Brand names, logos, and trademarks referenced on this website are the property of their respective owners and are used solely for identification purposes.
Product descriptions, specifications, and photographs are provided for informational purposes and represent our best effort at accuracy. Minor variations between photographs and the actual product may exist due to lighting, screen calibration, or the inherent limitations of photography. Such variations are not grounds for a return or dispute.
3. Pricing and Payment
All prices are listed in United States Dollars (USD) and are subject to change without notice until payment is confirmed. A listing price does not constitute a binding offer until accepted and confirmed by Ultimate Diamond.
- We accept payment by bank wire transfer, cash (in person), and major credit cards. Pricing may vary by payment method.
- Payment must be received in full and cleared before any merchandise is shipped or released.
- For wire transfers, the watch will be shipped upon confirmation of cleared funds by our bank.

4. All Sales Final
All purchases are final and non-refundable. We do not accept returns or exchanges except under our Authenticity Guarantee as described in our Return & Refund Policy. By completing a purchase, you acknowledge and agree to this policy.
5. Authenticity Guarantee
Every watch sold by Ultimate Diamond is guaranteed to be 100% authentic. All watches are inspected and authenticated by our in-house watchmakers before sale. If a watch is determined to be inauthentic by an independent, certified horological authority, Ultimate Diamond will issue a full refund of the purchase price, subject to the conditions outlined in our Return & Refund Policy. This guarantee has no expiration.

- Damage or alteration caused by service performed by anyone other than Ultimate Diamond or an authorized service center
- Normal wear and tear, including battery replacement for quartz movements
- Straps, bracelets, clasps, crystals, or crowns unless directly caused by a movement defect
Warranty claims are handled as a repair service at our sole discretion. We may repair, replace the movement, or provide a functionally equivalent remedy. The warranty does not entitle the buyer to a refund or exchange.

- All shipments are fully insured and require a signature upon delivery.
- Risk of loss transfers to the buyer upon delivery to the shipping carrier.
- Ultimate Diamond is not responsible for delays, losses, or damage caused by the shipping carrier after the package has been tendered to the carrier.

- It is the buyer's responsibility to provide an accurate shipping address. Re-shipment costs for incorrect addresses are the buyer's responsibility.
8. Selling Your Watch to Us

- Final purchase price is determined upon physical inspection of the watch at our premises and may differ from the preliminary quote.
- You represent and warrant that you are the lawful owner of any watch you offer to sell and that it is free of liens, encumbrances, and any claims by third parties.
- Payment for purchased watches is made by wire transfer or check upon completion of inspection and acceptance.
