With these guides, you can confidently choose the perfect straps and accessories to enhance your watch.
2) Print File. In print options dialogue box, uncheck any “shrink oversized pages to fit” or “fit to page” boxes.*IMPORTANT!*
3) After printing, test the accuracy by measuring the “one inch” test strip with a standard ruler.
4) Cut off the inch ruler from the side and wrap around your wrist to determine your wrist size.
5) Hold your watch with the lugs framing the blocks below to determine your lug width. There should be no gap or overlap.
Lug Width Measurement:
To determine your lug width, print the BluShark Watch Sizing Guide in step-1 and place your watch on the measuring blocks located on the bottom of the guide.

2) Print File. In print options dialogue box, uncheck any “shrink oversized pages to fit” or “fit to page” boxes.*IMPORTANT!*
3) Cut out the tool. Position the wider end where you would wear a watch. For a more accurate measurement, you can use a piece of tape to hold the wider end in place.
4) Wrap the tool around your wrist, keeping it in place. Make sure the tool feels snug and doesn’t slide up or down.
5) Note the inch number the arrows point to – that’s your band size.
6) If the arrows land between two measurements, choose the smaller of the two numbers closest to the line.
Adapter Measurement:
To determine which size adapter you need, use the following guide:
If your Apple Watch is 42mm, 44mm, or 45mm, you’ll need an adapter that measures 22mm.
If your Apple Watch is 38mm or 40mm, you’ll need an adapter that measures 20mm.
If you have a 41mm Apple Watch, choose the 20mm adapter.
Unsure of your case size? You can usually find it on the back of your Apple Watch, near the sensor. Or, open the Apple Watch app on your iPhone, go to "My Watch" at the bottom, then tap General > About.

On-trend yet timeless.
Herringbone is one of those patterns that feel elegantly classic and thoroughly modern all at once.
This single-pass strap doesn’t mess around.
To make sure it’s a look that gets the look, we’ve made the SharkFin watch band with an oh-so-subtle medium sheen. Glossy but not too glossy with just enough of that sun-kissed pop to really highlight the uniqueness of the pattern.
Available in 6 classic colors – check out our unreal price for the whole bundle – means matching is a breeze and the sliding keeper ensures excess length won’t be flapping in the wind. It’s all about the details.
As with everything we do; if it’s BluShark, it’s guaranteed for life.
SharkFin Collection
Color: Black, gray, yellow
Unique W-weave creates a zig-zag "shark fin" pattern

Love this strap! It's thick but soft, the pattern looks sharp and the color goes with pretty much anything. Most comfortable strap I own so far.

Blushark Straps is always a pleasure to deal with. Quality watch straps, great prices and awesome customer service.
Kenneth R.4/5Verified
I’ve been buying from Blushark Straps for about a year now and they quickly became my go-to watch strap supplier! Just recently discovered this specific style NATO and I’m impressed. Love that it’s single pass and the textured zig zag pattern is a nice touch. Great quality overall. I got the black, blue, and green with the buy 2 get 1 free deal. Would definitely recommend!

