评论 [Review]
Most manufacturers’ diving meters usually indicate the diving depth in units of standard atmospheric pressure, so the 30 meters, 50 meters, 100 meters, or 200 meters that often appear on the dial can only be measured by the concept of ‘theoretical value’, which is difficult to compare with the real ‘Into the water’ establishes a direct connection in depth. IWC set a precedent for adjusting the built-in diving chronograph lap with the crown in the 1960s.
IWC “Deep Sea One” was born in 1999. It is the first watch equipped with a mechanical depth gauge with a measuring depth of 45 meters. Its principle is to mark the watch’s water entry through a spring tube that can sense the external water pressure. depth. The movement of this watch is modified from the Jaeger-LeCoultre 891 movement, while the mechanical depth gauge is installed separately. Due to its high cost and small audience, IWC produces only a small number of Deep One watches, which have become hot among collectors.
