Types of watch clasps

Hublot One Click System

Hublot pioneered the One Click System, a discreet mechanism that allows the strap to be changed with a single gesture. It is located next to the lugs and is designed to facilitate customisation, something highly valued in its most versatile models. It is commonly found on smaller watches, with a wide choice of straps in a variety of materials and colours.

QuickSwitch by Cartier

In the Santos collection, Cartier incorporated the QuickSwitch system, which works by means of a small lever hidden between the lugs. Simply press it to release the strap and snap on another one with a simple click. No tools are required, making this mechanism a practical solution for those who enjoy adapting their watch to different contexts.

Omega Quick Change System

In models such as the Seamaster Diver, Omega has developed its own Quick Change System. The wearer can release the pins via a hidden button and replace the bracelet with a rubber or textile strap. A functional detail that is appreciated by those who alternate between sport and everyday wear.

Other brands

Longines, Panerai or Chopard have also introduced similar systems, which enhance versatility without compromising the aesthetics or the solidity of the watch. Changing the strap is, in many cases, a matter of seconds.

On watches designed for more active use, whether sporty or professional, it is common to find micro-adjustment clasps. These solutions allow the bracelet to be adjusted without the need for tools, whether for comfort, temperature changes or use on technical garments.

• Internal folding extensions: these allow you to add a few millimetres to the bracelet by deploying hidden links.
• Serrated or sliding rails: allow you to adjust the clasp without removing or adding links.
• Extension for diving suits: present in brands such as Tudor or Omega, they are designed to wear the watch on neoprene without sacrificing the security of the clasp.

These are details designed for those who need a perfect fit at all times, without complications.

On high-value watches, and especially in certain contexts, the security of the clasp comes into play. Some brands have gone beyond the classic double button.

• Internal micro-locks or key locks: these prevent accidental opening and make theft more difficult. Although they are not very visible, they are designed to resist.
• Security films: these are applied over the lock and act as a seal. If it is tampered with, it is marked. It is a solution used mainly on leather or traditional locking models.

Standard folding clasp

It is one of the most common, especially on watches with metal bracelets. It folds into several sections and secures the watch firmly. It is used by brands such as TAG Heuer or Longines, which prioritise reliability and robustness.

Folding butterfly clasp

It has two hinges that open symmetrically and are hidden under the strap when closed. This solution allows the strap to be seen continuously, without interruption. It is typical of elegant watches such as those from Breguet or Frederique Constant.

Push-button release clasp

Integrates small buttons on the sides of the clasp. To open the clasp, they must be pressed simultaneously. It offers extra security against accidental opening. It is frequently used by brands such as Chanel, Tissot or Chopard.

Sliding clasp

It works by friction or internal rails, without the need for visible holes. It is present on technical straps, such as rubber or silicone, and is seen on models by Panerai, Rado or Ulysse Nardin. It is very practical for those who adjust their watch frequently.

Diver’s clasp for diving

Specially designed for diving watches, these clasps allow the watch to be worn over a wetsuit without losing stability. Omega, Tudor or Breitling have perfected these systems to the point of allowing millimetre-perfect adjustments even with just one hand.

The trend in haute horlogerie is clear: ever more complete clasps, integrating quick-change, micro-adjustment, security and extension systems. What was once exclusive to technical watches has now also found its way into dress models, offering the wearer more freedom without sacrificing elegance or precision engineering.

Today, the clasp of the watch goes beyond its practical function, it reflects how the piece is worn and says a lot about the personality of the wearer.
