Omega Seamaster Aqua Terra Worldtimer TPD | Aevitas

If you own a Omega Seamaster Aqua Terra Worldtimer (220.10.43.22.03.002, Calibre 8938), here are the correct watch winder settings to keep it running accurately without overwinding.

Note: the Calibre 8938 is a relatively new or uncommon calibre with limited published winder data. The 650 TPD bidirectional setting below follows the manufacturer's calibre family baseline — check your watch's documentation if unsure.

Why These Settings Matter

Setting your winder to 650 TPD bidirectional matches the Calibre 8938's power reserve characteristics. Too many turns per day won't damage a modern automatic (the mainspring slips), but it causes unnecessary wear. Too few and your Seamaster Aqua Terra Worldtimer will run down and stop, losing time and date.

All Aevitas winders offer programmable TPD settings from 650 to 1,850, so you can dial in exactly 650 for your Seamaster Aqua Terra Worldtimer.
