I love this watch! Just wear it and forget, never thinking about having to charge it. One thing that i miss is a vibrating motor for the alarm. I know other models have that, but i miss it on this one.
Yes it's a 22 mm nato. Much better then the original strap. Jays and Kays strapadapters, after I bought these I discovered that they also have adapters for 20 mm, so can can use the straps with more watches. Instead of starting at "12" I started at "6" to mount the strap, looks better
I am about to buy a gwm 5610u, jays and kays 22mm, and thinking of nato and perlon straps from either crowns and buckles or CNS, but I hear crowns and buckles is better so I might shell out for the extra cost.
