I needed a tool to change the way my watchbands. It works well with all pumps of my watches but it is very very small, bracelet changes can then be made with 2 or 3 fingers, which greatly complicates the. The pin hunting function to shorten the bracelets works but the tip is very fragile, it broke gently after the 2nd use, it does not matter to me because I do not use it but sachez- if you buy this product for it. I suspected as much for a product to 0.16 but the product did the trick and I always use.
PS: 1 to 0.16 with shipping costs, order several, to avoid relying only one of these little fragile tools, the exchange port price not depending on the quantity.
