Is this normal?

I know it's an Omega forum, but I gave. Davosa Ternos and when it's coming to the end of it’s power reserve it loses time. Say the last few hours, it loses about twenty seconds. Fine when it's on the wrist though, but never get fully wound.

Absolutely normal. You can fully wound it manually before using .
