I bought 2 versions of the 21mm strap:
Brown: it is ideal for my Orient bambino V2 with cream face and blue hands. it is vibrant brown, not too dark and not orange, it has a matte finish and there is a lot of depth in the color.
Black: ideal for my OB V3 with gray dial, it manages to look stron, bulky and at the same time refined, it has bright matte finish.
both straps are soft and do not need to be broken down, they also look more expensive and high quality than a lot that you may find in this sight for the same price.these are so good, that i finally decided to settle with these, it has been hard to find straps for my bambinos,  i was doubtful of these because of the price, seemed to good to be truth, but after i saw them and felt them in person, i regret not purchasing them any sooner.
