Thank you for viewing! This is a D-buckle (butterfly clasp type) from CASSIS, a specialty store for watch straps. I purchased it but didn't have a chance to use it, so I'm selling it as a new, unused item with tags. It can be attached without widening the holes in the leather strap, which significantly extends the life of the strap. Also, it makes it very easy to put on and take off your watch with a single push. It's a 10mm size, making it ideal for ladies' watches or straps where the buckle side is narrow. 【Product Details】 ● Brand: CASSIS ● Product Name: PBF D-BUCKLE ● Model Number: CASSM 010 ● Size (Buckle Width): 10mm * Please check the strap width at the point where the buckle attaches, not the lug width of the watch itself. ● Color: Mirror Silver (mirror finish) ● Material: Stainless Steel (316L) ● Type: Butterfly clasp (push type) ● Retail Price: 4,400 yen (tax included) 【Condition】 ● New, unused ● With tags ● Some protective film may have been peeled off for photography and inspection, but it has not been used. 【Shipping】 I will wrap it in cushioning material (bubble wrap), take measures to prevent water damage, and ship it via anonymous delivery. Immediate purchase is OK. Please check the buckle width of your watch strap carefully before considering purchasing. #CASSIS #Cassis #D-buckle #ButterflyClasp #WatchParts #10mm #Silver #WatchStrap #Buckle #LadiesWatch #ReplacementStrap
