Movement serviced and is accurate & strong. Date quickset works as it should. Original dial with spots of tropicalization around markers 10, 11, 12, 2, and 3/date window. They're not visible to me by the naked eye, even in strong light, but they are there. Dial lume appears to be original, dial is "T" marked, lume shows some patina, but will glow weakly for a time.Handset is immaculate and looks to be an older service handset. It glows more than the dial, but neither the dial or the hands glow as strongly or for as long as my 16610. Insert appears to be a service one, based on the age of the watch, but probably an older one. Case has been polished but still is nice and beefy. All new seals, case and bracelet are fully cleaned and shiny. Bracelet is full-length and more. This the JB Champion-made oval-link with 14k center links. These were fitted to some watches in this time period by Rolex to get around tariffs on completed watches. Bracelets were made by manufacturers in the target countries and fitted after importation.
