First Rolex Sub/ExpII Dubai/Singapore

[ROLEXUS]

Hi all,

Looking at buying my first Rolex. Will probably be the only one I ever buy as i'm not really a collector or enthusiast but just want to have a nice watch which I can keep with me for many years to come. Have basically narrowed my selection down to either a Sub date or an Explorer II which seem to be the most suitable watches for a first (and only) time buyer. Both watches offer a blend of sportiness and elegance and are appropriate for all occasions. I know in the end it comes down to personal choice but overall which one would you guys recommend out of these models in terms of comfort and durability (resistance to scratches). Also are there any major differences between the two (apart from looks) which I should take into account when making the decision??
I'll be travelling to Europe in the next week stopping in Singapore and Dubai which is where i'll be looking at buying (from an AD of course). Does anyone know the current rrp for both models in these cities and how much of a discount I could expect with some serious haggling??
Also what's the go with the Rolex SS bracelets?? I'm guessing they're hollow links as they feel very flimsy when compared to the solid feel of an Omega??

Thanks
