Sinn 556i on steel bracelet.
I've worn this watch regularly and have done my best to take pictures to show the wear.
Let me know if you want additional pictures from different angles.
The strap changing side of the Sinn tool is broken, see pictures for details.
If you do a Google search, you will find that this tool is not well made and it is common for it to break.
I use a Bergeon tool to change straps.
Also included is a cheap brown leather strap that I purchased from EBay.
One of the springbars has come apart as shown in the pictures.
My wrist is around 6.5".
I set this watch yesterday and then used WatchCheck (Android app) to check the time and it is running +5.4 seconds.
I'll continue to check the accuracy of this watch as long as this ad stays up.
This watch has not been serviced.
Asking $950 shipped to the US.
