Finding the perfect strap or accessory for your watch can greatly enhance comfort and style. Our sizing guides help you measure your watch accurately, ensuring the best fit. Whether you have a traditional watch or an Apple Watch, we provide step-by-step instructions to determine the ideal strap size and watch lug width. With these guides, you can confidently choose the perfect straps and accessories to enhance your watch.

Watch and Watch Strap Measurements Sizing Guide

• Traditional Watch Instructions:

1) Open Our Sizing Guide Here. Download Here

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. 

 

• Apple Watch Instructions

1) Open Our Apple Watch Sizing Guide Here. Download Here

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.

    The Divecore FKM HP Professional Diving Watch Strap features pre-installed Apple Watch adapters for a seamless fit. Originally designed for Swiss dive watches, it’s the ultimate strap for water sports and aquatic adventures.

    Designed for flexibility with a unique mono-accordion pattern that won’t get in the way of the keeper. It also features a flat pin buckle and flat adjustment holes along the strap for easy micro adjustments. The strap’s locking feature ensures it stays secure, even under dynamic pressure.

    Spring Bars: The Apple Band Divecore Bands come with BluShark 1.7mm spring bars instead of the standard Divecore fat spring bars to ensure a better fit with the adapters.

    American FKM Rubber: This formula is known for its superior resistance to heat, chemicals, and weathering compared to other rubber materials. It's often used in applications that require durability, such as in the aerospace industry.

    What sets American FKM rubber apart from other formulas, like standard FKM or silicone rubber, is its specific chemical makeup, which is formulated to perform better in extreme environments. American FKM tends to offer:

    1. Higher Heat Resistance: Can withstand temperatures as high as 300°F (150°C), which is ideal for use in extreme conditions.
    2. Chemical Resistance: Resists oils, fuels, solvents, and acids better than many other elastomers.
    3. Durability: It tends to have a longer lifespan in harsh conditions, making it ideal for long-lasting products, like watch bands exposed to sweat and moisture.
    4. Elasticity: Despite its strength, it maintains flexibility and a comfortable feel, which is great for wearable items.

    Super comfortable, feels heavy duty and durable too. I like that it feels really breathable and my wrist hasn’t felt uncomfortable or or sweaty even on hot days. Really easy to install and remove as well which is always a huge plus. I was definitely hesitant being it’s a 60 dollar rubber strap but it was well worth it, much more comfortable than the official Seiko rubber straps.

    Great band, I have changed all of my Seiko Divers bands over to Dive Core Bands. I especially like that the second keeper locks onto the free end of the strap, and keeps the other one in place. Band feels good while wearing, and by all that I can tell will last a long time. I did change out some of the spring bars to the fat Seiko ones and they work perfectly, however on the one Seiko sports model I have, I had to use the QR pins that came with the strap. I would defiantly recommend these to a friend!

    Customer photo review of Divecore - American FKM - FKM Rubber HP Professional Diving Watch Strap - Navy Blue

    Divecore makes some of the best rubber straps on the market. Every edge of the strap is rounded off, so nothing digs in and causes discomfort. The close hole spacing and the slight give offered by the accordion design make it easy to get a good fit. My first Divecore strap was the previous generation FKM in blue; the previous generation blue didn’t quite match my Citizen Fujitsubo. This new navy blue is spot on, and the American FKM feels a little bit softer and less tacky than the previous FKM formula. My only gripe about these straps is the use of a thin, 1.5mm spring bar at the buckle, which negates the beefy spring bars at the lugs. On all of the Divecore straps I’ve owned, I swapped it for a slightly thicker 1.7mm bar, which fits perfectly and makes it a little more solid. I would really like to see Divecore develop a solid screw-in buckle like what Isofrane uses and sell it as a separate upgrade. Overall, that is a minor complaint, and these are 5 star straps, especially for the price.

    Ideal company to work with. Great strap selection and competitive pricing. The Divecore HP FKM strap is outstanding! The strap is well made and comfortable. What I really enjoy is the keeper tab that won’t let keepers slide off the strap. Highly recommended!
