Seiko Replacement Clasp Covers

Can confirm this clasp cover fits the newest Seiko Alpinist references (SPB505) PERFECTLY. Ive seen it can be tricky to install on some previous references with a slightly different design but now it is as simple as removing two spring bars and fitting the new clasp cover. The steel color difference between the dia-shield coated bracelet and the new clasp is not as noticeable as I was worried it would be and the finishing is on par with the original clasp. My wrist can finally breathe!

Good replacement clasp for the SPB155 Baby Alpinist stock bracelet. The extra microadjust really helps with sizing. As noted in other reviews, installing it on the SPB155 is easy enough but requires an extra step to make it work without breaking the extra fine spring bar.

Feels like a low-quality product. When you move your wrist, this clasp makes a sound like a musical instrument. Installed on a bracelet or itself, this lock mechanism has a lot of extra space between parts so they do hit each other. The stock Seiko clasp is much better. This product is not worth $15, including the $15 shipping cost. Delivery to Ukraine takes ~20 days instead of 14. Such a waste of money and time.
