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.

Though it is an improvement in my situation. The clasp could stand to have a couple of additional micro-adjustment holes for a total of 5 or 6. Also, being for the Seiko bracelet specifically, the actual latching mechanism does not latch to the Seiko post/stud as well as the original clasp does.
