Notes

Property of The Original Asian Watch Collector

The IWC Deep One, introduced in 1999, was the first wristwatch equipped with a mechanical depth gauge that showed depth up to 45 meters. The mechanical depth system is a Bourdon tube which acts as a pressure-sensing element. When water enters the coil tube, it causes the tube to rigidify. The pressure is then indicated by a depth gauge hand in white. A yellow hand indicates the greatest depth during a dive. A pump was furnished with the watch to test the pressure gauge. The Deep One was made for a very short period in limited production due to its high cost of fabrication and relatively small market and the watch was rapidly discontinued.

This lot is accompanied with a full set of accessories that shall be eyed upon by many IWC lovers and divers watch enthusiasts.
