Genuine Longines Parts & Careful Diagnosis
Accurate diagnosis is essential before replacing components. Our watchmakers inspect the movement, winding system, calendar or chronograph functions, crown, crystal, seals, case and bracelet before preparing an estimate.
Genuine Longines components are used where required and available. For vintage Longines watches, component availability can vary by reference and calibre, so restoration options are discussed individually.
