Ask the seller for original service paperwork or stamped warranty/service invoices showing: the service provider name, date, listed interventions movement overhaul, crystal, seals, strap, and any short-term service warranty. If those documents are missing, request clear photos of the paperwork and any retailer/service-stamp on the warranty card before buying.

1 What to request first
Request the original service invoice and any warranty card or service-stamp. The invoice should name the service provider, list work completed parts replaced, movement service, and give dates. Ask whether the watch was serviced by an authorized Hamilton/Swatch Group service centre or an independent watchmaker and request contactable proof shop header, stamp or invoice.
2 What authorized service records usually include
Hamilton and its official service centres typically provide a dated invoice, a brief description of interventions, and a service warranty period noted on paperwork or on the brand’s customer portal. Authorized services may also update Hamilton’s internal records when the warranty/service is performed.
3 How to read entries and dates
Look for explicit dates service received and completed, clear itemised work clean/overhaul, mainspring, crystal, gasket replacement, pressure test, and the technician/shop name or stamp. Ambiguous notes like "checked" or "cleaned" without date or provider are weak evidence of substantial intervention.
4 Independent vs. authorized notes — what matters
Independent watchmakers often supply detailed technical notes; authorized Hamilton centres will add brand-specific forms or stamps and may carry a short service warranty. Both can be legitimate; prioritize clarity who did the work, exact parts changed over whether it’s an independent or branded stamp.
5 Practical red flags and final questions
Red flags: no dated paperwork, generic receipts without line items, handwritten notes without a shop name, or claims of "recent service" with no proof. Ask for before/after photos, part numbers if parts were replaced, and whether pressure testing was performed if water resistance matters.
