I always heard mine too but unless I'm wanting to hear it differently I can hear the rotor spinning much louder than I remember it last a month ago. It just sounds like the rotor is a little loose. The power reserve of it is not close to 44 hours as I've seen online though. It's closer to the 30 hours mark. I'll wear it again and measure its accuracy and power reserve with WatchCheck.
On the other hand, I jus bought a SRP313K2. Always wanted an Seiko Orange Monster but their prices are much higher than I'm willing spend so I settled for the Seiko Dracula.
