IWC Ingenieur This wristwatch was made for the first time by IWC in the middle of the 50’s. With its self-winding mechanical movement, it was a sensation at the time, and has always been considered as the most resistant watch. This concept of wristwatch was meant to be constantly adapted to technical progress in the field. 萬國錶 “Ingenieur” — 男仕抗磁自動腕錶 39762 C: 2 D: 2 M: 2, 41 5.500 - 6.500 EUR 6.900 - 8.200 USD 55.000 - 65.000 HKD International Watch Co., Schaffhausen “Ingenieur”, Case No. 2359307, Ref. 5215, Cal. 9520, 49 mm, 89 g, circa 1986 A gentleman’s rare, almost as new Schaffhausen pocket watch with original box, guarantee and papers Case: steel, polished, screwed.

Ingenieur SL Reference 5215 Reference 5215 is part of the “Ingenieur” series and to the best of our knowledge only 200 copies of it were ever made. The model was produced with four different dials - what we have here is known by the collectors as the “Millimeterpapier” or “graph paper”. Not only is this the first anti-magnetic (40,000 A/m) and water-resistant (30 meters) pocket watch ever, it is also the only one to this date. Together with the fact that the watch was produced in a very small series from 1983 to 1996 this makes reference 5215 a much-coveted collectors’ item. 萬國錶 “Ingenieur” — 罕見,保存如新的沙夫豪森男仕懷錶,附原 盒,保證卡及文件 39824 C: 2 D: 2 M: 2, 41, 51 6.500 - 7.500 EUR 8.200 - 9.400 USD 65.000 - 75.000 HKD
