When I first joinned the forum in 2009, these were a real forum favourite, but you rarely see them mentioned now.
Love them, but for me the one to have is the vintage model from back in the days when it was the tool for the job. The size is a bit of a red herring in that the bulk of it runs comfortably up the forearm.
If anyone fancies one but finds the modern one a little expensive and/or blingy, have a look at a vintage one. I'll never sell mine. It's something truely unique in a world os 'samey' watches.
