01 / CONDITION LADDERFour bands.
Four bands.
Evidence decides.
The condition ladder is a decision model, not an automated appraisal. A physical problem can outweigh every accessory; strong provenance cannot repair a weak watch.
The normal decision band for an honest, correctly described example with no material ownership surprise.
Visible wear, incomplete set or weaker transaction terms can be acceptable when the price absorbs the friction.
Deferred service, damage, parts uncertainty or weak seller evidence require manual review rather than blind discounting.

Current-production supply and retail discounting keep the pre-owned market disciplined. Full sets, warranty, complete links and strong bracelet condition support the upper band.

Supply is healthy. Bracelet scratches, missing links, warranty, complete accessories and pricing too close to retail explain most weak transactions.
