This is a lovely example of the Tudor “Big Block” Automatic chronograph, Reference 79180, circa 1990, in well-preserved condition, and including its original Tudor box and Rolex Service Center warranty card, showing a service by Rolex in 2008 in Japan. The case of this Tudor “Big Block” has been lightly polished in the past, but it retains thick and beefy lugs, and still shows the original bevels in the lugs. The dial is blemish-free and in mint condition. Further, the watch retains its original tritium lume on both dial and hands, aged to a nice creamy yellow. Finally, the watch is fitted on its original Tudor Oyster 78360 bracelet with 589 endlinks, and has 12 full links with minimal stretch.
