If you do go vintage, how about a 166.073. These also came on a bracelet but look good on a mesh as well. Here's mine but it is not all original having a newer dial and hands. A top one of these with bracelet should be easily within your price range.

A sweep seconds is, strictly, a complication by the way. I know you said no other complications but, if you like a big watch, how about a Yachting? $4k might be ambitious for one of these in very good condition though. Hard to resist, in my opinion
- I couldn't!
