Sinn U1 SDR With extra strap ETA 2824

[rambo4hire]

I have a Sinn U1 SDR. This model is one that has the ETA movement not the Selita movement. Comes with box manuals and cards. The original rubber strap is sized for a wrist smaller that 7.25. The one on the strap fits my 7.25 size wrist. Asking $old
