A Omega Seamaster Aqua Terra 150M GMT Worldtimer that sits unworn will run its power reserve down within days. Set a winder to 650 turns per day, rotating in both directions, and it stays wound without any fuss.

Why These Settings Matter
Programmed correctly, a winder mimics a day on the wrist. For this movement that means 650 turns spread across the day on a bidirectional cycle, which keeps the Seamaster Aqua Terra 150M GMT Worldtimer ready to pick up and wear with the correct time and date showing.
And if the figure is set too high? Modern automatic calibres protect themselves: the mainspring bridle slips inside the barrel once full wind is reached, so surplus turns are simply shed. The watch cannot be overwound or damaged by a winder — a low setting that lets it stop is the only outcome worth avoiding.
Because all Aevitas winders offer settings from 650 to 1,850 TPD, you can programme exactly 650 TPD for this watch — and reprogramme in moments if you swap watches around.
