How to choose the perfect strap for your watch? A complete guide

Guide: Choosing the right watch band width

Changing a watch strap is a simple way to give it a new look or extend its lifespan. But choosing the right strap width , one that fits your watch case, is crucial. An incorrect size will result in a poor fit, reduced comfort, and can even damage the lugs. In this guide, learn how to correctly measure the required width, and consult our compatibility chart by model and case size to easily find the right strap for your watch.

How do you measure the width of a watch strap?

The width of a bracelet corresponds to the internal distance between the two lugs of the case . This is also referred to as the “lug width”.

It is expressed in millimeters (16 mm, 18 mm, 20 mm, 22 mm, etc.).
A simple ruler or caliper allows for an accurate measurement.
Warning: a bracelet that is too narrow will be loose, a bracelet that is too wide will cause strain and may damage the watch.

The different materials of watch straps

Stainless steel

The steel bracelet is the most versatile: corrosion-resistant, comfortable, and compatible with most watch cases. It is available in Oyster , Jubilee , or Engineer link styles, with brushed or polished finishes. Ideal for a dress watch or an active lifestyle, it is water-resistant and easy to clean with soapy water.

Milanese mesh

The Milanese mesh , woven from fine steel, offers a sophisticated style and excellent breathability. Its precise adjustment via a sliding buckle makes it ideal for slender wrists. Perfect for modernizing a classic watch without sacrificing comfort.

PVD/DLC treated steel

Black PVD- coated steel or DLC (carbon-coated) bracelets enhance scratch resistance and provide a sporty look. Pair with a similarly treated case to maintain color consistency. Care instructions: Clean with a microfiber cloth; avoid abrasive products.

Titanium

A titanium bracelet stands out for its lightness and high resistance. Hypoallergenic, it is suitable for sensitive skin and for larger watches where weight is a priority. Its matte, technical gray finish complements dive watches and tool watches.

Ceramic

The ceramic bracelet is very hard and virtually scratch-proof, with a high-end, glossy finish. However, it is more brittle than steel, making it a better choice for refined urban wear. Link adjustments require the proper tools.

Calfskin leather (smooth, grained, saffiano)

A leather strap remains the epitome of chic for a dress watch. Smooth for a minimalist style, grained for texture, saffiano for durability. Keep it dry; alternating straps will prolong its lifespan. Compatible with pin buckles or folding clasps.

Alligator/crocodile embossed leather

Embossed alligator leather (or genuine leather, depending on the model) adds an iconic texture and a luxurious feel. Ideal for classic dials with Roman numerals. Choose a breathable lining for enhanced everyday comfort.

Nubuck / suede

Nubuck and suede offer a soft feel and a casual chic look. Very pleasant in the mid-season, they require dry care (soft brush, waterproofing spray) and remain sensitive to water.

Rubber / silicone

The rubber or silicone strap is perfect for sports and diving: waterproof, flexible, and easy to rinse. Grooved designs ( Tropic , Waffle ) improve ventilation and grip. Ideal for dive watches and compatible G-Shocks.

NATO / Zulu (nylon)

The NATO and Zulu nylon straps fit under the case back: enhanced security should a spring bar break. Lightweight, washable, and available in hundreds of colors, they allow you to change the style of a watch in seconds.

Perlon

Perlon is a breathable synthetic braid: ultra-breathable, adjustable to the millimeter without pre-cut holes, and very lightweight in summer. Its modern vintage look works well with slim cases.

Textile / canvas

The textile or canvas strap combines comfort and durability. Its matte, utilitarian appearance perfectly complements a field watch or military dial. Simple care: gentle hand wash and air dry.

Integrated bracelets / curved end-links

Some models require integrated bracelets or curved end links to fit the case. Always check the watch's reference number (Seiko, Citizen, Orient, etc.) and the exact lug width before purchasing to ensure compatibility.

Standard widths and compatibilities

The most common widths are 18 mm, 20 mm and 22 mm .

Some specific models (e.g., Casio G-Shock, Seiko Tuna) use special attachments that require proprietary bracelets.

Modern bracelets with quick release systems make changing them easier without tools, but the width must still be respected.

Conclusion: Choosing the right bracelet width is key.

Identifying the right strap width for your watch is a simple yet essential step to ensure both comfort and aesthetics. A properly sized strap enhances the dial, provides a secure fit, and prevents premature wear on the case. Whether it's a dress watch, a sports watch, or a dive watch, the rule remains the same: measure the lug width and then select the corresponding strap width.
