What's inside
Everything a collector needs
Five focused tools built around how watch enthusiasts actually think about their pieces.
Watch Box
Your full collection in a clean grid. Add photos, reference numbers, case details, and notes. Sort by brand, most worn, or recently added. Favourites always float to the top.
Wear Log
Record which watch you wore each day, with optional occasion tags and notes. Wear multiple watches in one day — Lumed tracks them all.
Stats
See your collection at a glance — most worn pieces, neglected watches, and monthly activity across 30 days, 90 days, or all time. Know which watch needs a wrist day.
Time Sync
A live, NTP-synced clock accurate to the millisecond — so you can set your watch with precision. Add world time zones to check across cities at a glance.
Accuracy Tracking
Photograph your watch face — Lumed reads the EXIF timestamp and compares it to NTP time to calculate daily drift in seconds. Track whether it's gaining or losing over time.
Photo-based measurement
Know your drift, down to the second
Point your camera at any watch face. Lumed extracts the time from the photo's EXIF metadata, compares it against an NTP reference, and plots your movement's daily rate over time. No external hardware required.
