a little surprised at the thickness of the clock: 4.5 cm, I did not think to check this, not very serious in my case but the big advantage is that this clock can adjust manually, and then run as a conventional clock if one day the satellite signal can no longer, or if the hologe no longer emits, and SCOUR classic case of failure this type of product the product looks well finished, the display is clear, fast delivery and good product packs
