Seamaster Aqua Terra 150M — Winder Setting Overview
If you own a Omega Seamaster Aqua Terra 150M (reference 220.10.41.21.03.004), the TPD figure below tells your watch winder exactly how to look after it. The Seamaster Aqua Terra 150M runs on the Cal. 8900 calibre. Here's everything you need to programme your winder correctly.
TPD and Winding Direction
Programme your winder to 725 turns per day and select bidirectional rotation. These are the exact figures the Seamaster Aqua Terra 150M is designed to wind at.
Why the Correct Setting Matters
Think of the right setting as cruise control for your power reserve. It keeps the mainspring at full charge so the Seamaster Aqua Terra 150M holds accurate time and never stops between wears, saving you the daily reset ritual.
Worth knowing: an incorrect TPD won't damage a modern automatic movement, because the slipping mainspring simply can't be overwound. Getting the figure right is about keeping the watch accurate and ready, not about protecting it.
Choosing a Watch Winder for the Seamaster Aqua Terra 150M
The key spec is programmability: your winder must let you dial in 725 turns per day winding in both directions. Single winders suit a one-watch collection; multi-watch winders suit a rotation. Explore our watch winder collection and pick a unit with individual TPD and direction controls.
Seamaster Aqua Terra 150M Winder FAQs
How many turns per day does the Seamaster Aqua Terra 150M need?
Use 725 turns per day — that's the winding rate specified for the Seamaster Aqua Terra 150M, and it keeps the power reserve topped up around the clock.
What winding direction does the Seamaster Aqua Terra 150M need?
Bidirectional rotation is correct for the Seamaster Aqua Terra 150M. Avoid clockwise-only or anticlockwise-only programmes, which would only do half the job.
Will any automatic watch winder work?
Any programmable automatic watch winder with a 725 TPD bidirectional programme will work. Steer clear of fixed-cycle winders that can't be set to the right figures.
