That Watch vs ChronoDNA

That Watch is the precision-crafted companion for watch collectors. Catalog your collection, log every wear, measure accuracy like COSC, and discover insights you never knew about your watches. VAULT — YOUR DIGITAL COLLECTION Add watches by searching our catalog, use Smart Search to identify any timepiece instantly, or add manually. Store full specs, multiple photos, purchase details, and custom names. Mark special and limited editions with their edition number. Organize watches into Watchboxes and share them as beautifully designed cards. COLLECTION VALUE — WHAT IT'S ALL WORTH Record what you paid, the list price, and what you believe each watch is worth today. Your collection total is a single figure in your own currency — no exchange rates, no guesswork — and every watchbox shows what's inside it. Where you haven't set a value yet, we fall back to catalog pricing and tell you exactly how many watches the total covers. PART WITH A WATCH, KEEP THE RECORD Sold, gifted, or simply put away — mark it and the watch keeps everything. Wear history, photos, and purchase details all stay intact, and a sold watch shows the gain or loss against what you paid. Your vault shows what you own now; your history shows everything you've owned. WRISTCHECK — EVERY WEAR, TRACKED Log which watch you wear each day. View your history on a week strip or full month calendar. Build streaks, track rotation, and see your diversity score — a measure of how evenly you wear your collection. ACCURACY — EVERY SECOND, MEASURED Measure your watch's accuracy with a tap-based interface inspired by professional COSC testing. Track rate by position (dial up, dial down, crown up, and more), view offset and rate charts over time, and see how your watches perform against chronometer standards.
