Precision Engineering & Movement
This timepiece is equipped with a precise automatic caliber, engineered to maintain an accuracy within -3/+3 seconds per day, aligning with chronometer standards. The movement features a column wheel chronograph and flyback function, mirroring the operational smoothness of the genuine mechanism. Each watch undergoes a 72-hour power reserve verification and amplitude testing before shipment to ensure long-term reliability and performance consistency.
Superior Materials & Construction
Crafted from 904L stainless steel, the case and bezel offer enhanced corrosion resistance and a premium finish. The transparent case back and anthracite grey skeleton dial reveal the intricate movement. The case measures 45.00mm in diameter and 15.85mm in thickness, with a lug width of 24mm, ensuring a proportional and substantial wrist presence. The total weight is approximately 120g, providing a solid feel.
Strap, Clasp & Wearability
The watch is fitted with a flexible blue rubber strap, adjustable via a push-button folding clasp made from matching 904L steel. The strap is designed for comfort and durability, suitable for daily wear. User feedback indicates the clasp operates smoothly and secures reliably. The overall design ensures a comfortable fit for wrists ranging from 6.5 to 8 inches.
Testing & Quality Assurance
Every unit passes a rigorous 3 ATM (30-meter) water resistance test in a controlled pressure chamber, as documented in our quality logs. However, like many complex timepieces, it is not recommended for swimming. Our quality control includes checks for dial alignment, hand function, bezel rotation, and timing accuracy over a 7-day period.
Packaging & After-Sales Service
The watch arrives in protective packaging that includes a warranty card and user manual. It is backed by a 2-year international warranty covering movement defects. Our service network provides transparent repair timelines, typically within 4-6 weeks for movement servicing. Customers can verify service status online using their unique order number.
