Minute repeater remains on my wish list and there are very few relatively affordable models for such complication and the Reverso is one of them (with the Portuguese for instance), hence it is on my wish list, even though I have never heard it. I love the understated aspect of such complication, if you don't spot the lever on the side (which could only be spotted by trained "connoisseurs'" eyes), one would just think you have a gold watch and that's it !
Do you have a picture of the movement, is it round ?
