QGHXO Band for Polar M400/M430, Soft Adjustable Silicone Replacement Wrist Watch Band for Polar M400/M430 Watch

After almost 6 years, my M400 band broke. I ordered this as a replacement. Good price and quick delivery. Fits perfectly and was pretty easy to put on. I used the tool to push out the old pins and a needle nose pliers to gently push the new pin in. It took some wiggling. Once I got the new pin about half way, I had some trouble getting it through the rest of the way. So, I pushed the tool in from the other side to help line it up. Seems to be a thinner band than the original, but robust enough.

I like this because it is truly Original.

Much better quality than I expected! Super easy install, less than five minutes. Suggest a small tack hammer to lightly tap the two pegs into place. Repeat: lightly. Solid construction, durable material; seems better than the original Polar band. Large strap with multiple sizing options and includes double loops to hold strap in place, and three piece easy to use install kit. Super snug, super comfortable fit! I tried finding replacement bands on Polar.com to no avail. Excellent value!

The band fit the watch well and installation was easy. The band is much shorter than the original and men with larger wrists will not be able to use it. The real problem is poor quality hardware. I wear my watch fairly loose, but after 22 days of use the metal clasp broke and the watch fell off. After 50 years of wearing all types of watches, I've never see the metal clasp of a strap watch break.

This absolutely works. I wasn’t sure if it would fit or if it would be too hard to attach, but it took less than three minutes. It’s too soon to evaluate the durability.
