For many years clocks have existed with a hand supposed to show
the state of the tide. These suffer from two considerable defects.
They can only be set up for one location and resetting for another
place is complicated and laborious and secondly they are only
accurate twice in a Lunar cycle During the rest of the fortnight
these simple time pieces, based on Lunar time, will be up to an hour
and a half wrong which can be downright dangerous if, as a result
you strand on a sand bank in deteriorating weather.
Having invented the first tidal monitoring watch three decades
ago the concern was, and remains to provide a measure of tidal
activity that is accurate and flexible, bearing in mind that the
daily increment between tides at Spring and Neaps can more than
quadruple.
Also if making any sort of passage the tide times at one's point
of arrival will invariably be quite different from one's point of
departure.
To accomodate these essential features the unique registered
design Tidal Monitoring bezel needs to be set daily and reset whilst
on passage from local radio broadcasts or readily available tide
tables for the actual locality of operation or from the newer
computer programmes now produced or, as is traditional, calculated
from an Almanac.
However the Moon's phase in conjunction with the Sun determines
Spring and Neap tides. Tidemaster Moonphase, besides elegantly
showing the exact state of the moon incorporates an unique tidal
range scale that shows on the hyperbolic curve whether one is on
Springs or Neaps or coming out of or going into one or another
phase. Together with a particularly clear Tideal monitoring bezel©
very complete tidal information is given at a glance.
© Tide bezels constantly monitor the tidal state and show the
time to High and Low water, the Tidal flow and Tidal height based on
the twelfths scale.
