Size (Lug Width)
How to Find Your Lug Width
The lug width of a watch is the distance (in millimetres) between the two lugs that hold your strap or bracelet in place. Your strap must match this measurement exactly to fit correctly.
What Is Lug Width?
Lug width is measured between the inside edges of the lugs. It is always measured in millimetres, not inches. If your watch has a 20mm lug width, you need a 20mm strap to fit.
The Easy Way (Recommended)
Our clever people at MGBWATCHES have built a handy Strap Size Checker with a database of 40,000+ watches. Simply search your brand, model, or reference number, then select the matching lug width shown. It takes seconds and removes all guesswork.

Two Ways to Find Your Lug Width Manually
Method 1: Online Search
- Locate the exact model or reference number of your watch. This can usually be found on your warranty or authenticity documents.
- Search: [brand] [model number] lug width
- Example: Omega 310.30.42.50.01.001 lug width
Method 2: Measure It Yourself
To measure your lug width accurately, you’ll need the strap or bracelet removed.
- Remove your existing bracelet or strap.
- Measure the distance between the lugs using a ruler or vernier calliper.
- Measure in millimetres only.
For safe, scratch-free removal, we recommend our Bracelet Removal Tool, designed for collectors and everyday use. It makes strap changes quicker, cleaner, and far less stressful.
Strap Size Guidance
- Lug widths are usually whole numbers such as 18mm, 19mm, 20mm, 21mm, or 22mm.
- Our straps are available in 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, and 24mm.
- The strap size you select must match your watch’s lug width exactly.
- Example: If your watch has a 21mm lug width, you need a 21mm strap.
Note: If your lug width is not a whole number (for example 21.5mm), please contact us and we’ll advise the best fit.

Product Description
Designed for everyday wear, the sailcloth deployant strap is built for durability, comfort and long-term use. This is a strap made to be worn properly, exposed to movement, water and daily life, while still looking right on the wrist.
The outer layer is a tightly woven sailcloth fabric chosen for its strength and resistance to wear. Beneath this, a softer lining sits comfortably against the wrist. Reinforced FKM rubber notches are integrated in high-stress areas to improve longevity and reduce fatigue over time.
A stainless steel deployant clasp provides a secure and consistent fit, spreading pressure evenly across the wrist and avoiding the repeated bending associated with traditional pin buckles. It also makes the strap easier to put on and take off, while helping it maintain its shape with regular wear.
Sailcloth sits comfortably between materials. More structured and refined than rubber, more resilient than leather, and cleaner in appearance than traditional fabric options. It performs well in wet conditions while remaining suitable for everyday use, making it a versatile choice for collectors who wear their watches rather than rotate them.
Available in a range of colours and sizes to suit modern watches from 18mm to 24mm lug widths.

Best deployant watch straps for everyday wear
Deployant watch straps are often associated with bracelets, but in recent years they have become a preferred option across rubber, sailcloth, and fabric straps. For collectors who wear their watches regularly, the appeal is simple. A deployant clasp improves comfort, keeps the strap in better condition, and makes the watch easier to live with day to day.
Unlike a traditional pin buckle, a deployant clasp opens and closes through a folding mechanism. Once sized, the strap does not need to be pulled tight through a buckle each time it is worn. This reduces stress on the strap and creates a more consistent fit on the wrist.
Over time, the difference becomes obvious. Straps hold their shape better, wear more evenly, and feel more comfortable during long periods of use.
What a deployant clasp does in practice
A deployant clasp secures the watch by folding rather than pinning through a hole. Once adjusted, the clasp opens and closes cleanly, allowing the watch to be put on and taken off without forcing the strap into the same position repeatedly.
In everyday use, this brings a few clear advantages:
- Less strain at adjustment holes
- Reduced creasing and stretching over time
- More even pressure across the wrist
- A consistent fit every time the watch is worn
For collectors who rotate watches or swap straps regularly, deployant clasps also help keep straps looking better for longer.
Pin buckle straps are familiar and functional, but they concentrate wear in one place. Each time the watch is worn, the strap bends sharply at the same hole. Over months of use, this leads to creases, distortion, and eventually failure.
Deployant straps avoid this problem. By spreading movement across the length of the strap, they allow the material to curve naturally around the wrist. This is particularly noticeable on straps worn daily, or on watches with a bit of weight to them.
For many collectors, deployant clasps are less about appearance and more about preserving the strap over time.
Choosing the right deployant strap material
Material choice plays a large role in how a deployant strap feels and how well it holds up in use. Each material brings a different balance of structure, flexibility, and comfort.
Sailcloth deployant straps
Sailcloth is a tightly woven material originally developed for demanding environments. On the wrist, it offers structure and durability without feeling stiff or fragile.
Sailcloth deployant straps work well on watches that see regular wear, including chronographs and divers. They resist abrasion, handle moisture well, and keep their shape over time. For many collectors, sailcloth sits in a comfortable middle ground between rubber and leather.
FKM rubber deployant straps
FKM rubber is widely regarded as the premium standard for rubber straps. It remains flexible, resists UV exposure, and stays comfortable against the skin, even during long wear.
Paired with a deployant clasp, rubber becomes more refined and easier to live with. The clasp removes the constant bending seen with pin buckles and gives the strap a cleaner, more finished look on the wrist.
Rubber deployant straps are a popular choice for sports watches, divers, and watches worn in warmer conditions.
Nylon deployant straps
Nylon deployant straps offer a lighter feel while still benefiting from the structure of a folding clasp. They are breathable, comfortable, and well suited to casual daily wear.
The deployant clasp helps nylon straps maintain their shape and fit, avoiding the loosening and distortion that can develop over time with traditional fabric straps.
For many collectors, deployant clasps are less about appearance and more about preserving the strap over time.
Deployant straps for Omega, Tudor, and Rolex watches
A deployant strap should feel like a natural extension of the watch, not an afterthought. Proportions, thickness, and clasp size all matter.
Our deployant straps are selected to pair cleanly with watches from Omega, Tudor, and Rolex, as well as MoonSwatch models and other modern sports watches. Attention is given to lug width, case shape, and how the strap sits against the wrist when worn.
An OEM-style deployant strap should look intentional. The goal is balance, comfort, and a fit that feels right from the first wear. Read more about pairing with tool watches here
Are deployant watch straps worth it
For watches worn occasionally, a pin buckle may be enough. For watches worn most days, a deployant strap often proves its value over time.
Collectors tend to choose deployant straps because they:
- Improve long-term comfort
- Reduce wear on the strap
- Make the watch easier to put on and remove
- Maintain a consistent fit
Once worn for a period, many find it difficult to return to traditional buckles on watches they use regularly.
Will a deployant strap fit my watch?
Most watches that use standard spring bars can accept a deployant strap, but fit is not universal. Case shape, lug length, and strap thickness all play a part.
Our deployant strap collection focuses on designs that work with a wide range of modern watches. If you are unsure about compatibility, our strap checker can be found above.
