·Hello. I bought my first Omega watch. Aqua Terra with coaxial mechanism 8900. I started it manually with 50-60 turns and started wearing it day and night without taking it off my hand. After two days it stops and I have to start it again manually by turning the crown. It behaves as if the self winding part does not exist. Is this normal or is this how this mechanism behaves? Thank you.
