Source note
Cross-verified via hamiltonwatch.com (official), Tourneau, WatchCharts, WatchBase for this exact reference. Confirmed discontinued ("past collection" on Hamilton's own site) -- exact discontinuation year not found, same schema gap noted on the Khaki King entry (id=16). lug_to_lug_mm, bezel_type, and clasp_type not found from any source, left NULL.
Spec backfill (2026-08-08, round 6): dial_color confirmed via Hamilton's own product page title ("Khaki Field Day Date Auto - Dial color:Silver - H70505153", hamiltonwatch.com/en-us/h70505153-khaki-field-day-date-auto.html; direct fetch of this URL timed out, but the page title returned in search results explicitly states the dial color), cross-verified consistently across Jomashop, Watches of America, Watch Warehouse, The Watch Company, Ashford, Sansom Watches, and WatchCharts -- all independently agreeing on "Silver" with no dissent found anywhere. This reference is confirmed discontinued/past collection per the existing note on this row; that status doesn't affect confidence in the dial color spec, which every retailer listing (both current and closeout) agrees on.
