zOwie Omega Discussion Forum

I am fairly new to watch collecting, and am "getting the itch" for a new toy. I have previously concentrated mostly on Baume et Mercier models, but want to get an Omega this time. My first question is where is the best place to buy a "grey market" Omega watch from? I have seen the Omega Seamaster model 2598.80 for $1679.00 on worldwatches.com, but have never bought from them. Does anyone have any experience(s) with them? It is important to me that my watch come with a legit serial number! I don't care about the Omega factory warranty, but do want a visible serial number that hasn't been filed off.

My second question is advice on which Omega would probably suit my needs best. I am torn between the 2598.80 Seamaster and the 3521.30 Speedmaster. Worldwatches.com offers the Speedmaster model for $1,199.00. I like to wear my watch 24 hours a day, whether showering, swimming, biking, at the gym, etc. I prefer a heavy watch, and am concerned that the Speedmaster may be prone to water or steam damage. I also lean toward the Seamaster as it is a certified chronometer, and would most likely tend to be more durable and accurate than the Speedmaster in the long run. However, I like the looks of the Speedmaster best. Any thoughts? I appreciate any info/advice you can give me. Thanks for your input! Jeff
