Watch Marketplace Authentication Checklist Overlay

WHAT IT DOES

Watch Marketplace Authentication Checklist Overlay scans the current page for watch listings, extracting brand, model, reference number, price, condition, and seller information from marketplace pages (Chrono24, eBay, etc.). The floating panel displays an authentication checklist covering key verification points including movement, case, dial, crown, bracelet, serial number, and documentation. Each listing has a checkable checklist with notes, and watches with complete documentation are highlighted. Authentication notes can be saved and shared, and authentication data can be exported as CSV or text for reference. Authentication status is tracked across listings with a summary score for each watch.

WHERE IT RUNS

Works on any watch marketplace page, including Chrono24, eBay, WatchBox, and other watch selling platforms. The script detects watch listings using common selectors and can also fall back to general item cards. It works best on pages with structured listings containing brand, model, and price information.

HOW TO USE

The panel displays a checklist for each detected watch. Select a watch from the dropdown to view its checklist. Check or uncheck items to track authentication progress. Add notes to individual checklist items for detailed observations. The status summary shows completion percentage with color-coded indicators (green for complete, yellow for partial, red for incomplete). Reset the checklist for any watch, or clear all authentication data. Export the checklist as text for reference or sharing. The panel automatically saves your progress as you check items.

MECHANISM — WATCH EXTRACTION WITH AUTHENTICATION CHECKLIST TEMPLATE

The script extracts watch listings using a multi-strategy approach. It first attempts to find listing containers using common marketplace selectors (.listing, .item, .product). From each container, it extracts title, brand, reference number, price, condition, and seller using targeted sub-selectors. The brand is detected by matching against a database of known watch brands. The authentication checklist uses a template that can be customized in settings, with items covering movement, case, dial, crown, bracelet, serial number, and documentation. Each item can be checked and annotated, and the checklist status is calculated as the percentage of checked items. All checklist data is stored locally and persisted across sessions.

THE PANEL

The floating panel is fully draggable and remembers its position per domain. Click the minimize button to collapse it to a small bubble, or press Escape to hide it. The panel automatically adjusts to different screen sizes and can be resized to show more content. All settings and authentication data are saved per domain. The panel integrates smoothly with any page layout using the BGPanel framework, maintaining clean separation from page content.

PLEASE NOTE

This script requires the free BotGentz extension to run. It does not send any data to external servers; all extracted watch data, checklist status, and notes remain entirely local to your browser using GM_setValue. The script never reads password fields, hidden inputs, or file inputs. It stores only watch titles, brands, reference numbers, prices, seller information, and user-entered checklist data from publicly visible page content. Listing detection depends on the page structure; if watches are not detected, use the "Scan Listings" button to refresh extraction. The authentication checklist is a guide only and does not replace professional authentication. Data persists across browser sessions and is isolated per browser profile.