I’m a strap man. Bracelets are annoying and get filthy. Pound for pound, best made for buck straps I have found. Color selection is fantastic! Built stout. Five star strap people. And believe me, I’ve got buckets of straps. These are Tier One.
Thomas W.5/5Verified
Good strap but slightly thicker than the knit weave!
Paul M.4/5Verified
I am live in Mexico, the package take longer to arrive, I notify you and all you tell me was thar I need contact with the courier, the problems was in USA, not Mexico, and is the sender who make the mistake, not me.
Samuel D.4/5Verified
Easily the most comfortable nato-style/single-pass strap I've ever worn and definitely the most elegant looking. I own 4 different colors and they all look fantastic (note for those interested: the titanium is a little darker in person than photos, still looks great, but leans more towards gunmetal than a bright silver).
Nick5/5
Great quality and good fit. I love every aspect of the strap.
William D.5/5Verified
Good quality.
Jim H.5/5Verified
Probably one of the softest straps I have ever used. Alot of these 1 piece straps are scratchy and hard, but this one is soft and not irritating to wear. It's not a traditional nato strap so you don't have the buckle security leg part of the strap. But this is a joy to wear. Highly recommend this strap.
Matthew E.5/5Verified
Great look and feel!
Brent P.5/5Verified
Good quality as all Blushark bands are, but I would not call this “silver”. More light medium grey with maybe a little green.
Karl T.4/5
I usually replace factory straps on most of my daily wearers. I purchased the cheap ones off of Amazon and some are stiff and itchy, not the best out there. I found BluShark straps by using ChatGpt and gave them a try. So far so good I love them. Softer and more comfortable. You get what you pay for with BluShark watch straps with a big selection.
Dean P.5/5Verified
Exactly what I wanted.
Matthew H.5/5Verified
love the initial experience of this strap. no fraying yet. maybe come back to this review in a few months for an update
Kevin P.5/5Verified
So, I typically wear Seiko family watches with Seichu bands - the fancy, deep color, oh-so-soft, Seiko branded, Japanese woven fabric band. So, if you know how those look and feel (and their price point) that’s the benchmark for this review.
I wanted some summer straps for other watches because leather and steel don’t suit our long, killer, summer heat.
So I bought a couple BluShark SharkFin bands and Wow! Am i impressed!
Deep ambiguous color, subtle bling in the weave, comfortable, lightweight, and easily long enough for an 8.75 inch wrist. These turned out to be a nice addition to a MeisterSinger Singuralis (dressy) and a Tag Heuer diver (toolly).
The seichu are still my benchmark - because i’m spoiled and i have to protect my ego to justify their expense ;) - but at 1/5 the price of a seichu band, SharkFins are a fantastic alternative!
Good show BluShark!
Greg Y.5/5
Good quality product.
Jim H.5/5Verified
Looks great on my Orient. Feels very comfortable on my wrist, subtle green tone yet very deep dark hue, just like I was hoping for. Material feels very good quality and strong.
Gabriel C.5/5Verified
I hated natos. Then I got this one. Very comfortable. I have it on my Seiko alpinist and this matches the dial really well. I really didn’t want leather during the summer and I don’t like the way bracelets look on the alpinist. This strap saved me from having to retire the watch for the summer. Thanks guys!
James W.5/5Verified
Good strap. Easy to install. Very comfortable and looks great.
Blake F.4/5Verified
I like this strap a lot. It's softer than other nylon straps I've worn, but not so much that it loses its shape.
Matthew F.5/5Verified
The SharkFin - Bond 2021strap was very pretty but it was also flimsy. The holes for size adjustment frayed right away, then putting it on a different watch it started separating. I would not recommend this strap.
Ricardo C.2/5Verified
Gorgeous blue color, and very high quality!
Joshua5/5Verified
The strap started freying quickly, and when I wrote an initially negative review, BluShark got back to me to offer me some solutions, it seems to me that this isn't too common of a problem.
You can buy similar blue herringbone straps for less, so note that you are paying extra
but it seems it goes toward exceptional customer service.
My negative experience turned into a positive one, so thank you to Nick for reaching out and I would recommend this strap.
William5/5
This is an overpriced and generic watch strap and is not made by BluShark. You can find it online quickly just by typing "Blue Herringbone Watch Strap" but you'll find them at half the price.
I bought one from BluShark and was dissappointed that for 53 euros (with international shipping) it started freying quickly.
The watch strap looks phenomenal but avoid BluShark since they substantially overcharge for the product.
William2/5
Quality straps with fast delivery.
Tracy5/5Verified
Loved dealing with Blu Shark and the quality of the strap far exceeded my expectations. I’ve bought NATO straps elsewhere but will now only buy from Blu Shark. Plus they sent a nifty extra strap gift!
Aliza M.5/5Verified
This Titanium strap is a beauty. The Sharkfin texture gives it a bracelet look. It goes great with either one of my watches. I wish it came in polished finish too, not just brushed.
Hector E.5/5
This used watch was gifted to me at work. It was nice but the old band did not fit. I got this sharkfin bond 2021 band and it looks great in it. My only concern is that the passers are not big enough to allow to fold the excess straps back on itself without difficulty. Or may be the strap is too thick for the passers.
Hector E.5/5
Awesome strap as always.
Jon C.5/5Verified
Excellent buying experience. I'm not sure about the combo with my green diver, and the strap is awesome. The quality is too notch, especially compared with other purveyors I've purchased from. The comfort is amazing and the length is on point for my 7.5" wrist. The hardware is excellent too, high quality with nice beveling and brushing. Punches way above its price. High value proposition.
Frederick V.5/5
Looks great on my blue Capt Willard. Really like the Shark Weave pattern on the strap.
Michael T.5/5Verified
Love the look with my two tone watch, Seemed to fray easily at the holes.
Peter3/5Verified
The strap is very comfortable. However it is much darker than it looks in the photos (almost black), the nylon on the adjustment holes are starting to fray a little bit. Overall its very good, but not perfect.
Vinay G.4/5Verified
I will start by stating that in my opinion BluShark bands are simply THE BEST watch bands you can buy! I have several BluShark bands from the Nautilus One collection, all of which have been used extensively on my Citizen Promaster dive watch.
Recently I bought a Seiko King Samurai dive watch. At first I used the original rubber band that came with the watch, but I was never in love with it. As with all traditional rubber bands there is a possibility that one spring pin could fail, potentially causing the watch to fall off your wrist. This could prove to be disastrous if you are in the ocean, etc.
Another problem with the original band was that it only included one large, stainless steel keeper on the band. Long sleeves usually caused the keeper to work itself loose, again potentially causing the entire watch to fall off the wrist.
To remedy these problems I went to my GO TO band company, BluShark. I decided to try the Sharkfin W-weave band and it is FANTASTIC. The Sharkfin W-weave uses a slightly thicker material than the Nautilus One (1.6mm vs 1.2mm) and I thought this would be fitting since the Seiko is a heavier, more rugged dive watch. To sum up the review I would say that the Sharkfin W-weave is ABSOLUTELY PERFECT for this watch. The extra thickness of the band keeps the watch head in place with no sliding or movement at all. The length is great, the stainless steel hardware is of great quality, and the band never comes loose, regardless of long sleeves. The Sharkfin W-weave is HIGHLY recommended if you want a quality band for your favorite watch.
Love this strap! It's thick but soft, the pattern looks sharp and the color goes with pretty much anything. Most comfortable strap I own so far.
