Chrono Lab - Luxury Watch Quiz

801 questions. 272 watches. 80+ houses. A new quiz every morning, a story to unlock, a collection to build. Offline, no account, no ads.

Think you know watches? Prove it.

Chrono Lab turns watch knowledge into a real challenge: identify a reference from a close-up, guess what it sold for, and build a collection one question at a time. 548 questions and 194 watches free — 801 questions and 272 watches with every premium pack.

DAILY WATCH Every morning, a new quiz drawn from the whole catalogue — no two days alike. Finish it to unlock the Watch of the Day: a short story about one legendary timepiece, revealed only once. 160 stories, one per day. Keep your streak alive.

DISCOVERY MODE 54 themed packs built as real horology courses — Rolex Essentials, Dive Watches 101, Chronograph Masters, The Holy Trinity, Grand Seiko Deep Dive, Haute Horlogerie, and 48 more. Each runs from the basics to genuine expertise.

CHALLENGE MODE Timed questions, one category, one personal best to beat. Every session pulls a different set.

IDENTIFY THE WATCH A close-up photo. Several choices. One correct answer. Progressive hints if you're stuck. The advanced variants show only the movement, the case back, or a single dial detail. This is where real expertise is tested.

COLLECTION BOOK Every watch you meet joins your collection — a visual catalogue you unlock progressively, with exact references, calibers, materials and the facts worth knowing. From Rolex, Patek Philippe and Audemars Piguet to Grand Seiko, Nomos and F.P. Journe: 80+ houses, all with real reference numbers.

PROGRESSION Earn XP on every correct answer. Rise from Novice to Grand Complication. Unlock 29 badges by mastering brands, holding streaks and proving your speed.
