Step 1: Identify the Correct Product Listings

Before using Superbuy, you’ll first locate the Longines model you want in Weidian Shops. On this platform, independent or authorized retailers often list new or pre-owned luxury watches at competitive prices. It is crucial to meticulously examine seller reputations, customer feedback, and watch specifications. Authenticity and condition should be your top priorities.

Always cross-reference the product details with an external spreadsheet resource, such as the one available here: https://findsspreadsheet.com/. This detailed database provides up-to-date information on various luxury watch models, sellers, prices, and special tips. Use this spreadsheet primarily to verify product codes, available discounts, seller credentials, and most importantly, to avoid dubious or counterfeit listings within Weidian. Research done here saves time and ensures you invest in a genuine timepiece.

Step 2: Register Your Superbuy Account

If you don’t already have an account, sign up on both the Superbuy website or mobile app. Usually, registration is fast and requires just an email address and password. After completing it, make sure your account is verified. Once logged in, update your personal shipping address under ‘My Superbuy’ in the dashboard so the agent can later forward the product to you internationally without hassle.

Step 3: Submit Your Purchase Request

On the dashboard, locate the ‘Order Submission’ or ‘Add to Cart’ options. To purchase using Superbuy's service, you simply copy the product page URL of the selected Longines watch from the Weidian merchant and paste it into Superbuy’s search bar or order form.
Proceed to insert any critical specifications like color, size, or product variations in the notes section to ensure Superbuy buys exactly what you intend. Note that payment on Superbuy’s site is typically doable in multiple currencies via cards, PayPal, or other widely accepted payment options like Alipay.

Step 4: Processing and Warehouse Handling​

After payment, Superbuy will procure the item on your behalf. Once acquired from the Weidian seller, your item is shipped to Superbuy’s secure warehouse facility in China. Here, each product undergoes a thorough quality check. Critical details like seller communication, tracking updates, photos of the physical watch received in the warehouse – all these can be managed through your Superbuy account under “Warehouse” or “My Parcels.”

When Longines watch arrives, staff will inspect the watch for damages, consistency, included accessories, and perform authenticity assessments based on your requirements. Superbuy is known for taking detailed photos from multiple angles for customer clearance before shipment abroad.

Step 5: Consolidate and Ship Internationally

After you've validated your product via Superbuy's QC photos, you can prepare your item for international shipping. Inside a Superbuy account, you have multiple options: request gift-wrapping, combine items in one parcel, simplify packaging to cut costs, or remove original commercial tags.

The procedure includes entering your overseas destination address again, then picking a preferred international courier such as DHL, EMS, FedEx, or ePacket. This selection can depend on desired shipping speed and costs. Recommended: choose insured shipping to protect a high-value item like a Longines watch.
