AI-assisted summary
Description from the seller
This object is a vintage analog depth gauge for divers [5]. It is made by the Italian brand SOS (Strumenti Ottici Subacquei) from Turin [9], a well-known manufacturer that produced high-quality mechanical diving instruments in the 1960s, '70s and '80s and at the time worked closely with top brands such as Scubapro.
Extended description
Independent instrument: It is a mechanical depth gauge (profondimetro) designed to be worn on the wrist like a watch over a wetsuit.
The dial: The meter has a clear cream-white/yellow dial.
The outer scale runs up to 80 meters, which at the time was the standard depth limit for sport and early technical diving. Inside is the text "SOS Patent" and "Made in Italy".
Operation: The instrument operates entirely mechanically based on water pressure. As the diver descends deeper, the water presses through a diaphragm or tube to advance the needle.
It has a parabolic scale, making readings at shallow depths (where decompression stops are most important) more accurate.
Casing & Strap: The meter sits in a rugged metal housing with a thick glass or plexiglass lens. It has a wide, sturdy black rubber wristband with a metal buckle to withstand the heavy pressure underwater.
Current status: Collectors’ item
Today, divers use modern digital dive computers. This type of analogue instrument is now mainly sought after by collectors of vintage diving gear (scuba memorabilia) or by people diving with historical equipment.
Origin: Italy.
Brand: S.O.S.
Diameter: 65mm.
Thickness: 36mm.
Period: 1968.
Length: 285mm.
