An analog marine chronometer with the tide under your hands. Free with all features, no ads. Development and the weather server run on tips — thank you: https://boosty.to/tide4a Website: https://tide4a.com Tide 4a Analog puts the Tide 4a engine on an analog dial: railway minute track, a 12-hour forecast ring where the hour hand points at the current hour's weather, a wind bezel colored by strength, and the tide curve in the centre. Offline tide prediction, worldwide — harmonic constants of the nearest tide gauge (2,400+ stations) computed on the watch; works for weeks with no phone once synced. Verified against published tide tables to within minutes. 12-hour forecast ring: each cell sits where the hour hand will be at that hour and shows wind speed with a direction chevron, the weather icon and temperature; the bezel arc behind it is colored by wind strength (up to 5 / 6–10 / over 10 m/s). Sea water temperature at your spot (model surface temperature, Open-Meteo Marine) on the right flank. Tide block: curve −6…+10 h, countdown to the next high/low water with the height delta, the next two events with times and heights (m or ft). Sun on the tide graph: an amber daylight edge with sunrise/sunset ticks under the tide by default; or darken the water for the night hours, dotted sunrise/sunset marks, or water and edge together. Pressure with its 3-hour trend in the battery row. Moon phase, sunrise/sunset, heart rate, steps, battery in days (solar intensity in the barometer view on MIP solar models). Barometer with storm alert when far from the sea. Four hand styles (sword, dauphine, sabre, arrow), optional seconds hand. AMOLED: metal hands, glow, always-on display with burn-in protection. Font size: standard / large / maxi (large by default). °C/°F, m/ft, m/s or knots, mmHg/hPa. English, Russian, French, Spanish, German, Portuguese, Dutch, Turkish, Japanese. Requires a phone paired with the Garmin Connect app for weather and tide updates; once synced, tide prediction keeps working with no phone. Tide predictions are for general information only — not for navigation or dive planning. Tide constants: TICON-4 (DGFI-TUM, CC-BY-4.0, https://www.seanoe.org/data/00980/109129/). Weather: MET Norway (api.met.no, NLOD/CC-BY-4.0) and Open-Meteo. Location coordinates are sent only to the developer's proxy to fetch weather and tide data; nothing is stored.

Readability: the "maxi" font size is now bolder, and a new "maxi+" level makes the key figures bigger - temperatures in the forecast ring, sunrise and sunset, the date and the tide countdown. The wind figures leave the ring (the arc colour shows the strength). Font size is in the watch face settings.
