Flyback.ai

Flyback.ai is a buy-side intelligence platform built specifically for the luxury watch secondary market. It solves a fundamental problem: asking prices are unreliable noise. Sellers price optimistically, buyers overpay, and genuine deals vanish before most people notice. Flyback fixes this with AI. It aggregates listings from over 20 global marketplaces and dealers including eBay, Chrono24, Jomashop, Watchfinder, DavidSW, Subdial, Timepeaks Japan, and more. Every listing is scored in real time against machine learning models trained on hundreds of thousands of verified sold transactions. The result is an objective deal score from 0 to 100 that tells you whether a listing is priced fairly, above market, or genuinely underpriced. Unlike static price trackers, Flyback's models are trained exclusively on what watches actually sold for, not asking prices. This distinction matters: a watch listed at $8,000 means nothing without knowing that comparable pieces sold for $6,200 last month. Flyback is designed for collectors, enthusiasts, and first-time buyers who want to make informed purchasing decisions without spending hours cross-referencing prices across multiple sites. The platform also includes a unique wrist fit tool that uses lug-to-lug measurements and case curvature data to tell you which watches will actually wear well on your wrist. Flyback is free to use and covers over 2,300 watch references across 32 major brands including Rolex, Omega, Patek Philippe, Audemars Piguet, Cartier, Tudor, and more.

Real-Time Deal Scoring Across 20+ Sources

Every listing from eBay, Chrono24, Watchfinder, Jomashop, Bezel, DavidSW, Timepeaks Japan, Yahoo Auctions Japan, Subdial, The 1916 Company, Tourneau CPO, and more is automatically scored in real time. The deal score ranges from 0 to 100 and is calculated by comparing the listing price against comparable sold prices, seller reputation, condition, completeness of box and papers, and current market velocity. This gives you an instant, objective assessment of whether a deal is worth pursuing.

Fair Value Forecasts with Confidence Ranges

Flyback's machine learning models estimate fair value for qualifying listings, adjusted for condition, box and papers, seller history, and market trends. These forecasts are trained on thousands of real transactions, not asking prices. The model outputs a fair value range with confidence intervals, so you know not just the estimated price but how reliable that estimate is. This helps you avoid overpaying and identify underpriced opportunities before they are snapped up.

Historical Price Trends by Reference

For each watch reference in the catalog, Flyback provides historical price trend data showing how prices have moved over time. You can see average sold prices by month, identify seasonal patterns, and understand whether a particular model is appreciating or depreciating. This feature is essential for making investment decisions and timing your purchases strategically. The data is drawn from actual sales, not listings, giving you an accurate picture of market behavior.

Personalized Wrist Fit Analysis

Flyback's wrist fit tool is powered by a reference catalog covering over 2,300 watch references with 100% lug-to-lug measurement coverage. Enter your wrist circumference and the platform recalibrates deal scores based on lug-to-lug fit. It adjusts for lug curvature type including straight, curved, or integrated lugs. This means you no longer have to guess whether a 42mm watch will wear well on your 6.5-inch wrist. The tool tells you which watches will actually fit comfortably before you buy.

Identifying Undervalued Watches Before They Sell

A collector looking for a specific Rolex Submariner reference can use Flyback to scan all 20+ marketplaces simultaneously. The deal score highlights listings that are priced below market value based on recent comparable sales. Instead of manually checking each site and guessing at fair prices, the AI surfaces the best opportunities instantly. This allows serious collectors to act fast on genuine deals that would otherwise be invisible amid thousands of optimistic listings.

Evaluating a Watch Purchase Decision

A first-time luxury watch buyer considering a Tudor Black Bay can use Flyback to check whether a listing is fairly priced. The fair value forecast shows the estimated price range based on the watch's condition, whether it includes box and papers, and the seller's reputation. The buyer can see historical price trends to understand if the model is currently overvalued or undervalued. This removes the anxiety of overpaying and gives the buyer confidence in their purchase.

Building a Watch Collection Strategy

An investor building a portfolio of luxury watches can use Flyback's market trends dashboard to track average sold prices and volume shifts across brands and segments. They can identify which brands are appreciating, which references are becoming scarce, and where market velocity is increasing. This data-driven approach replaces guesswork with actionable intelligence, helping the investor allocate capital to watches with the strongest investment potential.

Checking Wrist Fit Before Buying Online

A buyer with a 6.25-inch wrist who is considering a 44mm Panerai Luminor can use Flyback's wrist fit tool before making a purchase. The tool checks the lug-to-lug measurement and lug curvature type against the buyer's wrist size. It tells the buyer whether the watch will wear comfortably or look oversized. This prevents costly mistakes and returns, especially for buyers who cannot try on watches in person due to geographic or availability constraints.

How does Flyback calculate the deal score?

The deal score is calculated using a machine learning model that compares a listing's price against comparable sold transactions for the same reference. The model considers multiple factors including the seller's reputation score, the watch's condition (new, pre-owned, damaged), whether it includes box and papers, and current market velocity. Scores range from 0 (overpriced) to 100 (exceptional deal). The model is trained exclusively on verified sold data, not asking prices, so the score reflects real market value.

What sources does Flyback monitor?

Flyback aggregates listings from over 20 global marketplaces and dealers including eBay, Chrono24, Watchfinder, Bob's Watches, WatchMaxx, Bezel, Jomashop, DavidSW, Timepeaks, Yahoo Auctions Japan, Subdial, The 1916 Company, Tourneau CPO, European Watch, AuthenticWatches, Birmingham Luxury Watches, and Jared. New sources are added regularly to expand coverage across different regions and market segments.

Yes, Flyback is completely free to use. There are no subscription fees, no paywalls, and no hidden charges. You can browse deals, check deal scores, view historical trends, and use the wrist fit tool without paying anything. The platform generates value by providing objective market intelligence that helps buyers make better purchasing decisions.

How accurate is the wrist fit analysis?

The wrist fit analysis is powered by a reference catalog with 100% lug-to-lug measurement coverage across over 2,300 watch references from 32 brands. The tool adjusts for lug curvature type including straight, curved, or integrated lugs. Accuracy depends on entering your correct wrist circumference. The analysis tells you whether a watch is likely to fit comfortably based on case dimensions and your wrist size, but individual wrist shape and personal preference also play a role.
