Dress Watch - IWC Portuguese Chrono-Automatic

Thinking about picking up an IWC Portuguese Chronograph watch (black strap, black dial) to use as a watch for work.

I'm looking for something elegant and subtle (not a big fan of the plain dials so would prefer some chrono). Do you think this will do the trick? If anyone owns one of these, how are they? Do they last over time?

I currently wear an Omega Speedmaster (metal bracelet). Looking for something a bit dressier now. Any suggestions other than the IWC mentioned above? Looking to spend around 6K-8K but can be tempted to go above if the watch is VERY VERY nice. No Rolex though; don't know why but I have never liked them that much.

Thanks for the feedback.

The JLC looks great too. Hmmmmmmmm.......I might need to go have a look at it and try one on to see how it feels.

In terms of the size of the IWC, agree that it is slightly large (diameter) for a dress watch but it's less than 2mm larger than what I wear now and it is slightly thinner too so shouldn't be a problem for me. Ideally, in a perfect world, it would be smaller and my decision would be all that easier.

Thanks for the advice.

Went back and had another look at the IWC and yeah.....it is quite big to be used as a more formal/dressier watch.

After looking in many shops and trying on numerous watches I finally decided on buying a Patek Philippe Calatrava 5196. Much more suitable for a dress watch than my current Omega and the sub-dial seconds gives it something additional as I did not want a very plain dial. However, it did cost a lot more than what I originally budgeted for but at that moment in time I didn't care. Just means I need to cut down on spending in other areas for now........beans on toast it is for dinner! Hopefully this watch will be worth it though and will last for many many years.
