2 Integrated fitment Options for Custom Watch Straps
2 Integrated fitment Options for Custom Watch Straps – At Dangerous9straps, we continuously push the boundaries of watch strap design with our innovative upgrades, notably the ‘Thick Curved Lug System’ (TCLS) and the ‘Fully Integrated Fit’ (FIF) upgrades. These features are designed to elevate both the aesthetic appeal and the functionality of our straps, offering a truly bespoke experience for discerning watch enthusiasts.
Thick Curved Lug System (TCLS)

The Thick Curved Lug System (TCLS) is engineered to provide a seamless connection between the watch strap and the case, ensuring a perfect fit that enhances both comfort and style. By precisely matching the natural curve of a watch’s lugs, the TCLS allows the strap to sit flush against the case, creating a cohesive, integrated look. This not only improves the overall aesthetic by eliminating gaps but also ensures that the strap distributes the watch’s weight evenly across the wrist. The TCLS is especially beneficial for watches with larger cases, providing a secure and comfortable fit that makes even substantial timepieces feel balanced and comfortable for extended wear.
Fully Integrated Fit (FIF) with Notching:

The Fully Integrated Fit (FIF) upgrade takes the TCLS concept to the next level by offering a strap that is fully molded to the exact contours of the watch case. With the addition of notching to the full width of the lugs, this upgrade ensures that the strap perfectly aligns with the watch case, extending from edge to edge with precision. This meticulous attention to detail eliminates any visible gaps between the strap and the case, creating a unified and sleek appearance that highlights the watch’s design. The notching not only enhances the visual continuity of the watch and strap but also adds to the structural integrity, ensuring the strap remains securely in place even during vigorous activities.
The Measurements that I May Need the Customer to Provide:
Each strap made with our ‘Thick Curved Lug System’ (TCLS) and Fully Integrated Fit’ (FIF) are custom made by myself in our Munich workshop to fit the exact model watch for which the strap is intended and so if I have no experience with your model watch (and assuming I don’t have your watch in hand) I will request that you provide a couple of measurments from your watch. To take these measurments with the accuracy will require removal of the strap/bracelet and just the installation of the spring bar or lug bar alone.
