Buyer tip

Tudor Black Bay GMT and Grand Seiko GMTs are the value champions; Rolex GMT-Master II sells above list pre-owned.

Buying in Europe: authorized-dealer prices for Swiss watches are set per country and include VAT; a watch bought in Switzerland or the EU carries the same international warranty as one bought in the US. Grey-market and pre-owned prices are often quoted in euros or Swiss francs.

Luxury prices move in a different rhythm from everyday shopping. The great houses (Chanel, Hermès, Louis Vuitton, Dior, Rolex) raise prices once or twice a year, often in January and in spring, and almost never discount their icons. Seasonal pieces, colors and many shoes, coats and knitwear drop 30–50% in the end-of-season sales in January and from late June. Watches from brands such as Omega, TAG Heuer, Longines and Breitling, and most fragrance, see the best prices around Prime Day and Black Friday. Judge any deal against the usual price we show.
