Hi,
Accidentally I have found and bought a very interesting timepiece: Casio FT-100W "Fish En Time" - module 844, the first watch dedicated to the fishing amateurs (1989).
It may be seen in the below photo, next to my new/NOS Casio SPF 10 - Radiant Thermo Scanner watch (2002 - module 2030) - which I consider it to be the current ULTIMATE Fishing Watch - but being oriented more to the marine/professional fishermen ( and hopefully NOT the last one in this field, since Casio has even now some less advanced watches in their current Fishing/Hunting Gear line).
Thus because the Casio SPF(SeaPathFinder) 10 may be programed - using GPS coordinates and accurate lunitidal intervals - to compute moon phases and correct tides using proper lunitidal intervals simultaneously for up to 10 different fishing sites around the World + to SCAN using the integrated ThermoScanner the average water temperature - all these kind of data being considered important for the marine/professional fishing field:
But, why is the old Casio FT-100W also interesting?
I. Under my current knowledge, it is the last model of "pure LCD" Casio watches that have the famous "Marlin" brand on it - produced in 1989 - (even if some Casio "purists" do not consider it a true "Marlin" watch, being labeled FT, not W/DW) and together with the logo "Fish EN Time", - not "in time" as it is correct (pls see the above photo).

II. It is also, the first watch that may calculate the proper Fishing Time by the Celestial Angle-Hour method - with the Celestial Hour Angle results displayed in a somehow similar (but not identical) manner as in the already famous Casio GMW-15 Moon Graph (module 832) watch from 1980.
What is Celestial Angle-Hour?
Basically, if we consider the observer's Meridian as the ""point zero", the Moon's rotation angle from that meridian on the East-West direction is called Hour Angle (H.A.), as You may see it in the picture below, from the https://www.astro.umn.edu/courses/1001/ ... ience.html:
How Celestial Angle-Hour method works for a fisherman?
It is quite simple :"Every fisherman knows that the best fishing times are when the fish are feeding. This tends to be during dawn and dusk, but what often goes unnoticed are the two periods elsewhere in the day--moonrise and moonset. Because the moon has an effect on a variety of factors surrounding the fish--including the live fodder they hunt--these periods, combined with the moon's phase, are what trigger feeding. By understanding this, and choosing times when sunrise/sunset and moonrise/moonset coincide with new or full moon phases, you'll increase you chance of a good fishing catch.
There really is nothing complicated about this at all; it's just a matter of knowing ahead of time exactly when the sun and moon will rise and set. Fish are most active during 90-minute windows surrounding each of these four daily events; that's 45 minutes before and after these four daily points. ".

For all the above mentioned fishing reasons, the watch will compute and display (see the photo below):
- Moon Phase;
- Moon Age;
- sunrise/sunset;
- moonrise/moonset (via an interesting Celestial Angle-Hour display with bars - often confounded by some Casio users with the Tide Bars from other Casios!!!)
for every place in the World (by entering proper Latitude/GMT+- difference data instead of Longitude) and every specific day/date from 1985 to 2029!
- fishing marks ... for those who are lazy enough to not challenge their minds with some "complicated" computational tasks regarding the proper fishing time , there are some fish "floating" on the screen (so-called fish marks from 1=bad fishing time, up to 4=excellent fishing time) displayed at the four Celestial Hour-Angle points/bars of about 0, 6, 12, 18 hours of that day....pls see the photo below :)
If You want more information about this kind of Casio's particular (fishing) watches, please let me know.

Every watch should have its own story...consequently, a watch collector has to be a good storyteller :)
