From tidal constituents
to the graph on your wrist.
The tide curve of Cuxhaven, built from its constituents. Real TICON-4 data, added up as the watch does it. The same curve becomes the watch face graph.
01 · Live tides
The same calculation.
Here and on your wrist.
This page runs the watch face’s own tide engine: the same station data, the same yearly factors, the same rules for high and low water. Pick an example station and compare it with your watch.

TICON-4 has no chart datum, so heights differ from tide tables. Times are an approximation and not suitable for navigation.
02 · The display
One glance.
The whole tide.
- Three slots along the edgeSun arc with sunrise and sunset, tide element, moon phase or a data field. Every slot is your choice.
- Info lineNext high or low water as a time or a countdown, optionally with station name and height.
- Tide graphCalendar day from 00 to 24 or rolling: 6 hours back, 16 hours ahead. Spring tides fill the graph, neap tides run flatter.
- Now markerShows the current level on the curve. On the calendar day it moves; rolling, it stays put and the curve flows through.
- Time axisHours, the times of high and low water, or ticks only.
- Time and statusLarge time with date. Seconds, Bluetooth and notifications on request.
03 · Features
Precise beneath the surface.
Harmonic Tide is a tide calculator inside a watch face. Everything you set up happens in Garmin Connect or Connect IQ.
Harmonic prediction
The tide is built from the station’s constituents, 23 per station on average, with yearly factors up to 2056. High and low waters are refined to the minute.
Three ways to a station
Automatically the station nearest the watch, a station number from the station list, or the station nearest to coordinates you enter. Inland, the last station stays.
Local correction
If your harbour lies further up an estuary, enter one high water and the following low water from your tide table. The watch shifts the station’s times to match.
Sun and moon
Sun arc with sunrise and sunset, even when the sun only sets after midnight. Moon phase in 32 steps from the sun-moon elongation.
Your graph, your axis
Calendar day or rolling, an axis with hours or tide times, an info line with countdown or clock time. Optional smooth gradients on colour MIP.
Always-on for AMOLED
Time, date, tide line and status icons, or time and date only. A pixel grid protects the display from burn-in.

Three display worlds.
Each display type gets its own drawing: fine gradients on AMOLED, strong colours on MIP and a dedicated 1-bit view for the Instinct.
Original simulator captures with the watch set to German. The watch face speaks English and German. On the Instinct and on models with 96 KiB of memory the local correction is left out, on the 96 KiB models also the upper tide element. The main graph is always there.
