Replacement Buckle Guide for Audemars Piguet Royal Oak & Royal Oak Offshore
This guide introduces the main types of Audemars Piguet buckles and clasps, with a focus on the Royal Oak and Royal Oak Offshore collections. We will explain the different clasp types, common sizes, and key compatibility considerations to help you choose the right replacement buckle or clasp for your watch.
Whether you wear an Audemars Piguet Royal Oak, Royal Oak Offshore, the 15703 Diver, or a Code 11.59, choosing the correct buckle is important when replacing or customizing a watch strap. The strap width, buckle-end width, attachment system, and exact watch reference should all be considered before ordering.

We also offer custom strap options based on your watch model, strap dimensions, and wrist size, providing a practical and cost-effective alternative for everyday wear.

What Types of Audemars Piguet Buckles Are Available?
Audemars Piguet straps commonly use two main types of buckles: tang buckles (pin buckles) and deployant or folding clasps.
Audemars Piguet Deployant / Folding Clasp
An Audemars Piguet deployant clasp, also commonly called a deployment clasp or folding clasp, is a folding fastening system that keeps the strap attached to the clasp when the watch is opened and removed from the wrist.
The terms deployant clasp, deployment clasp, and folding clasp are often used interchangeably when referring to this type of watch clasp. However, the actual clasp construction, dimensions, and attachment system can vary between Audemars Piguet collections and references.
For Royal Oak and Royal Oak Offshore replacement straps, it is therefore important to check the exact watch reference, strap width, buckle-end width, and attachment system before choosing a replacement clasp.
For more information about the different parts of a watch strap, see our Leather Watch Strap Parts Name Guide.
Audemars Piguet Tang Buckle
A tang buckle, also known as a pin buckle, uses a buckle frame and pin to secure the strap through the adjustment holes. It is commonly used with leather and rubber straps and can be easier to pair with replacement straps when the correct buckle-end width is confirmed.
Clasp For Royal Oak vs For Royal Oak Offshore
- The Royal Oak bracelet is an integrated design, and AP’s historical documentation shows that its folding clasp has evolved through multiple generations.
- Newer Royal Oak Offshore models use AP’s interchangeable strap system, with the strap and buckle system integrated into the case and designed for quick release. AP notes that some legacy Offshore models can be converted to the self-interchangeable system with a specific conversion kit.
Common Audemars Piguet Clasp Sizes
| Watch Series / Model | Buckle End Width | Buckle Type | Notes | Model Code |
|---|---|---|---|---|
| Royal Oak (Standard / Traditional) | 18mm or 20mm | Tang (pin) / Deployant (folding) | Depends on case size and vintage | Royal Oak |
| Royal Oak Offshore (42mm models) | 20mm or 22mm | Tang / Deployant | Subject to strap specification | Offshore 42mm |
| Royal Oak Offshore (Larger / Diver models) | 20mm / 22mm / 24mm | Tang / Deployant | Mostly for wide rubber or leather straps | Offshore Diver |
Example: AP Royal Oak Offshore 42mm
Many 42mm Royal Oak Offshore replacement straps use a wider 28mm watch-side connection, while the buckle end can taper to 20mm. Therefore, 28mm strap width does not mean you need a 28mm buckle.
| Buckle Type | Strap Configuration | Common Application |
|---|---|---|
| 20mm Tang Buckle | 28mm × 20mm | Some Royal Oak Offshore and 15703 Diver replacement straps |
| 24mm Tang Buckle | 28mm × 24mm or 30mm × 24mm | Wider Offshore configurations, including some 15703 and 44mm Offshore setups |
Popular Royal Oak and Royal Oak Offshore references include models such as:
- Royal Oak 15400
- Royal Oak 15500
- Royal Oak Offshore 15703
- Royal Oak Offshore 15710
- Royal Oak Offshore 26470

How to Measure an Audemars Piguet Buckle Before Buying Replacement Clasp
Can I Use the Original AP Clasp With a Replacement Strap?
In many cases, a replacement strap can be designed to work with the original Audemars Piguet clasp, but compatibility depends on the exact strap-end construction and dimensions.
For example, some replacement AP straps are specifically made to fit the original AP quick-release clasp without including a new clasp.
Replacement Buckle For AP vs Original AP Clasp
A compatible aftermarket clasp can be useful when the original clasp is damaged, worn, or when you want to build a replacement strap setup at a lower cost.
| Feature | Original AP Clasp | Compatible Replacement Clasp |
|---|---|---|
| Original AP component | Yes | No |
| Finish / branding | Original | Aftermarket |
| Price | Typically higher | Typically lower |
| Strap compatibility | Reference-specific | Depends on specification |
| Replacement use | Original restoration | Everyday / replacement use |
What Should I Check Before Buying an Replacement Buckle for AP ?
1. Buckle-End Width
2. Clasp Type
Folding clasp
Tang buckle / pin buckle
3. Attachment System
Some new Offshore models feature an interchangeable system.
4. Material and Color
Stainless steel
Titanium
Black
Rose gold tone
Yellow gold tone
If your AP strap is still in good condition but the buckle has developed scratches, corrosion, loose components, or other signs of wear, replacing the buckle may be a simpler and more cost-effective option than replacing the entire strap.
For example, you may want to replace the buckle if:
- The buckle surface has heavy scratches
- The buckle pin or hardware is worn
- The clasp no longer closes securely
- Internal components have become loose
- You want to use a different strap with a compatible buckle
For an original Audemars Piguet clasp, professional inspection or servicing may be appropriate when the component itself requires repair.
For everyday replacement use, a compatible third-party buckle can provide a more affordable alternative when the correct dimensions and attachment system are confirmed.

Q:Is an AP deployment clasp the same as a folding clasp?
A:The terms are often used interchangeably to describe folding-style clasp systems, but the exact design can vary between AP models and generations.

A:In many cases, yes, provided that the replacement strap is manufactured with the correct buckle-end dimensions and attachment configuration.
