This easy adjustable stainless steel deployment buckle will work with most leather bands. It will add a nice look to the leather and extend its life. Putting on and taking off your band will be easy and quick. In general most bands are tapered about 2 mm at the buckle attachment from the watch case attachment. For example if your band is 20mm most likely you will have an 18mm deployment buckle. There are exceptions, some bands are tapered more and some are not tapered at all. It is best if you measure the width of the band where it is attached to the buckle.
