A Patek Philippe Nautilus is up 154% in resale value. A Cartier Demoiselle is up 80%. Even the more modest movers on the list, the Cartier Tank Américaine and Tank Française, are up 43% and 39%. These aren’t projections or wishful collector talk, they’re figures straight from eBay’s own Watchlist Trend Report, tracking the first quarter of 2026. Overall listings in the platform’s global jewelry and watches category jumped nearly 20% in the same period. That old watch sitting in a drawer, inherited or bought secondhand years ago, might be worth meaningfully more than whoever last checked assumed.

Why Watches Are Suddenly Outrunning Handbags

Fashion resale gets most of the headlines, but the eBay data suggests watches are quietly one of the strongest-performing categories on the platform. eBay’s report puts it plainly: “Watches continue to gain value as style statements and long-term investments. Cartier’s continued dominance, alongside models like the Patek Philippe Nautilus, reflects growing demand for timeless, recognizable pieces that hold cultural and resale value.” That framing, watches as both fashion object and investment vehicle, is a shift from how most people have historically thought about the category, which used to be dominated by pure horology enthusiasts rather than everyday secondhand shoppers.

Cartier’s Quiet Dominance

What’s striking about the Cartier numbers specifically is how many different models are moving at once. The Demoiselle, Tank Américaine, Tank Française, Baignoire, and Ballon Bleu are all up double digits, ranging from a 21% bump on the Baignoire to that 80% jump on the Demoiselle. That’s not one lucky style catching a viral moment. That’s a whole brand catalog appreciating simultaneously, the kind of broad-based demand that’s much harder to fake or hype into existence than a single trending item.

The Nautilus Outlier

The Patek Philippe Nautilus, at 154%, is the standout figure in the entire report, and it’s worth noting why that particular watch has become such a resale magnet. Originally released decades ago as a somewhat unconventional steel sports watch from a brand associated almost exclusively with formal, precious-metal pieces, the Nautilus has spent years building a reputation as one of the hardest luxury watches to acquire new, which pushes serious demand directly into the secondary market. A 154% jump in a single quarter suggests that scarcity dynamic isn’t easing up, it’s intensifying.

The Nautilus, Explained

It’s worth understanding why the Nautilus specifically became this kind of magnet. Patek Philippe spent most of its history making formal dress watches in gold and platinum, the kind of pieces you’d wear with a suit rather than a wetsuit. The Nautilus broke from that entirely, a steel sports watch with a porthole-shaped case that looked almost casual next to the rest of the brand’s catalog when it debuted. That contrast, a luxury house’s most prestigious name attached to its most unexpected design, is exactly the combination that tends to age into the strongest resale demand: familiar enough to be trusted, different enough to be memorable.

What a 20% Listing Increase Actually Signals

The category-wide listings jump matters as much as any individual model’s price movement. Nearly 20% more jewelry and watches hit eBay’s global marketplace in Q1 2026 alone, which means more sellers are recognizing that what’s sitting in a jewelry box or a drawer has real resale value worth chasing right now, not five years from now when trends might have shifted again. Supply and demand are both climbing together, and prices are still moving up regardless.

The Pattern Worth Remembering

Handbags and sneakers get the viral resale headlines because they’re easy to photograph and easy to hype. Watches move more quietly, but the eBay data suggests they’re appreciating just as fast, sometimes faster, precisely because they were never designed to chase trends in the first place. A watch that was built to last decades is now proving, in resale numbers, that it can also appreciate across them. Next time you’re clearing out a jewelry box or sorting through an inherited collection, that quiet corner of the resale market is worth a second look before anything gets donated or set aside as an afterthought. A brand name and a model number, checked against listings like these, might be the difference between a donation bin and a genuinely significant sale.
