Edelson Lechtzin LLP is investigating Swatch Group for potential consumer overcharging. The firm is examining if the company failed to refund customers after the Supreme Court ruled U.S. tariffs unlawful on February 20, 2026.

Investigators allege Swatch raised retail prices to offset tariff costs but maintained those prices after the court's decision. The probe covers all 16 of the company’s watch and jewelry brands.

Prominent brands under review include Omega, Longines, Tissot, Blancpain, and Harry Winston. No formal lawsuit has been filed, and no court has found any wrongdoing at this stage.
