@PolarChess -
I own the BHB analog clock (wood case) and also the INSA analog clock. Both work well. The BHB can hardly be beat for a truly (mechanical, wind-up) analog clock. It takes a licking, and keeps on ticking. However, if you are kind to your clock, and don't beat the H*LL out of it, I suspect any of the mechanical clocks here would serve well for casual play....
