Breguet Marine Automatic 40mm Mens Rose Gold Watch

Product Overview

The Breguet Marine Automatic 40mm Mens Rose Gold Watch 5517BR/12/9ZU is a masterful blend of Swiss horological innovation and nautical elegance, designed for the modern gentleman who values both precision and style. As part of the esteemed Breguet Marine collection, this timepiece draws inspiration from the brand’s rich maritime heritage while embodying the refined craftsmanship that defines the maison. Crafted with meticulous attention to detail, it features an 18k rose gold case that conveys warmth and luxury, making it suitable for both professional settings and sophisticated social occasions.

Powered by the in-house Breguet caliber 777A movement, this watch exemplifies mechanical excellence. The movement operates at a frequency of 28,800 vibrations per hour (4Hz), ensuring stable and accurate timekeeping. One of its most advanced features is the inverted inline lever escapement with silicon horns—a design that reduces friction and enhances durability by minimizing contact points between components. Paired with a flat balance spring made from synthetic silicon, the mechanism delivers exceptional anti-magnetism, improved elasticity, and consistent performance across varying environmental conditions. With 26 jewel bearings and a 55-hour power reserve, the watch maintains reliable operation even after periods of non-wear, offering both convenience and peace of mind.

Key Features

• Breguet Caliber 777A Movement: Developed in-house, this automatic mechanical movement represents Breguet’s commitment to innovation and precision. Its architecture supports smooth, uninterrupted timekeeping with reduced internal wear, ensuring long-term reliability.
• Inverted Inline Lever Escapement with Silicon Horns: This refined escapement design lowers energy loss and increases efficiency by optimizing the interaction between moving parts. The use of silicon horns further enhances resistance to shocks and thermal fluctuations, contributing to overall longevity.
• Silicon Balance Spring: Unlike traditional steel springs, the flat silicon balance spring offers superior resilience against magnetism and environmental changes. It maintains consistent elasticity over time, supporting accurate readings regardless of external influences.
• 26 Jewels & 55-Hour Power Reserve: The integration of 26 sapphire jewel bearings minimizes friction within the gear train, extending the lifespan of the movement. Once fully wound, the watch continues to function for approximately 55 hours, ideal for weekends or travel when winding may be less frequent.
• Marine-Inspired Design with Rose Gold Case: The 40mm case, crafted from 18k rose gold, reflects Breguet’s seafaring legacy through clean lines and subtle textural details. Its warm hue complements a wide range of outfits, from tailored suits to smart-casual ensembles, ensuring versatility without sacrificing sophistication.
