Before we have discussed 5 features of a divers watch and now we will continue with some more features.

Pushers

Digital and some analog chronograph scuba diving watch - such as the Breitling Avenger Seawolf Chronograph, Doxa T-Graph, IWC Aquatimer Minute Memory, the Omega Seamaster Professional Chrono Diver series and Sinn U1000 - have specially-designed push pieces that can be operated at depth without allowing water to enter the case.

Helium release valve

Some scuba diving watches intended for saturation diving at great depths (typically greater than 100m) are fitted with a helium or mixed breathing gas release or escape valve to prevent the crystal from being blown off by a pressure build up caused by helium that has seeped into the watch in helium enriched environments as the watch and diver adjust to normal atmospheric conditions. Other helium safe/for mixed-gas rated diving watches can withstand the helium used in certain diving situations by using gaskets that simply do not allow helium gas to enter the watch case in a harmful way in the first place.

Legibility

The dials and markers on the scuba diving watch face and of course the bezel have to be legible under water and in low light conditions. An indication that the watch is running in total darkness also has to be present. For easy legibility most diving watches have high contrasting, none cluttered dials and markers with a large, easily identifiable minute hand. The markers for 3, 6, 9 and 12 o'clock on the scuba diving watch face and the zero marker on the bezel of analogue diver's watches are usually conspicuously styled to prevent disorientation induced read out errors. For low light conditions luminous phosphorescent non-toxic strontium aluminate based lume pigments marketed under brand names like Super-LumiNova or NoctiLumina and tritium based self-powered lighting devices called "gaseous tritium light source" (GTLS) is applied on the dials and markers. As for digital diving watches back lights are used for low light conditions legibility.

Power reserve indicator

A scuba diving watch with an electric battery powered movement must have an End Of Life (EOL) indicator, usually in the form of a jumping second hand or a warning message on a digital display to safeguard against insufficient power reserve during underwater activities. Some electric and mechanical powered movement diving models have power reserve indicators that show the current power status of the watch. Mechanical movements should be wound or in case of automatic movements given enough motion before a dive.

Crystal

Scuba Diving watches have relatively thick watch crystals face. Sometimes domed crystals are used to enhance the pressure resistance of the scuba diving watch. The typical materials used for crystals are acrylic glass, hardened glass and (synthetic) sapphire which all come with own pros and cons.

* Acrylic glass is very break resistant but can easily be scratched but the small scratches can be buffed out with polishing compounds.

* Hardened glass is more scratch resistant than acrylic glass and less brittle than sapphire.

* Sapphire is very scratch resistant but less shatter proof than the other crystal options. Anti-reflective coatings are generally applied on sapphire crystals to enhance the legibility of the watch.

Some manufacturers use sapphire/hardened glass laminate crystals, where the scratch resistance sapphire is combined with the better shatter resistance of hardened glass.

The TBF Avenger manufactured by Grumman was a torpedo bomber. It was used by a large number of air forces around the world initially developed for the United States Navy and Marine Corps. It entered service in 1942 and first saw action during the Battle of Midway. The Grumman TBF Avenger had a large bomb bay allowing for one BlissLeavitt Mark 13 torpedo a single 2000 lb (900 kg) bomb or up to four 500 lb (230 kg) bombs. Torpedoes were generally abandoned after Midway and were not carried again regularly until after June of 1944 when improvements mandated their use again. By that time it was rare for American aircraft to encounter enemy shipping at sea and the Avenger was primarily employed as a ground support weapon. The plane had overall ruggedness and stability and pilots say it flew like a truck
