Here's our complete guide.The history of the NATO strapThe NATO takes its name from the British Ministry of Defence's reference code in the 1970s. A single fabric band passes under the watch case: if a spring bar breaks, the watch remains on the wrist.

Choosing a watch strap without knowing the correct measurements is like buying shoes without knowing your size. A strap that is too wide will float between the lugs; a strap that is too short will constrict your wrist. Here is our complete measurement guide.Lug width: the essential measurementLug width is the distance in millimeters between the two lugs of your watch. This is THE measurement you need to know first.How to measure it: Place a rigid ruler between the two inner lugs of your watch. Measure to the nearest millimeter. Common sizes are 18, 19, 20, 21, 22, and 24 mm.Caution: Do not rely on the case diameter. A 40 mm watch can have a lug width of 20 mm or 22 mm.Lug widths by brand Rolex Submariner, GMT-Master, Daytona: 20 mm Omega Speedmaster Professional: 20 mm Panerai Luminor: 24 mm Tudor Black Bay: 22 mm IWC Portugieser: 20 or 22 mm If in doubt, contact our experts with a photo of your watch.Wrist circumference: choosing the right lengthMeasure your wrist with a flexible tape measure, without tightening, just above the wrist bone. Slim wrist (less than 16 cm): short length — 105/65 mm Medium wrist (16 to 19 cm): standard length — 115/75 mm Large wrist (more than 19 cm): long length — 120-130/80 mm Most of our calfskin leather straps are available in several lengths.Buckle widthMost straps taper between the lug and the buckle. Measure the width where the buckle inserts.

Avoid flexible tape measures that can slip.Can I put a 20 mm strap on a 21 mm lug width?A 1 mm difference is acceptable. A difference of 2 mm or more will be visible and risks causing lateral movement.Is the length the same for men and women?No. Women's wrists: 14-16 cm, men's: 16-20 cm.

Learn moreThe challenge of insert bracelets
Some luxury watches (such as Patek Philippe Nautilus, Audemars Piguet Royal Oak, or Hublot) use inserts (metal or plastic parts) inside their straps. These inserts ensure a perfect integration of the strap with the watch case, both aesthetically and technically. However, this makes replacing the strap complex: a standard strap cannot be properly fitted to these models. Solutions offered by MisterChrono To replace these specific straps while maintaining custom quality, the MisterChrono workshop offers three technical solutions depending on your watch model: Existing MisterChrono Inserts: For some very popular models (AP Royal Oak, Patek Nautilus, Cartier Santos Dumont), MisterChrono has already developed its own metal or brass inserts. Insert Transfer (The "Sacrifice"): For other models, MisterChrono needs to retrieve the inserts from one of your old straps. Process: Your old strap is dismantled to extract the insert, which is then hand-covered with new leather. Condition: The retrieved insert must be in good condition. This operation is impossible with a 100% metal strap. Advice: If you wish to keep your original strap intact, it is recommended to purchase a cheap used strap to serve as a "donor" for the inserts. Lead Times and Costs Due to the technical complexity and meticulous manual work (covering around the insert), please allow for: An additional cost of €100 compared to the price of a classic custom strap. A manufacturing lead time of approximately 3-4 weeks. Installation Mounting these straps is more delicate than a classic strap. In-store: Installation is free. Remote: It is highly recommended to have the strap installed by a qualified watchmaker.

How to know if a bracelet fits your wrist
Length, fit and comfort: how to choose the right watch strap A watch strap isn't chosen solely for its aesthetics. Its size, fit, and comfort play a crucial role in the everyday experience. An ill-fitting strap can not only be uncomfortable but also detract from the watch's elegance and durability. Here's how to ensure your strap fits your wrist perfectly. Bracelet length: an essential criterion The bracelet length should correspond precisely to the circumference of your wrist. A bracelet that is too long will create an unsightly excess, while a bracelet that is too short will put excessive strain on the watch and buckle. As a general rule: A slim wrist requires a shorter bracelet than the market standard. An average wrist can often fit a standard bracelet. A strong wrist will benefit from a longer or custom-made bracelet. 💡 Tip : Measure your wrist with a flexible measuring tape, without pulling it too tight, to obtain a reliable measurement. What is the ideal fit? A well-fitting bracelet should hold the watch in place without compressing the wrist. Ideally, you should be able to slide a finger between the bracelet and your skin. A good fit allows: Improved watch stability Optimal dial reading Lasting comfort throughout the day Bracelet too tight or too loose: the signs to recognize A bracelet that is too tight can cause: A feeling of discomfort Marks on the skin Premature wear of the leather or seams A bracelet that is too loose can cause: Excessive watch movements Repeated impacts against the wrist A loss of visual elegance In both cases, the watchmaking experience is compromised. Everyday comfort comes first Comfort is often underestimated when choosing a bracelet. Yet, a well-fitting bracelet moves with you without restriction, whether at work, while traveling, or in everyday life. The choice of material (leather, rubber, textile), the flexibility of the strap and the quality of the buckle directly influence this comfort. Conclusion A strap that fits your wrist beautifully enhances your watch, improves its everyday wear, and prolongs its lifespan. Size, fit, and comfort are just as important as design. Are you unsure about the size or fit of your bracelet? 👉 Discover our selection of bracelets adapted to every wrist or contact us for personalized advice and find the bracelet perfectly suited to your watch.

⌚ Complete Guide to Choosing Your Watch Strap Choosing the right watch strap ensures both style and comfort. Follow these simple steps. If you have any questions, please don't hesitate to contact us for personalised advice. Step 1: Determine the strap Width (Lug Width) This is the most crucial measure for adjustment. Measure the lug width: Always measure the space between the lugs of the watch (where the strap attaches to the case) and not your old strap (which may have shrunk). Check this tip: The width is often engraved on the back of your current strap. Example: If the space between the lugs measures 22 mm, you need a 22 mm strap. Step 2: Choose the strap Length The ideal Length depends on the size of your wrist. A. If you know the current Length: Lay the watch flat. Measure the loop part (Part A , without the loop itself). Measure the tip section (Part B ). Total Length = A + B B. If you would like a new Length (Wrist): Measure your wrist with a tape measure and use the size chart to find the ideal size (Length A+B combined): Wrist circumference Total Length (A+B) strap Size Less than 170 mm 160 mm S 170 to 190 mm 180 mm M 190 to 210 mm 200 mm L Over 210 mm 220 mm XL Step 3: Choose the Loop Type and Width The type of clasp influences both aesthetics and security. Pay attention to the measurement: For the buckle, measure the width of the strap where the buckle attaches , as many straps taper (are thinned) between the lug and the clasp. Classic Loop Types: Loop Type Description Compatibility Ardillon Loop The classic pin clasp (or tang clasp). Simple, reliable and very easy to use. Suitable for all non-metallic straps. Simple Deployment Buckle A locking system with a single V-shaped hinge. Opens and closes from one side only. Adds a touch of elegance and reduces wear on the strap. Butterfly Deployment Buckle Double hinge clasp that unfolds symmetrically on both sides. Offers excellent support and maximum discretion. MisterChrono offers a wide selection of pin buckles, single or double folding (butterfly) buckles. Don't hesitate to contact us for more details about our products!
