Automatic quartz is a collective term describing watch movements that combine a self-winding rotor mechanism [1] (as used in automatic mechanical watches) to generate electricity with a piezoelectric quartz crystal as its timing element. Such movements aim to provide the advantages of quartz without the inconvenience and environmental impact of ...
A diving watch, also commonly referred to as a diver's or dive watch, is a watch designed for underwater diving that features, as a minimum, a water resistance greater than 1.1 MPa (11 atm), the equivalent of 100 m (330 ft). The typical diver's watch will have a water resistance of around 200 to 300 m (660 to 980 ft), though modern technology ...
The Spring Drive uses a conventional mainspring [3] and barrel [4] along with automatic and/or stem winding to store energy, just as in a mechanical watch. [3] However, the escapement and balance wheel in mechanical watches is replaced by Seiko's Tri-synchro Regulator system, a phase-locked loop wherein a rotor, which Seiko refers to as a "glide wheel", is powered by the mainspring barrel via ...

In 1968, Seiko introduced three ten beat (ten ticks per second) calibers, the automatic caliber 61GS, the manual winding 45GS [46] and 19GS [47] for women's watch. The 61GS was Japan's first automatic ten beat watch, and it was the most accurate mechanical watch due to the high beat calibers. [ 48 ]
Later specialized tool watch designs were introduced like the Promaster Eco-Drive Professional Diver 1000M Titanium BN7020-09E in 2017. This is a very large watch, the titanium watch case has a diameter of 52.2 mm and thickness of 22 mm and features a helium release valve, designed for mixed gas saturation diving at great depths.

When saturation divers operate at great depths, they live under pressure in a saturation habitat with an atmosphere containing helium or hydrogen.Since helium atoms are the smallest natural gas particles—the atomic radius of a helium atom is 0.49 angstrom and that of a water molecule is about 2.75 angstrom—, they are able to diffuse over about five days into the watch, past the seals which ...
