Product Overview

The MIDO Ocean Star Decompression is a Swiss automatic watch crafted for men who value precision, durability, and refined design in equal measure. Born from over a century of Swiss watchmaking tradition, this timepiece reflects MIDO’s enduring commitment to combining technical excellence with accessible luxury. Founded in 1918 by Georges Schaeren in Le Locle—a historic hub of horological innovation in the Swiss Jura—MIDO has built its reputation on innovation, functionality, and timeless aesthetics. The name itself, derived from the Spanish “yo mido” meaning “I measure,” underscores the brand’s deep-rooted dedication to accurate timekeeping.

As part of the Swatch Group, MIDO leverages cutting-edge technology and superior materials to deliver high-end mechanical performance without compromise. The Ocean Star Decompression embodies this philosophy, integrating advanced automatic movement, robust construction, and dive-ready functionality into a single, cohesive design. Whether you’re exploring underwater environments or navigating the demands of daily life, this watch offers the reliability and elegance that serious watch enthusiasts expect from Swiss craftsmanship.

Key Features

• Swiss Automatic Movement: At the heart of this watch lies a high-performance Swiss automatic caliber. This self-winding mechanism harnesses the natural motion of the wearer’s wrist to power the watch, eliminating the need for a battery. The movement is engineered for consistent accuracy and long-term reliability, reflecting MIDO’s expertise in mechanical watchmaking.
• 80-Hour Power Reserve: Once fully wound, the watch can operate continuously for up to 80 hours—more than three full days. This extended reserve makes it ideal for wearers who may not use the watch every day, ensuring it remains accurate and ready without frequent resetting.
• 40.5mm Stainless Steel Case: The case size is thoughtfully balanced to offer a bold, masculine presence while remaining comfortable on a variety of wrist sizes. At 40.5mm in diameter and 13.4mm thick, it fits seamlessly under a dress cuff yet maintains a confident stance on the wrist, making it suitable for both professional and casual settings.
• 660ft (200m) Water Resistance: Engineered for serious aquatic use, this watch is suitable for recreational scuba diving, snorkeling, and other surface water sports. The high water resistance rating is a testament to its robust sealing and pressure-resistant construction, ensuring dependable performance in challenging environments.
• Screw-Down Crown: This essential feature enhances water resistance by securely sealing the crown against the case. It prevents water ingress during submersion and contributes to the watch’s overall durability in wet conditions, a critical safeguard for divers and water sports enthusiasts.
• Unidirectional Rotating Bezel: Designed specifically for diving, the bezel allows users to track elapsed time underwater. Its unidirectional rotation prevents accidental backward movement, which could lead to overestimating remaining dive time—adding a vital layer of safety for underwater exploration.
• Date Calendar Function: Located at the 3 o’clock position, the date display offers everyday convenience without disrupting the dial’s clean, legible layout. It’s a practical feature for professionals and active individuals alike.
• COSC Chronometer Certification: This model is officially certified by the Contrôle Officiel Suisse des Chronomètres (COSC), meaning it has passed rigorous testing for precision and reliability. Only the top 3% of Swiss watches meet this standard, affirming the Ocean Star Decompression’s exceptional accuracy.

Important Notes

While the watch is rated for water resistance up to 660ft, it should not be used in high-velocity water sports, hot water environments such as saunas or hot tubs, or during activities involving rapid temperature changes.
