I bought this watch for my boyfriend.  He loves how it looks and received compliments on it the first day he had it on.  But we noticed that the watch doesn't keep time as long as other mechanical hand winds.  I have an Invicta mechanical hand wind and it lasts for 24+ hours.  The Akribos Davinci stops after a couple of hours and needs winding to start again.

I really wanted to return it to Amazon, but he just loves how it looks so much that he decided to keep it, and is instead winding it throughout the day so that it doesn't stop.  I signed up for the Akribos warranty just in case if it completely fails to turn on.

Edit: The watch is not accurate.  By the end of the day, it's one hour ahead of the correct time.  He decided to still keep it though purely because it looks good.
