Oris Aquis Depth Gauge, Very Good Condition, Full Set

In the last few years, we have seen quite a few mechanical timepieces featuring a depth gauge. Brands such as IWC, Panerai and Jaeger-LeCoultre all made such instruments. While the tech behind the depth gauge differed from band to brand, they all had one thing in common: a rather high price tag. But there's good news for lovers of high-mech gadgets, since Oris released the exceedingly awesome Aquis Depth Gauge at BaselWorld 2013. Surprisingly, Oris used a hole in the glass to allow water to enter the case in order to measure the depth.
