Panerai watches are produced in limited numbers because they must meet quality standards which are much higher than for most watches, typical of equipment designed for military use. The main requirement is reliability, which is vital. A user's life may depend on this, and it may be put at risk by a watch's failure or imperfect assembly.
The Panerai Luminor watch is guaranteed to 300 meters and is actually tested to resist a pressure of 40 atmospheres, which is one-third greater and equivalent to a depth of 400 meters.
