The range of functions included world time for 24 global cities; regatta countdowns over five, three and one-minute durations; depth gauge; electronic compass with magnetic declination compensation; [6] perpetual calendar; altimeter; tide; temperature and flyback chronograph (with the ability to stop the chronograph at each lap to note the lap ...
The Timex Expedition WS4 is a multifunction digital watch produced by Timex. In addition to regular timekeeping, it features barometer, altimeter, thermometer, compass, and weather forecast functions. "WS4" stands for "Wide Screen 4 Functions". [1] [2] It was introduced in May 2009. [3]
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
Timex Datalink or Timex Data Link is a line of early smartwatches manufactured by Timex and is considered a wristwatch computer. [1] It is the first watch capable of downloading information wirelessly from a computer. [2] [3] As the name implies, datalink watches are capable of data transfer through linking with a computer.

High and low tide in the Bay of Fundy. The theory of tides is the application of continuum mechanics to interpret and predict the tidal deformations of planetary and satellite bodies and their atmospheres and oceans (especially Earth's oceans) under the gravitational loading of another astronomical body or bodies (especially the Moon and Sun).
Tide range is the vertical distance between the highest high tide and lowest low tide. The size of the lunar tide compared to the solar tide (which comes once every 12 hours) is generally about 2 to 1, but the actual proportion along any particular shore depends on the location, orientation, and shape of the local bay or estuary.
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
A tide gauge The tide gauge in Kronstadt, Russia [1] A tide gauge is a device for measuring the change in sea level relative to a vertical datum. [2] [3] It is also known as a mareograph, [4] marigraph, [5] and sea-level recorder. [6] When applied to freshwater continental water bodies, the instrument may also be called a limnimeter. [7] [8]
