Retail vs market
For sport models in stainless steel, market price has historically run above retail - often substantially so during the 2020–2022 cycle. For precious-metal references and most Datejust/Day-Date dial variants, market price typically sits at or below retail.
What drives premiums
Stainless steel, classic bezel material (rather than two-tone), original 'box and papers', recent service history, and discontinued reference status (e.g., 'fat lady' Daytonas, 'Hulk' Submariners) all push prices up.
What drives discounts
Polished cases (lugs no longer sharp), aftermarket bracelet links, missing papers, service replacement parts (especially dials and hands), and recent collection-wide refreshes that make the prior generation visually dated.
