At Grand Caliber, every watch undergoes a meticulous authentication process to guarantee its originality, quality, and condition before reaching our customers. Our team of expert watchmakers and horologists carefully inspects each timepiece, verifying critical details such as the movement, case, dial, serial numbers, and hallmarks. Using specialized tools, we confirm the authenticity of materials and ensure that components, including bezels, crowns, and bracelets, are original and unaltered. If any part of the watch has been serviced or replaced, our experts assess whether the work was completed using genuine manufacturer parts. This thorough evaluation ensures that every watch meets our strict standards for authenticity and performance.

Beyond physical inspections, we cross-check serial numbers and reference details with manufacturer databases and industry records to confirm each watch’s legitimacy. Every timepiece sold by Grand Caliber comes with our authentication guarantee, giving customers confidence in their investment. To ensure peak performance, our watches are tested for accuracy and overall functionality. Trust is at the core of every luxury watch purchase, and we take authentication seriously. Whether you're adding a Rolex, Omega, or Patek Philippe to your collection, you can be certain that your timepiece is 100% authentic and has been expertly vetted by industry professionals.

At Grand Caliber, we strive to provide a seamless shopping experience with secure, fast shipping. All watches are in stock and typically ship within one business day after payment verification. We offer free domestic shipping via FedEx Overnight, fully insured at no extra cost. Orders are shipped to the nearest FedEx shipping center for secure pickup. Orders paid by credit card will be shipped only after the transaction is approved and settled, typically by 8:00 pm CT. Orders placed before 12:00 pm CT will ship the next business day, while those placed after 12:00 pm CT will ship on the second business day. To protect our customers, all orders must be shipped to the billing address on file with the credit card company unless an alternate shipping address is verified in advance. Orders paid via wire transfer will ship the same day funds are confirmed, with a cutoff time of 1:00 pm CT. We only accept wire transfers—no ACH or other electronic transfers.

Grand Caliber exclusively ships through FedEx and does not accommodate alternative shipping methods. FedEx Overnight shipping applies to all U.S. orders and delivers Monday through Friday; no weekend or holiday deliveries are available. A valid street address is required, as FedEx does not ship to P.O. boxes, APO/FPO addresses, or U.S. Territories. Sales tax is collected where applicable. If sales tax is not charged at checkout, customers may still be responsible for use tax based on their state’s regulations. We encourage customers to check with local tax authorities for specific guidelines. This tax notice is for informational purposes only and does not constitute legal or financial advice. Please consult a tax professional for guidance.

At Grand Caliber, we want every customer to shop with confidence.

All returns must be pre-approved and shipped using an insured, trackable method. Once received, the watch will be inspected for wear or damage. If approved, a refund will be processed to the original payment method within three business days. Grand Caliber does not offer cash refunds. If a return package is lost in transit, an insurance claim must be completed before a refund is issued. For any questions regarding returns, please contact our team before finalizing your purchase.
