Precision Engineering & Movement
This timepiece is powered by an automatic clone caliber based on the 324 S QA LU 24H/303, engineered to maintain an accuracy within -3/+3 seconds per day. The movement integrates the annual calendar, moonphase, and 24-hour functions, mirroring the complex mechanics of the original. It offers a stable 60-hour power reserve, verified through multiple 7-day positional timing tests conducted in our workshop, with results documented for transparency.
Material Integrity & Construction
Crafted from 904L stainless steel, the case measures 40.50mm in diameter and 11.30mm in thickness, matching the genuine specifications. The bracelet features adjustable links and a secure fold clasp, with a lug width of 21mm. Each component undergoes weight and dimension tolerance checks; the total weight is within 5 grams of the authentic reference. The sapphire crystal and gem-set indices are inspected for clarity and setting integrity.
Functional Testing & Verification
Every watch completes a standardized testing protocol. This includes a 3 ATM (30-meter) pressure test in a dry environment, with a printed test report included in the packaging. The calendar and moonphase functions are cycled through a full month to ensure correct advancement. Timegrapher data showing beat rate, amplitude, and error is captured and can be provided upon request for verification.
Quality Assurance & Packaging
Our quality control involves a 12-point inspection covering bracelet articulation, clasp operation, hand alignment, dial printing, and function activation. The package includes the watch, a warranty card, and a user manual. The 2-year international warranty covers movement defects and is facilitated through our service centers, with a documented repair timeline of 10-15 business days for standard servicing.
User Experience & Longevity
Feedback from long-term users indicates reliable daily performance in office and casual environments. The brushed and polished finishes on the case and bracelet show high resistance to minor scratches. The annual calendar requires manual adjustment only once a year at the end of February, a process clearly outlined in the included guide. Our service team has documented cases of routine maintenance, such as movement regulation and gasket replacement, performed under warranty.
