How to care for your Longines
A Longines is built to outlast its owner — but how it's treated decides whether it holds value as an asset or quietly loses it. The habits below cost almost nothing, and one theme runs through all of them: originality is value. Most 'improvements' owners make to watches reduce what dealers will pay.
Caring for a Longines: what matters most
Modern Longines uses robust, widely serviceable movements — servicing is affordable and any competent watchmaker can maintain one, which keeps ownership easy. Standard rules apply: five-to-seven-year services, fresh seals with battery changes on quartz models, and pressure tests before swimming with a HydroConquest.
Vintage Longines demands the opposite of casual: the great mid-century calibres deserve a specialist's touch, and value lives in original dials and unpolished cases. More vintage Longines value has been destroyed by well-meaning 'restoration' than by neglect.
Longines care checklist
- Never redial a vintage Longines — original dials, even aged, carry most of the collector value.
- Have vintage chronograph calibres serviced only by watchmakers who know them.
- Keep modern service simple and documented; receipts support resale.
- Don't polish vintage cases; thin mid-century lugs disappear fast under a wheel.
- Store leather-strapped dress models dry and out of sunlight.
The universal rule: don't polish
Polishing removes metal — every pass softens case lines and rounds edges, permanently. Dealers and collectors pay premiums for unpolished watches and discount refinished ones. Honest scratches are expected and priced in; missing metal is forever. If you're preparing the watch for sale, clean it gently and stop there.
