The Duetempi Wall Clock is probably best suited to those people who care a little bit about what the time of day might be, but who aren't overly scrupulous. Of course, this eccentric chronograph will accurately track and express the hour; however, the difficulty is reading it correctly.
The reasons why this is so difficult are multiple. Firstly, even if you install the square timepiece straight, the markings on the face of it are scattered about inconsistently. You're better off ignoring the indicating ticks and simply noting the positions of the hour, minute and second hands. This is an even more necessary technique for unscrambling the time when Alessandro di Prisco's Duetempi Wall Clock is hung up with a tilt.
