Pre-Purchase Watch Inspection Checklist
=======================================
A step by step checklist for inspecting a fine watch, its paperwork, and the seller before you commit, whether you are at a boutique, a pre-owned specialist, or a private meeting.

[ ] Write down the exact reference number, dial configuration, and production years for the piece, and save photos of known correct examples to compare against on the spot.
[ ] Fix your all-in ceiling including sales tax, any shipping or platform fees, a strap or bracelet adjustment, and a first service reserve, and decide in advance that you will walk away above it.
[ ] Ask the seller in writing, before the appointment, whether the watch has been polished, serviced, or fitted with replacement parts, and by whom; a vague answer is itself a data point.
[ ] Bring a loupe, a soft cloth, a small flashlight, and a notebook, and ask permission before handling or photographing the watch.
[ ] Check case edges and lug bevels for crisp, even lines; softened corners, uneven brushing, or a mismatched finish between surfaces suggest heavy polishing.
[ ] Verify the serial and reference numbers are present, correctly placed for that reference, and match the paperwork; compare engraving depth and font against your reference photos.
[ ] Examine dial printing, indices, and lume under the loupe for crisp edges and even application, and compare lume color on the hands and dial, since a mismatch often means replaced parts.
[ ] Confirm the hands, crown, crystal, and bezel insert are the correct style for the reference and its production period, and ask the seller to account for any deviation.
[ ] Inspect the crystal for chips and deep scratches, and the caseback for tool marks around the notches that indicate repeated or careless opening.
[ ] Wind the watch and set the time and date, feeling for smooth crown action, a clean date jump, and no grinding or excessive play in the stem.
[ ] Through a display back, look for the correct caliber number, consistent finishing, and no rust, scratched screw heads, or debris; if the caseback is solid, ask whether a watchmaker can open it before purchase.
[ ] Ask what accuracy the manufacturer specifies for the caliber and, where possible, have the watch placed on a timing machine and keep the printout.
[ ] Hold the watch by the clasp and let the bracelet hang to check for stretch and sag, then count the links to confirm it has not been shortened beyond what your wrist needs.
[ ] Confirm the end links, clasp, and buckle are original and carry the expected markings; a replacement strap is fine if disclosed, but an original bracelet affects value.
[ ] Match the serial number on the warranty card or certificate to the case, and check that the dealer stamp and purchase date are legible and plausible.
[ ] Inventory the full set: outer and inner box, warranty card, instruction booklet, hang tags, spare links, and any service receipts, and note exactly what is missing.
[ ] For older pieces, ask for a manufacturer archive extract or a service history from the brand or an authorized center, and treat any claimed history with no paper as unverified.
[ ] Photograph the watch, its numbers, and every document before money changes hands so your own provenance file starts on day one.
[ ] Get the return window, the authenticity guarantee, and any remaining warranty in writing, with the name of the person or business standing behind each.
[ ] Pay by a method with buyer protection and a paper trail, never in cash for a private sale of this size, and insist on an itemized invoice that carries the serial number.
[ ] For a pre-owned purchase, budget for an independent inspection by a watchmaker inside the return window and book it before you finalize.
[ ] Sleep on it; if any line above is still unresolved, the right price is the price of a different watch.
