Gruen buying policies
Public summaries. The selling dealer's posted policy is authoritative.
Authentication
All Gruen listings shown on MostExpensiveWatches are tracked from vetted secondary-market dealers. Authentication is the selling dealer's responsibility — for Gruen specifically, confirm serial-to-reference alignment, box-and-papers if claimed, original bracelet links, and movement integrity. For modern pieces, verify the original guarantee card is dated and stamped.
Shipping
Shipping, insurance, duties, and import handling vary by the selling dealer. International buyers should confirm with their local customs broker before committing — luxury watches over $5,000 often require declared insurance and may attract import VAT or duty.
Returns
Return windows vary by dealer (typically 3–14 days for inspection-only returns). Confirm directly with the listing merchant before purchase. MostExpensiveWatches does not process returns directly.
Valuation
Gruen secondary-market prices move with auction comps, production volume signals, and dealer inventory turns. The range shown reflects current live listings — historical auction hammers may sit higher.
