The Cousu Main (hand sewn) inscription appears in Camille Fournet (CF) straps. I don't know if other manufacturers use that inscription too. I have only good experiences with CF straps. Excellent quality and duration. Regards, Daniel
I am of the same opinion as Dje. If you can stand that your watch is not perfect for some time, wait until the next service to send it to JLC. They will polish the watch anyway with each service, and therefore you will have no extra cost. Regards.
