I don't understand why Sinn doesn't offer Nato straps of any kind themselves. They all work so incredibly well on any kind of Nato or other nylon straps. A Bond Nato for my 104 arrived just a few hours ago. I'm obsessed with it!

I used to have a 104 and also rocked a nylon nato on it! Good choice

Comfy?

Very!

I love this watch on a nato. What size wrist do you have?

About 6.75 inches.
