I am looking at two similar watches from Seiko, the SKX009J and the SNZF15J1 Seiko 5. I am seeing some inconsistent listings of the specs, however. Is the SKX 42mm with 22mm lug width and the SNZF 40.5m with a 20mm lug with? The reason it matters is that I already have a watch with a 20mm lug width and I want to know if I buy extra straps that I can put them on either watch, so that would be the tie breaker in my decision. Any response is appreciated.
