ULLCHRO Fluororubber Watch Strap - Fast Release Cut-to-Size 18mm 19mm 20mm 21...

It seems to be of excellent quality. I really appreciated the inclusion of the spring bar removal tool and the spare spring bars that are supplied.

Ever since I bought my Gevril I hated wearing it because the leather band was too stiff and difficult to get the pin buckle on and off, ruining the unstiched leather after only a dozen uses. Now it's a joy strapping it on/off in seconds with the perfect fit achieved by cutting the straps, and/or adjusting the pins in one of three positions on the buckle.

Material does not attract dust/lint so it always looks good. The metal clasp is decent and does not pinch. Overall very comfortable.

love it!!!!!! if you have a problem with watch bands that never fit this one will fit (i heard 10"+ and that sounds reasonable; i have 8.5" and could have worn this over a light jacket.. plenty of room)... the double locking clasp is great, quick on off, love the color, 20mm fits Samsung 40mm Watch 7 fine and doesn't bind up.. plenty of room. in addition to adjusting the watch straps by cutting, there's a 3 setting adjustment on the clasp. comes with tools to remove standard (non quick) watch pins.. nice tool which i had that a long time ago. loved it so much i immediately ordered 2 more for safe keeping thanks!! excellent

Got a few of these because the price is unbeatable. Clasp was unexpectedly high quality; milled from a solid piece of metal rather than a cheap stamped clasp. Fantastic watch strap. It will fit any sized wrist, trust me... I have an 8" (200mm) wrist and there were like two extra inches to spare. If you've never had an FKM rubber strap, TRY IT.... it's WAY nicer than the typical cheap silicone. It's slightly heavier, more comfortable, and feels less sweaty. There's a reason why luxury brands use FKM rubber and not silicone. Some assembly is required; you will need to trim it to size. All very standard for this style of strap.

Mala calidad, es muy delgada y siento que se va a romper

This watch band is a full 20-cm long when ordered and is adjustable by cutting off ½-cm segments until it is the right size to fit your wrist with the watch attached. The butterfly clasp holds firmly and has a locking tab that keeps it from popping open unexpectedly. However, once cut to size, this band is not adjustable for accommodating fluctuations in wrist size. So sometimes it is going to be too tight, while other days it may be too loose. The kit comes with extra spring bars for both the strap-to-watch attachment and also for the strap-to-buckle attachment. The kit also comes with a tool that has a split flat end (to pull on the spring bar of your old watch band) and a sharp end to push on the end of the spring bar in the buckle attachment. The spring bars for the watch end have a pull tab that makes it super easy to pull back the spring to insert or remove the band from the watch. The spring bars for the buckle are not so easy to remove or insert, as the pin has to be pushed in until it fits within the edges of the buckle. The instruction guide that comes with the band does not show the same type of band. Although the same butterfly buckle is used, the band in the instruction guide uses a pin fastener (like a belt buckle) which has an overlapping end and holes at various points to adjust the length. What you actually get (and is shown in the Amazon listing) is a band with segments that have to be cut off in order to resize to fit your wrist. The problem with this is that there is no overlapping end - you have to cut the band to the exact length that is needed, and there is no adjustment beyond this (for days when your wrist swells or shrinks slightly). Once cut to the length that you need, the spring pin goes through the last segment of the band and clips into the retaining holes on the edges of the butterfly buckle. Also, if you cut off too many segments of the band, there is no fixing it. So be careful how many segments you cut off and size check it often. As it turns out, I wish I had left one extra segment on the band - it fits, but most days leaves an imprint of the buckle on my wrist. Once sized to fit, this watch band is attractive looking and smooth. The band fits comfortably on the wrist (so long as you haven't removed too many segments) and doesn't pinch the skin below the buckle. I do like the extra locking tab on the buckle which ensures that it doesn't open accidentally. Overall, this band feels very solid, and the pins seem to be strong enough to hold the watch firmly. My biggest complaint is that there is no adjustment once you have fitted it to size, so it isn't adjustable to occasional swelling or shrinkage of the wrist. And it was quite challenging to press the tiny ends of the spring bars into the buckle.

Nice rubber strap, cut to fit your wrist size. Good double lock deployment clasp.
