Ok, great, thanks!
But, as I don't have any experience with movement swap, what's with the dimensions? I mean, all those suggested movements are, as I can see, aprox 26m in diametar, and the 21J that is presently inside is about 34. My question is, how would the 26mm movement fit 42mm case watch? My main concerne is date window... Maybe my question is stupid one, but it's the first time that I am trying to change the movement to one of my watches, so please be kind on me
