Water Resistant vs. Waterproof. No watch is completely waterproof. Most mechanical watches have water-resistance ratings that prescribe a maximum immersion depth. This depth is measured in feet, meters or atmospheres (ATM), where one ATM is approximately 33 feet or 10 meters.
In 1978, Seiko introduced twin quartz watches, with two crystals, which offered accuracy within five seconds per year, and quartz divers' watches with 600-meter-depth water resistance, followed in 1979 by the ultra-thin quartz watch with 0.9 millimeter movement, along with the analog alarm quartz watch.
