Choosing the right strap size is simple once you know your wrist measurement. This guide explains how to measure your wrist, adjust a Royal Oak–style metal bracelet, and choose the correct hole on a silicone strap.

How to Measure Your Wrist

Wrap a flexible measuring tape around your wrist at the point where you normally wear your watch.

Keep the tape comfortably close to the skin, but do not pull it too tightly. The measurement should feel similar to how you want the watch to fit.

When you do not have a measuring tape:

1. Wrap a piece of string or a narrow strip of paper around your wrist.
2. Mark the point where the ends meet.
3. Lay it flat against a ruler.
4. Record the measurement in centimeters or millimeters.

For example, a wrist measuring 17 cm is the same as 170 mm.

How Should the Watch Fit?

A properly fitted watch should feel secure without squeezing your wrist.

You should normally be able to slide one finger between the strap and your skin. The watch should not rotate freely around your wrist, but it should also not leave deep marks or feel uncomfortable.

Your wrist can expand slightly during warm weather or throughout the day, so avoid making the strap excessively tight.

Wrist-Size Examples

These ranges are general examples. The final fit can vary depending on the size of the watch case, the number of bracelet links, and the spacing between the holes on the silicone strap.

Real-Life Examples

Example 1: 15 cm wrist

A customer with a 15 cm wrist will normally need several links removed from a full-length metal bracelet.

With a silicone strap, they will usually use one of the tighter holes near the watch case. The remaining strap tail should sit securely inside the keeper loops.

Example 2: 17 cm wrist

A 17 cm wrist is a common medium size.

The metal bracelet may require two or three links to be removed, depending on the original bracelet length and the size of the watch case.

On a silicone strap, the customer will usually use one of the middle holes.

Example 3: 18.5 cm wrist

A customer with an 18.5 cm wrist may only need one or two bracelet links removed.

On a silicone strap, they will normally use a hole closer to the wider end of the adjustment range.

Example 4: 20 cm wrist

A 20 cm wrist will usually need most or all of the original metal-bracelet links to remain installed.

With a silicone strap, the customer will generally use one of the outer holes. Before ordering, confirm that the strap’s maximum wearable length is suitable for your wrist.

Adjusting a Royal Oak–Style Metal Bracelet

Metal bracelets are resized by removing or adding links.

How Link Sizing Works

Each removable link changes the bracelet length by a small amount. Removing links makes the bracelet shorter, while adding links makes it longer.

For the most balanced fit, remove links from both sides of the clasp whenever possible. This helps keep the clasp centered underneath your wrist.

For example, when four links need to be removed, it is generally better to remove two from each side rather than all four from one side.

Basic Adjustment Process

1. Open the bracelet and identify the removable links.
2. Look for screws or directional arrows on the inside of the bracelet.
3. Use the correct watchmaking screwdriver or link-removal tool.
4. Remove one link at a time.
5. Reconnect the bracelet securely.
6. Try the watch on before removing additional links.

Some bracelets use screws, while others use pins. Do not force a pin or screw in the wrong direction.

If the bracelet includes a micro-adjustment position inside the clasp, use it for small fit changes before removing another complete link.

Important Bracelet Advice

Keep every removed link, pin, screw, and collar in a safe place. You may need them later if your wrist size changes or if you sell or gift the watch.

If you are unfamiliar with bracelet sizing, we recommend visiting a local watchmaker or jeweler. Bracelet components are small, and incorrect tools can scratch the bracelet or damage the screws.

How Silicone Straps With Holes Work

A silicone strap normally has two sides:

• The buckle side
• The longer side with adjustment holes

To fasten the strap:

1. Place the watch on your wrist.
2. Insert the longer strap through the buckle.
3. Choose the hole that gives a secure but comfortable fit.
4. Insert the buckle pin through that hole.
5. Pass the remaining strap through the keeper loops.

Choosing the Correct Hole

Start with a looser hole and gradually tighten the strap until the watch sits securely.

The correct hole should:

• Keep the watch centered on your wrist
• Prevent the case from moving excessively
• Allow approximately one finger beneath the strap
• Avoid pinching or leaving deep marks

Do not choose the tightest possible hole simply to stop the watch from moving. A slightly comfortable fit is better for daily wear.

Between Two Holes?

Sometimes one hole feels too loose while the next feels slightly tight.

In that situation:

• Use the looser hole during warm weather or physical activity.
• Use the tighter hole only when it remains comfortable.
• Check whether the strap or clasp has an additional adjustment option.
• Avoid creating extra holes yourself, as this can weaken or tear the silicone.

Before Ordering

Please check:

• Your wrist circumference
• The minimum and maximum wearable strap length
• The connection shape
• The strap width
• The watch model compatibility
• Whether the buckle, adapters, screws, or tools are included

A strap may look similar while using a different attachment shape or measurement. Always compare the product specifications with your current watch before ordering.

Compatibility note: These straps are independently produced replacement accessories designed for selected Royal Oak–inspired and compatible watch cases. Please verify your exact watch model and measurements before purchase.
