Fat Spring Bars Built for the heavyweights. If you’re rocking a serious dive watch that demands robust hardware, our stainless steel Fat Spring Bars are up to the task. Modeled heavily after the legendary "Seiko Fat" spring bars, these are thick, incredibly durable, and engineered to provide maximum security for your heavy-duty timepieces. Sold as a pair, these feature a small flange on the shoulder to give your tool a point of contact, but they do require specific watch case features for a proper fit. Specifications The Body (2.4mm): An extra-thick barrel designed for heavy-duty rubber dive straps and specialized heavy-canvas bands. The Tip (0.9mm): Oversized pins built to lock securely into watches designed with larger lug holes. Material: High-quality, heavy-duty stainless steel. Fit & Compatibility These spring bars are specifically designed for watches with drilled lugs (where the holes go all the way through the outside of the case) and larger lug holes. Because the flange is very small and the tips are oversized, installing them on a standard watch case without drilled lugs can make them extremely difficult to remove. Looking for different options? Need to fit a standard strap on your dive watch? A 2.4mm thick spring bar will not fit through most standard leather or nylon straps. If you have a dive watch with oversized lugs but want to use standard straps, or just want tool-free swapping, check out our Skinny Fat Quick-Release Spring Bars. Just need regular hardware? If you are outfitting a standard everyday watch, field watch, or dress piece, these fat bars will not fit your lug holes. Head over to our Standard Spring Bars instead. Available in 20mm and 22mm.
