NiziruoupWatch Band Quick Release Fluororubber 19mm 20mm 21mm 22mm Soft Durable Universal FKM Rubber Replacement Band Strap for Men Women

As another reviewer pointed out here, this strap is quite a good find at 19 mm; this can be a tricky size to find. It wears quite comfortably and looks great! The quick release spring bars are a pleasure to work with, they are so easy to install and change watch bands with. A minor criticism here is that I find the keepers to be a little bit flimsy. Also, the underside of the strap can leave a mark on your wrist but these are relatively minor complaints, especially at such an affordable price.I can be real picky about the weight of a watch and sometimes look for options other than bracelets. Even though the bracelet that came with this watch is very very fine, I found it a little bit heavy on the wrist, and wanted an attractive rubber or a silicone type that could handle water resistance and yet look kind of stylish and attractive.

I'm not much of a rubber strap guy as I prefer steel bracelets, but I recently needed a new strap for my Citizen Promaster and I decided to go with this one. This strap is excellent qaulity and feels very premium. The material seems very durable, but it's not stiff like some high-end luxury rubber straps. It's quite soft and supple and feels great on the wrist. I highly recommend this strap, you really can't beat it for the price.

Don’t buy this if you’re expecting a defective strap that feels cheap, because this one’s is exactly the opposite! Great value for money! The strap feels comfortable and is easy to install on a 20mm lug

I have bought way too many watch bands over the years only to be disappointed by the fit, finish or feel. This one feels and looks amazing! As soon as I tried it on I ordered a blue one for one of my other watches.

The media could not be loaded.  For the price this band is great. Perfect for the beach or outdoors. Picked up 20mm grey band for a Manchester Watch Works Blobfish dive watch.

This watchband is awesome. Great quality and easy to use. Looks and feels amazing.

FKM is the GOAT of rubber strap materials and this is one of the better ones I've found at this price point. The surface on this one is a little tackier than you usually see with FKM, but it's not sticky by any means. Super comfortable and big bonus points for having a 19mm option.

Not blue, that’s about it. Compared to the nice blue of a Seamaster, it’s way more purple in hue. Unfortunately it has to go back

The rubber is super soft and comfortable. Can’t believe the price

It's pretty thick FYI
