The proper fit of a wristwatch on your hand is crucial, both for aesthetics and comfort during use. To perfectly adjust your wristwatch strap, you need to be familiar with measuring, replacing, and adjusting the strap and clasp. In this article, we will guide you through these steps comprehensively and step by step.

How to Measure the Watch Strap

Before proceeding, first, determine the exact circumference of your wrist. There are two methods to measure your wrist:

Using a tailor’s tape or ribbon and string: Wrap the tape or string around your wrist where the watch strap normally sits and mark the point.
Record the measurement: Note down the measurement on paper. This will help you choose the right watch strap size.

Parts of a Watch Strap

A wristwatch strap is generally divided into three parts, regardless of its material:

The upper part: This connects to the watch case and can either curve to fit snugly against the case or remain flat with a slight gap. For metal straps, a flat connection might cause minimal wear and tear. However, if leather straps fit snugly without a gap, they may wear out faster, especially if not designed with a protective plastic layer.
The middle part: This forms the main body of the strap.
The lower part: This connects the strap to the clasp.

Best Strap Sizes for Men’s and Women’s Watches

The size of the watch strap generally depends on the size of the individual’s wrist and the style of the watch. For women’s and men’s watches, the standard strap sizes are as follows:

Women’s Watch Strap Sizes:

Strap width typically ranges between 12 to 16 mm.
Strap length usually fits wrists measuring 17 to 20 cm and is often adjustable.
Metal straps may extend up to 23 cm.
Slim and classic designs may have narrower straps, while sporty or modern designs may have slightly wider ones.

Men’s Watch Strap Sizes:

Strap width generally ranges between 18 to 22 mm.
Strap length usually fits wrists measuring 20 to 22 cm.
Metal straps may extend up to 25 cm.
Sporty or larger watches may have straps 22 to 24 mm wide, while classic or formal watches might have narrower straps.

In the end, the best strap size depends on individual comfort and style, which may require adjustments.

Types of Watch Straps and How to Shorten Them

Watch straps come in various types and materials, such as leather, steel, silicone, and nylon. Choosing the right type of strap is something you may not always consider when buying a watch. Our recommendation is always to choose a metal strap, also known as stainless steel, when purchasing a watch. This is because it offers more flexibility in adjusting and shortening the strap, and the cost of replacing a steel strap with other types is lower. To adjust and shorten a watch strap, it's important to know that each type of strap has its own specific adjustment method.

Leather strap watch

Tools needed: Small screwdriver or punch

Adjustment method:

Open the strap clasp and loosen the small screws that attach the strap to the watch case using the screwdriver.
Using a sharp object such as a small awl or punch, create a hole at the point you have already measured according to your wrist size.
Finally, after attaching the strap to the case, tighten the screws at the connection point to ensure the strap is securely fastened.

Metal strap watch

Tools needed: Special tool for removing steel straps (holder and pin remover)

Adjustment method:

Using the special tool, remove the small pins that connect the links of the steel strap.
Separate the extra links and shorten the strap to your desired size.
Reinsert the pins into their place and secure the strap connection.

Note: Shortening a metal watch strap is generally more common and practical. However, if you plan to do this yourself, make sure the strap is not made of ceramic or any other brittle material. Additionally, shortening or adjusting leather, silicone (rubber), and canvas (fabric) straps may be more challenging. For these types of straps, we recommend visiting a professional watch technician or repair expert.

Watch Strap Replacement

If you want to replace your watch strap with a new one, follow these steps:

Remove the old strap: Use the appropriate tool to detach the old strap from the watch case.
Install the new strap: Attach the new strap to the watch case in the same way the old one was installed.
Check the strap's tightness: Make sure the new strap is securely attached to the case and won't come off easily.

Note: Replacing a metal (stainless steel) strap with a new one might be more difficult, so be sure to consult a reliable expert or technician.

Measuring and Adjusting the Watch Clasp

To select and purchase the right watch clasp, after choosing the strap, you must measure the connection area between the strap and the clasp. The clasp should be adjusted so that it opens and closes easily, while also holding the watch securely on your wrist. It’s recommended to seek advice from watch experts to ensure the correct fit.

Final Words and Important Tips

Be patient: Adjusting the strap and clasp of a watch requires precision and patience.
Use the right tools: Using inappropriate tools may damage your watch.
Seek help from a watchmaker if needed: If you encounter difficulties with these tasks, it's best to consult a professional watchmaker.

By following these tips, you can easily measure, replace, and adjust your watch strap and clasp, allowing you to enjoy your watch. Additionally, keep in mind that some smartwatches and digital watches have specific methods for adjusting the strap and clasp. For these types of watches, it's recommended to refer to the user manual or consult a reliable expert.
