This watch strap is of excellent quality, but there is one problem: it is made only for people with small wrists; unfortunately, it is too small for those of us with slightly larger wrists. I don't know why they make these straps in only one size—apparently, they think only people with small wrists can afford more expensive watches.
I suggest they also produce XL straps for those with wrists larger than 20 cm; then they would deserve 5 stars.
Initially I was disappointed to find out the strap did not fit my watch but as it turned out, I was sent the wrong strap. Watchbuddys went above and beyond to identify the problem (via photo request) and overnighted me the replacement strap. Fits like a charm and super comfortable. I have high hopes this will last a long time. The quality seems superb.
Hey buddy,
Really glad we could sort the mix-up out for you. Standing behind every order and going the extra mile is exactly what we aim for. Thanks for sticking with us.

Turns out I was sent the wrong strap. Wristbuddys realized their mistake and sent me the right straps immediately. Wearing as I write this review and it's very comfortable. To be determined on longevity and durability but I'm optimistic this will be my go to strap throughout the summer. Thank you!

Really a big fan on the SMP straps , will likely to get the second one with the deployant clasp

very good quality strap. I wish they made a deployment strap in this style but other than that it's great. I may purchase a great strap for my Aqua Terra Seamaster. The shipping was fast.
Hey buddy,
Happy to hear you like the quality and that the strap worked great on your Seamaster. Fast shipping and solid fit is exactly what we aim for.
And noted on the deployant idea. Always good feedback.

The quality of the product is really good. It feels smooth on the wrist, even better than the original. The only feature which I am missing is the fixation for the movable keeper. But still worth five stars.

The strap did fit my 2004 omega sea master perfectly but it was to short. After install it put it on my wrist and was on the last available hole. Yes I am a bigger guy with heavier wrist but I've never run into this issue before. Good quality just needs to be longer

J'ai acheté 5 bracelets pour ma Seamaster bleue et noire, et ils sont géniaux, bien meilleurs que l’original d’Omega. Je suis très satisfait, j’en ai parlé à tous mes amis et je commanderai d’autres bracelets ici pour mes montres. 😊
