The C02x movement uses three SR920W (Maxell) or 370 (Eveready) silver oxide batteries. Depending on frequency of use of the depth gauge and alarms, the batteries should last 2-3 years.narwalos said:what is the type of battery inside (there is 3 battery inside) ?
Hi, Sir Les.Sir said:The C02x movement uses three SR920W (Maxell) or 370 (Eveready) silver oxide batteries. Depending on frequency of use of the depth gauge and alarms, the batteries should last 2-3 years.
Btw, I don't think the 'black' model has a titanium case. I think it's the normal stainless steel case, sprayed with a hot mixture of alumina (Al[sub]2[/sub]O[sub]3[/sub]) and titanium oxide (TiO[sub]2[/sub]) to increase hardness and wear resistance. The process is known as 'black spraying' and has been used on the Space Shuttle, jet engines and nuclear power stations.

No, it's a completely different calibre, using 1 large coin-size lithium battery instead of 3 silver oxide cells. The C520 measures depth in metres, and the C526 measures in feet.narwalos said:thank you for your answers.....for the second generation (series) at promaster aqualand there is inside the same movment quartz ??
