Straum’s recent release of the Micro-Adjust Clasp for its bracelets is a godsend. It’s the accessory I knew I needed but perhaps not quite how much. As a proud owner of a Jan Mayen Fratello Limited Edition, I was excited to see how this upgrade would enhance the watch’s overall experience. Spoiler alert: it does not disappoint.Out of the box, the Micro-Adjust Clasp arrives in a small metal tin that fits snugly into the?Straum-branded accessory case included with all Jan Mayen watches. This thoughtful touch underscores Straum’s attention to detail, and it’s well appreciated. Installing the clasp on my Jan Mayen was straightforward thanks to the included pin-and-collar system and the bracelet tool that also came with the watch. Once in place, the clasp is almost indistinguishable from the stock butterfly clasp. Its minimalist design perfectly integrates with the bracelet, maintaining the sleek and robust aesthetic that defines Straum’s design DNA. Straum’s impressive design and build qualityCrafted from 316L stainless steel, the clasp combines bead-blasted, brushed, and polished finishes that perfectly match the bracelet’s original textures. Straum’s reputation for high standards is evident here - the machining is precise, the tolerances are tight, and the overall finish is flawless.A quick visual reminder of the Straum Fratello Jan Mayen Limited EditionOne of the clasp’s most notable aspects isn’t obvious until you get it on the wrist. Impressively, it adds the required micro-adjust functionality without sacrificing any of its design integrity. Even with the additional micro-adjustment mechanism, the clasp remains slim and discreet and doesn’t disrupt the continuous visual harmony of the bracelet. Knowing Lasse and ?ystein’s personalities and background in industrial design, I’m sure this was paramount during the design phase.Micro-adjust done rightStraum’s Micro-Adjust Clasp provides up to 4mm of on-the-fly adjustment, split into three positions (2mm on each side). This may not sound like much on paper, but it makes a difference in practice. It offers the perfect amount of adjustment to combat wrist swelling/shrinking. The dual push buttons operate the adjustment mechanism, engaging a comfortingly secure and precise ratchet system. View this post on InstagramA post shared by Straum (@straum)
