After all the great comparison pictures yesterday from Tim I thought I would give it a try.
The three watches pictured are the Sinn 103 Ti UTC, Sinn U1 and the Damasko DA36.
I love the color and light weight of the Titanium on the 103 but it's ability to be scratched makes is a real disappointment. I have loved the Sinn Sub Steel since I bought my U1. It has seen a ton of wear but still looks brand new. The sub steel has a darker than normal steel look and tends to have a pearlescent color to it. The Damasko steel in my opinion is the best of both worlds. It is darker than the sub steel and the ice hardened steel is stronger than the sub steel. I have been very impressed with the Damasko to say the least.
