About Mainplate

Whether you flip vintage watches on weekends or maintain a carefully curated personal collection, managing your watches has never been this clean, this smart, or this satisfying. Mainplate is the all-in-one dashboard built for watch enthusiasts, hobbyist flippers, and professional watchmakers. Track every deal, log every service, know your real numbers — and never lose sight of what your time is actually worth. DASHBOARD — The Full Picture One screen. Total capital deployed. Realised profit. Average ROI across all flips. Open inventory value. Everything you need to understand your watch business at a glance. Sync precisely your wristwatch with the atomic clock. YOUR COLLECTION — Every Watch, Every Detail Your personal watches deserve more than a spreadsheet. Document each piece with photos, purchase price, a full service diary, and a running cost breakdown. When you sell, Mainplate calculates your gain or loss instantly. A dedicated Wishlist tab keeps your dream watches organized and ready to promote to your active collection at any time. FLIP TRACKING — Know Your Real ROI Every flip is a complete financial record. Log the purchase price, add expenses as you go, track your labor hours at your configured hourly rate, and let Mainplate crunch the numbers. The moment a flip is marked as Sold, you get net profit and ROI % — automatically, no math required. A four-stage workflow (Acquired → In Progress → For Sale → Sold) keeps your open pipeline and closed deals neatly separated, with color-coded status throughout the app. TIMEGRAPHER LOG — Precision at a Glance Record timing readings across all six standard positions (DU, DD, 3U, 6U, 9U, 12U), amplitude, and beat error. Mainplate computes the delta automatically and flags anomalies with color-coded diagnostic warnings — so you know exactly whether a movement needs attention before or after a service. INVENTORY & EQUIPMENT — Your Workshop, Counted Parts, oils, gaskets, tools — tracked with quantity and value per item. Log entries on a flip can auto-sync to your inventory, keeping stock accurate without extra effort. Your equipment gets its own dedicated section with a running total value. MORE FEATURES YOU'LL ACTUALLY USE • Photo gallery with drag-to-reorder and full lightbox viewer • Inline editing — update watches and flips directly in the list, no extra navigation • Light & dark mode • Multiple currencies, and custom category colors & icons Mainplate started as a free, open-source web app loved by the watch community.
