This is a quality bracelet that elevates the experience of wearing this watch. A must have upgrade for the SRPE lineup. Item arrived quickly and well packaged.

Exactly what Turtle needs, a proper bracelet, solid endlinks, screwpins, solid links & milled V clasp.. however I wish Anchor would review the flip lock clasp, too thick, no slide adjust just doesnt suite the excellent quality on the endlinks & oyster links .. i switched clasp to an AliExpress one, much slimmer, streamlined, easy adjust push diver extension now its the Ducks Nuts

Bracelet did not initially fit, but Brando was quick to respond and get a replacement link sent out. Happy to support a company that cares about their customers.

Positive:
Feels very secure
Above average quality
Fits the seamaster perfectly, no gaps
Negative:
Clasp is bulky
Also rattles a little bit
The color doesn’t 100% match the color of the case but doesn't bother me

This is the second Kumamoto bracelet I've purchased for the SRPE, and I've also got a Kumamoto CTS rubber strap for the SSK. The bracelets are far superior to what comes on the SRPE, and the rubber strap is just about perfect. Anchor straps are comfortable and fit like the original parts. You will not regret buying one.

Great bracelet and clasp. Top notch customer service. Brando sent over some free additional spring bars after having some trouble fitting the bracelet initially.
S
Way better than Uncle Straps and even better than StrapCode.
B
Perfect fit for my Seiko SRPE93. Blends in perfect and fits very comfortable on my wrist. Fair price for a good bracelet. Highly recommend
M
Awesome bracelet fits like a glove
A
Almost perfect it’s just missing micro adjustments.
B
Great bracelet.
T
Great product, however the mid link on the strap doesnt seem to sit flush in the endlink. I have emailed to see if this is correect and am waoting for an email back.
R
overall bracelet is well made. finish is excellent. one gripe on the fit is that on 1 of the endlinks, I have some difficulty connecting the bracelet to the endlink. fit is slightly off. took me some time to connect it. Happy with the purchase overall
W
Clean and classy. Will go great with my SRPE05.

I purchased this bracelet to try and see if it would fit my 42mm Omega SMP 300 with tAnchir’s 42mm SMP end links. To my surprise, it fits perfect and I’m not sure why Anchor doesn’t offer this bracelet with the end links that fit the 42mm SMP. I also have the Forstner oyster bracelet and have to say this is much better IMO.
B
I love this bracelet it fits so well and looks just like
It was made by the watch manufacturer because it fits the watch perfectly as well as my wrist. I will be buying more from anchor
C
The bracelet is really top quality. The fitment is excellent and this fits a need in the aftermarket bracelet market. I’ve been looking for a great Oyster for a while. I don’t love the clasp, but that is just a preference. The packaging is an excellent and the presentation is awesome too.
S
This is the best Turtle bracelet ever. Smooth, no sharp edges, and great brushing
R
Fantastic fit and finish on my Seiko SSK! I don’t prefer the jubilee style bracelet it comes on and as soon as I switched to the oyster style, I’m wearing it more often alongside my other watches
J
Best steel bracelet I have bought!
T
Really nicely built oyster style bracelet.
M
Perfect addition to my BB58
A
Overall a good quality product.

Tried other bracelets but this is the only one with the end links lining up with the lugs perfectly. Feels high quality and well made!
