GMT II Losing Time?

[SC197]

Hi everyone, running into a "minor" issue here...

I got the new GMT II about 5 months ago, and for 3-4 months it was extremely accurate. I was essentially wearing it daily, months would go by and I would be off within a minute to actual.

However, lately I've been noticing that my watch has been losing about 5 seconds daily. I've tried everything (manually winding it more frequent, setting it down in different positions) and nothing seems to work. I personally hate it when my watches are slow (rather it be quick than slow). Just wondering if anyone has had the same experience?

Also, would this be something worth sending it into RSC or should I wait until much later? I want to say I really dont use my watch to tell time and its really there as an accessory, but something about knowing it not keeping accurate time still bugs me.
