A. Lange & Söhne is sold through a deliberately small network of boutiques and authorized retailers, so any listing that advertises "authorized dealer" status deserves a hard second look. This guide walks through how to confirm a genuine point of sale, what counterfeit sellers consistently get wrong, and the paperwork, shipping and return protections you should insist on before money changes hands.

Key Features to Verify Before You Buy

• The dealer's name appears on the brand's own official boutique and retailer list, not only on a banner image.
• A physical street address and a phone number that reaches a person who can answer product questions.
• The full reference number, case material and dial variant stated plainly in the listing.
• Serial and movement numbers shared on request before any payment is sent.
• Original box, certificate and warranty paperwork that match the watch, issued in the buyer's name.
• Payment through a traceable method with a proper itemized invoice.
• A written return window and inspection period in the published terms, not a verbal promise.
• No pressure tactics such as countdown timers or same-hour wire deadlines.

Materials, Movement and Paperwork

Genuine Lange watches carry hand-finished movements, German silver plates, screwed gold chatons and a caseback engraving that matches the certificate exactly. Counterfeit and "replica" listings rarely reproduce those details: watch for mismatched fonts in the dial printing, a caseback number that does not correspond to the paperwork, or a certificate printed on stock paper with a generic signature. When a seller describes the item as a replica, imitation or "mirror quality" piece, it is not an authorized product and no dealer agreement covers it, no matter how the storefront is branded.

Shipping, Returns and Buyer Protection

A legitimate seller ships fully insured with signature-required delivery and states the return window in writing before you pay. If a storefront claims authorization but insists on an untraceable bank transfer, refuses a documented return, or ships without insurance, treat that as a dealbreaker regardless of how good the photographs look.

How do I confirm a dealer is really authorized?

Check the brand's own boutique and retailer locator first, then call the boutique directly using the number published there rather than one copied from the sales page. Ask the seller to confirm their authorization status in writing before you commit.

What are the biggest red flags?

Prices far below the going market, "authorized" claims that exist only on the seller's own website, no verifiable serial numbers, and payment methods with no chargeback rights. Any one of these is reason enough to walk away.
