Seamaster Aqua Terra 150m GMT Worldtimer TPD & Winder Settings | Swiss Watch Store
Seamaster Aqua Terra 150m GMT Worldtimer — Winder Setting Overview
The Omega Seamaster Aqua Terra 150m GMT Worldtimer is an automatic watch, which means it winds itself from the motion of your wrist — but on the days it sits unworn, a watch winder keeps the mainspring topped up. Its self-winding movement relies on the rotor to keep the mainspring charged. Below you'll find the exact TPD setting and winding direction the Seamaster Aqua Terra 150m GMT Worldtimer needs.
TPD and Winding Direction
The correct setting for the Seamaster Aqua Terra 150m GMT Worldtimer is 650 turns per day, bidirectional: 650 turns per day with the rotor turning in both directions.
Why the Correct Setting Matters
Accuracy starts with a fully wound mainspring. The correct TPD keeps your Seamaster Aqua Terra 150m GMT Worldtimer's power reserve topped up around the clock, so the movement delivers its best rate and the watch is always ready to wear.
Don't worry if you're unsure — you can't break a modern automatic with the wrong winder setting; the slipping bridle on the mainspring makes overwinding impossible. The right setting just keeps everything running at its best.
Choosing a Watch Winder for the Seamaster Aqua Terra 150m GMT Worldtimer
Pair the Seamaster Aqua Terra 150m GMT Worldtimer with a quality programmable winder set to its 650 TPD / bidirectional programme. A single-watch winder is ideal if this is your only automatic; if you rotate several watches, a multi-watch winder is the smarter buy.
