At one time I doubted whether a buckle, different from stainless steel or silver, would fit in a stainless steel case. Doubts can be understood, because the first thing that comes to mind: bronze to bronze, black to black, stainless to stainless steel.
However, over time, I tried different combinations, I came to the conclusion that it is more important to buckle the buckle with a strap than with the body of the watch itself. In support of my words buckles of brass, bronze and meli on the clock in a stainless steel, tell me, does not fit? ;)
