Rolex Day-Date 1803 'No Lume Japan'


A very clean and sharp Rolex Day-Date reference 1803 from 1969. This watch has a 'no lume' dial, which means that - despite the T Swiss T signing below the 6-hour position - the dial and hands don't contain tritium. Back in the day, many Asian countries had import restriction regarding luminescent material (since it's slightly radioactive). This example was made for the Japanese market, as is evidenced by its bracelet which bears a 'Made in Japan' signature in the clasp. Because many countries had heavy import taxes on gold, Rolex often chose to produce the cases and movements in Switzerland but the bracelets locally.
