What it does
Daily Watch
A new quiz every morning, drawn from the whole catalogue. Finish it to unlock the Watch of the Day — a short story about one legendary timepiece, revealed only once. 160 stories, one per day.
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.
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, with progressive hints. Advanced variants show only the movement, the case back or a single dial detail.
Collection book
Every watch you meet joins your visual catalogue — exact references, calibers, materials and the facts worth knowing.
Progression
Earn XP on every correct answer, rise from Novice to Grand Complication, and unlock 29 badges by mastering brands, holding streaks and proving your speed.
80+ houses, all with real reference numbers — from Rolex, Patek Philippe and Audemars Piguet to Grand Seiko, Nomos and F.P. Journe.
