It seems that I have been noticing this brand or rather it has been jumping out at me in the last 1 month. It started with my brother getting his Sinn Watchbuys Limited Edition U1 on rubber strap.
Then at school while picking up my kids, I saw 3 guys with Sinn watches. Between them there were 2 Sinn U1 on rubber strap and 1 Sinn U2 also on rubber strap.
And recently while visiting the doctor, I walked past a watch shop and they had this for sale, The Hour Glass Sinn Tempus on rubber strap.
