That Watch

Curate. Wear. Measure. Discover. The watch collector's companion — crafted with the same attention to detail you expect from your timepieces.

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. Organize watches into Watchboxes and share them as beautifully designed cards.

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.
