If you’re looking for a luxury watch that’s also a solid investment, then Rolex is the right brand for you. Well-kept models only increase in value over time. Rare, vintage models sell for five or six figures at auctions. The introductory model, Oyster Perpetual, is available used for around 1,000 euros. Unworn, it’s available for about 3,000 euros. The Submariner, one of the most well-known watches out there, costs around 5,000 euros used. Rarer models, like the so-called “Red Sub” with reference number 1680, cost more than 30,000 euros. The COMEX-Submariner, which Rolex developed for the French company Compagnie maritime d’expertises, is in a similar price range. Unworn, new Submariners cost around 6,000 euros. The Daytona models start at around 8,000 euros, while Paul Newman Daytonas exceed 100,000 euros. These watches, with reference number 6239, are recognizable thanks to their contrasting, red seconds scale.
