Seamaster 300m Not holding Charge?

I have Seamaster 300m
Purchased August 2021

Even after wearing for a whole week and fully charging the watch it loses the charge with 36 hours. Is this acceptable?

I also have a (much cheaper) Seiko Kinetic and this holds a full charge for weeks after being fully charged.

Does anyone feel this is a problem?
Should I return the watch to Omega for them to check it out?

Thanks in advance for any help
