At the world’s biggest and most important event for the watch and jewellery industry, Baseworld 2010 (during 18-25 March 2010 in Switzerland), Glashütte Original will present their rose gold Pocket Watch No. 1 with quarter hour repetition in a limited edition of 25 pieces.
One particularly striking feature of this watch is the quarter-hour repetition, which announces the quarter hours and hours acoustically.
Using one tone, the repetition first of all indicates the previous hours, and then, by means of a second and higher tone, the number of quarter hours that have elapsed since the last full hour.
