Collection History
Stingray is one of the most representative professional dive collections in the Memphis Belle catalog, with a 42.5 mm AISI 316L steel case fitted with an automatic helium escape valve — a device typical of watches designed for saturation diving, which allows the gas that builds up inside the case during the ascent from the diving bell to be safely released.
The crystal is a flat sapphire with double anti-reflective coating and a declared hardness of 2000 Vickers, while the movement is a Ronda R150 specifically modified by Memphis Belle, with lubrication options designed to maintain performance even at extreme temperatures.
With a declared water resistance of 50 atmospheres, equivalent to 500 meters, Stingray sits in an intermediate tier between the Memphis Belle catalog's more general-purpose models and its professional saturation divers, such as the Predator Heritage line.
