This one probably is a bit to far off the path for some, but not for me. My first "good" watch that I purchased was a beautiful Longines that had, among other things, a retrograde seconds hand. I liked the watch, and loved the retrograde seconds, but it was too thick to fit comfortably under a shirt cuff, so I sold it. Ever since, I've wanted another retrograde seconds watch, but there are very few out there, and many are hideously expensive.
Then, in the 2015 watch catalog I got at the holidays, I saw this newly-introduced watch from Schaumburg in Germany, and now, it has arrived, in a beautiful, leather-covered wooden box:
Inside, the Schaumburg Retrolateur 2:
I've not seen another watch like it, combining not one but two retrograde second hands, plus a regulator format, splitting out a small dial for the hours (with contrasting white Roman numerals), and a large minute hand. The bottom second hand goes from 0-30 seconds, after which it snaps back to 0, and the top second hand starts its journey from 30 to 60, after which it snaps back to 30 and the 0-30 hand starts again. It's pretty cool to watch.
On these pictures, you can see there are four different guilloché patterns on the dial, one for the minute track, one for the main part of the dial, one for the two second hands, and another for the inside of the hour subdial. The watch dimensions are reasonable, 42mm x 12mm, with reasonably short lugs.
The main parts of the case are brushed, with the bezel and the case back bezel polished. I think the signed onion crown works well, too.
The movement is a pretty heavily modified Unitas 6498, hand wound, 18000 vph. The finish? Oh, wait for the next post below...
