Same as others have said. My Coaxial movement Seamaster with the 2500B movement can be hand wound in the first crown position and runs slightly off spec at - 5 secs per 24 hours. This is after eight years of ownership, several activity holidays and wear in rotation with other watches in my collection. Power reserve after a normal days activity is around 30 hours. If yours has been in the AD for a while it may take time to settle to your wearing pattern. An old watchmaker once advised me to wear any watch new or just serviced for two weeks on a daily basis. This was before modern movements but still sound advice in my opinion.
