Product Overview

As part of Tudor’s iconic Black Bay collection—inspired by the legacy of the original 1958 dive watch—this chronograph model elevates the brand’s signature style with advanced features suited for both land and sea. The watch boasts a robust silver-tone stainless steel case paired with a rugged yet refined black canvas strap, delivering a look that transitions seamlessly from casual outings to professional settings. With a 41 mm diameter and 15 mm thickness, it sits comfortably on the wrist without overwhelming smaller frames, while its 200-meter water resistance ensures reliable performance during swimming, snorkeling, or light scuba diving. Whether you’re navigating city streets or exploring underwater terrain, this timepiece combines Tudor’s Swiss engineering excellence with everyday practicality.

Key Features

• Automatic Movement: Powered by a self-winding mechanical movement, this watch maintains accurate timekeeping through natural arm motion, eliminating the need for battery replacement. The automatic mechanism continuously winds the mainspring as long as the wearer is active, ensuring consistent performance even after short periods of non-use.
• Chronograph Functionality: Integrated stopwatch capabilities allow precise measurement of elapsed time via clearly marked sub-dials at 6, 9, and 12 o’clock positions. This feature supports activities like tracking intervals, timing workouts, or aiding in navigation—making it a versatile tool beyond basic time display.
• Black Dial Design: The matte-finish black dial offers exceptional legibility under low-light conditions, enhanced by luminescent hour markers and hands. Its clean layout emphasizes readability while maintaining a bold, understated presence that complements any attire.
• Silver-Tone Stainless Steel Case: Constructed from high-grade stainless steel, the case resists corrosion, scratches, and daily wear, preserving its polished appearance over time. The brushed finish adds subtle texture without compromising elegance.
• Canvas Strap with Tang Clasp: The black canvas band provides breathability and comfort during extended wear, reducing skin irritation compared to traditional metal bracelets. Secured by a secure tang buckle—a classic clasp type that lies flat against the wrist—it ensures a snug, adjustable fit without excess bulk.
• Fixed Bezel: Unlike rotating bezels used in dive watches for measuring dive duration, this fixed bezel maintains a streamlined profile while reinforcing structural integrity. It contributes to the watch’s minimalist aesthetic and reduces potential points of failure.
• Water Resistance (200m / 660ft): Certified to withstand depths up to 200 meters, this rating meets standards for recreational scuba diving and prolonged immersion in freshwater or saltwater environments, making it suitable for aquatic adventures.

Benefits & Use Cases

The Tudor Black Bay Chrono excels across diverse lifestyles and environments. Its automatic movement requires no external power source, relying solely on wrist motion to keep accurate time—ideal for travelers who frequently cross time zones or individuals seeking low-maintenance luxury. The 200-meter water resistance makes it a trusted companion for swimmers, surfers, and occasional divers, while the durable canvas strap remains comfortable even in humid or wet conditions, resisting odor and mildew better than leather alternatives. The 41 mm case strikes a balanced proportion suitable for most male wrists, offering visibility without excessive heft. The chronograph function adds utility beyond timekeeping: whether timing sprints during training sessions, logging travel durations, or coordinating team events, the subdials provide intuitive control. Stylistically, the matte black dial pairs effortlessly with dark denim, tailored trousers, or smart-casual ensembles, reflecting Tudor’s heritage-inspired approach that honors vintage dive watches while incorporating contemporary refinements. Collectors will appreciate the model’s place within Tudor’s lineage, and daily wearers benefit from its resilience and understated sophistication.

Important Notes

Please note that the listed item weight of 1.5 pounds includes all packaging materials such as boxes, manuals, and shipping inserts; the actual weight of the watch alone is significantly lighter. For complete warranty details—including coverage terms, claim procedures, and service center locations—customers should visit the official Tudor warranty page linked in the product information. As with any mechanical timepiece, periodic maintenance every 3–5 years is recommended to ensure optimal performance and longevity. This listing includes only the watch itself; additional accessories like extra straps or certificates are not guaranteed unless explicitly stated. To preserve accuracy and internal components, avoid exposing the watch to strong magnetic fields (e.g., speakers, motors) or extreme temperature fluctuations. Always rinse the strap after saltwater exposure and store the watch in a dry environment when not in use.
