-quality construction, with curved lug fitment for integrated elegance.
