Tsung-Hua Yang, a young Chinese tennis champion, is wearing a Longines Admiral watch. We spotted him with the watch at a press conference from Longines during the French Open tennis tournament at Roland Garros on June 5th 2010. In the famous Tenniseum he proudly showed us his Admiral L3.666.4.56.6, with black dial and stainless steel bracelet. This watch from the Longines Sport Collection has a chronometer, tachymeter, date at 6 o'clock and 42mm case.
