※ We offer a discount of 300 yen off for each additional item purchased when you buy multiple watch straps, etc. that we are selling. This is not a genuine product, but it is a D-buckle of the same type as the Patek Philippe Nautilus. Since there is no logo, it can be used on watches other than Patek. It has a polished finish. It fits straps with a buckle width of 18mm, not the lug width.
